Section 2: The Critical Contour Point Technique The critical contour point (CCP) technique has been developed to assist in the determination of interference from an ESV. The technique involves calculating the interference from all points along the route of the ESV and determining which point produces the worst case interference into a victim microwave receiver. The worst case interference level is then calculated for this point. If the calculated interference exceeds the maximum long- term permissible level of interference, which is shown in Table 1 above, then the licensed or coordinated receive frequencies for that site must be avoided in order to preclude interference. The following section is excerpted from ITU-R SF 1649, which describes the CCP in more detail: For any interference exposure of a particular FS receiver from an ESV terminal on a moving ship, there are three position-related variables in the calculation: – Propagation loss exceeded for all but a percentage of time. This loss depends on the length of the interference path, the radio-climatic zones and may include the effects of any blockage that may exist on the interference path; – FS receiver antenna gain; and – ESV antenna horizon gain. For every point within the operating contour as defined by the deep-draft channel (see Fig. 2), each of these three factors can be readily determined. 3

FIGURE 1 Basic interference geometry FS receiver FS path Deep-draft channel Limits of sea-lanes Pier Interference exposures FIGURE 2 – BASIC INTERFERENCE GEOMETRY For the purpose of evaluating the potential interference the operating contour is approximated by a set of straight-line segments. The identification of the CCPs depends on the position and alignment of the FS path with respect to the operating contour, and several cases need to be distinguished. In those cases where the azimuth of the main beam axis of the FS antenna does not intersect with any portion of the operating area of the ESV, the critical contour points are the points along the operating contour where the contour changes direction or reaches the off-shore limit beyond which coordination is not required. In those cases where the azimuth of the main beam axis of the FS antenna intersects the operating contour it is necessary to augment and/or modify the number of CCPs. In any event, the same CCPs should be used to consider both the long-term and the short- term interference to any FS station under consideration. Interference from in-motion ESV operations to any FS receiver within the area where the potential interference from the ESV needs to be evaluated is assessed by consideration of the operation at each of the CCPs for each receiver using propagation 4

loss models such as those given in recommendation ITU-R P.452. The goal of this assessment is the identification of frequencies that can be used for in-motion ESV operations without causing unacceptable levels of interference to FS stations. For the identification of the CCPs with respect to a specific FS receiver, the following three cases need to be distinguished: Case 1: in this case the main beam axis of the FS receiving antenna does not intersect any portion of the operating contour. The only CCPs required for this case are the points where the operating contour of the ESV changes direction. Case 2: in this case, the main beam of the FS antenna (within 10 db of the maximum antenna gain) lies entirely within one segment of the operating contour. The points on the operating contour where the antenna gain is 10 db below the maximum, determine two additional CCPs. The segment of the operating contour between these two CCPs contains the natural intersection point (nip), the point where the main beam axis of the FS antenna intersects the operating contour. The nip is always taken as a CCP. Case 3: in this case, the nip is close enough to one of the points where the operating contour changes direction that the main beam of the FS antenna extends over more than one segment of the operating contour. This case is most likely to arise when the nip is close to one of the points where the operating contour of the ESV changes direction. The intersection of the operating contour with the antenna 10 db points determine two additional CCPs as in case 2; however, in this case the original point within the main beam does not need to be considered as a CCP. A further possibility: if there is a point on the operating contour of an ESV from which the maximum horizon gain of the ESV antenna is directed toward a FS receiver, that point on the contour may be identified as an additional CCP for that FS receiver regardless of which of the three cases applies. The CCP always represents the worst-case interference scenario and the associated exclusion zone mitigates all interference into an FS receiver for the ESV route. Once the CCP is determine an interference zone where the ESV transmissions into the victim receiver will exceed the maximum permissible interference criteria is developed based upon the receive antenna pattern of the terrestrial station. Within these zones the interfered spectrum must be avoided. The interference zones are detailed in the attached ESV Interference Analysis excel workbook. 5

Section 2: The Critical Contour Point Technique The critical contour point (CCP) technique has been developed to assist in the determination of interference from an ESV. The technique involves calculating the interference from all points along the route of the ESV and determining which point produces the worst case interference into a victim microwave receiver. The worst case interference level is then calculated for this point. If the calculated interference exceeds the maximum long- term permissible level of interference, which is shown in Table 1 above, then the licensed or coordinated receive frequencies for that site must be avoided in order to preclude interference. The following section is excerpted from ITU-R SF 1649, which describes the CCP in more detail: For any interference exposure of a particular FS receiver from an ESV terminal on a moving ship, there are three position-related variables in the calculation: – Propagation loss exceeded for all but a percentage of time. This loss depends on the length of the interference path, the radio-climatic zones and may include the effects of any blockage that may exist on the interference path; – FS receiver antenna gain; and – ESV antenna horizon gain. For every point within the operating contour as defined by the deep-draft channel (see Fig. 2), each of these three factors can be readily determined. 3

FIGURE 1 Basic interference geometry FS receiver FS path Deep-draft channel Limits of sea-lanes Pier Interference exposures FIGURE 2 – BASIC INTERFERENCE GEOMETRY For the purpose of evaluating the potential interference the operating contour is approximated by a set of straight-line segments. The identification of the CCPs depends on the position and alignment of the FS path with respect to the operating contour, and several cases need to be distinguished. In those cases where the azimuth of the main beam axis of the FS antenna does not intersect with any portion of the operating area of the ESV, the critical contour points are the points along the operating contour where the contour changes direction or reaches the off-shore limit beyond which coordination is not required. In those cases where the azimuth of the main beam axis of the FS antenna intersects the operating contour it is necessary to augment and/or modify the number of CCPs. In any event, the same CCPs should be used to consider both the long-term and the short- term interference to any FS station under consideration. Interference from in-motion ESV operations to any FS receiver within the area where the potential interference from the ESV needs to be evaluated is assessed by consideration of the operation at each of the CCPs for each receiver using propagation 4

loss models such as those given in recommendation ITU-R P.452. The goal of this assessment is the identification of frequencies that can be used for in-motion ESV operations without causing unacceptable levels of interference to FS stations. For the identification of the CCPs with respect to a specific FS receiver, the following three cases need to be distinguished: Case 1: in this case the main beam axis of the FS receiving antenna does not intersect any portion of the operating contour. The only CCPs required for this case are the points where the operating contour of the ESV changes direction. Case 2: in this case, the main beam of the FS antenna (within 10 db of the maximum antenna gain) lies entirely within one segment of the operating contour. The points on the operating contour where the antenna gain is 10 db below the maximum, determine two additional CCPs. The segment of the operating contour between these two CCPs contains the natural intersection point (nip), the point where the main beam axis of the FS antenna intersects the operating contour. The nip is always taken as a CCP. Case 3: in this case, the nip is close enough to one of the points where the operating contour changes direction that the main beam of the FS antenna extends over more than one segment of the operating contour. This case is most likely to arise when the nip is close to one of the points where the operating contour of the ESV changes direction. The intersection of the operating contour with the antenna 10 db points determine two additional CCPs as in case 2; however, in this case the original point within the main beam does not need to be considered as a CCP. A further possibility: if there is a point on the operating contour of an ESV from which the maximum horizon gain of the ESV antenna is directed toward a FS receiver, that point on the contour may be identified as an additional CCP for that FS receiver regardless of which of the three cases applies. The CCP always represents the worst-case interference scenario and the associated exclusion zone mitigates all interference into an FS receiver for the ESV route. Once the CCP is determine an interference zone where the ESV transmissions into the victim receiver will exceed the maximum permissible interference criteria is developed based upon the receive antenna pattern of the terrestrial station. Within these zones the interfered spectrum must be avoided. The interference zones are detailed in the attached ESV Interference Analysis excel workbook. 5

Section 2: The Critical Contour Point Technique The critical contour point (CCP) technique has been developed to assist in the determination of interference from an ESV. The technique involves calculating the interference from all points along the route of the ESV and determining which point produces the worst case interference into a victim microwave receiver. The worst case interference level is then calculated for this point. If the calculated interference exceeds the maximum long- term permissible level of interference, which is shown in Table 1 above, then the licensed or coordinated receive frequencies for that site must be avoided in order to preclude interference. The following section is excerpted from ITU-R SF 1649, which describes the CCP in more detail: For any interference exposure of a particular FS receiver from an ESV terminal on a moving ship, there are three position-related variables in the calculation: – Propagation loss exceeded for all but a percentage of time. This loss depends on the length of the interference path, the radio-climatic zones and may include the effects of any blockage that may exist on the interference path; – FS receiver antenna gain; and – ESV antenna horizon gain. For every point within the operating contour as defined by the deep-draft channel (see Fig. 2), each of these three factors can be readily determined. 4

The identification of the CCPs depends on the position and alignment of the FS path with respect to the operating contour, and several cases need to be distinguished. In those cases where the azimuth of the main beam axis of the FS antenna does not intersect with any portion of the operating area of the ESV, the critical contour points are the points along the operating contour where the contour changes direction or reaches the off-shore limit beyond which coordination is not required. In those cases where the azimuth of the main beam axis of the FS antenna intersects the operating contour it is necessary to augment and/or modify the number of CCPs. In any event, the same CCPs should be used to consider both the long-term and the short- term interference to any FS station under consideration.

loss models such as those given in recommendation ITU-R P.452. The goal of this assessment is the identification of frequencies that can be used for in-motion ESV operations without causing unacceptable levels of interference to FS stations. For the identification of the CCPs with respect to a specific FS receiver, the following three cases need to be distinguished: Case 1: in this case the main beam axis of the FS receiving antenna does not intersect any portion of the operating contour. The only CCPs required for this case are the points where the operating contour of the ESV changes direction. Case 2: in this case, the main beam of the FS antenna (within 10 db of the maximum antenna gain) lies entirely within one segment of the operating contour. The points on the operating contour where the antenna gain is 10 db below the maximum, determine two additional CCPs. The segment of the operating contour between these two CCPs contains the natural intersection point (nip), the point where the main beam axis of the FS antenna intersects the operating contour. The nip is always taken as a CCP. Case 3: in this case, the nip is close enough to one of the points where the operating contour changes direction that the main beam of the FS antenna extends over more than one segment of the operating contour. This case is most likely to arise when the nip is close to one of the points where the operating contour of the ESV changes direction. The intersection of the operating contour with the antenna 10 db points determine two additional CCPs as in case 2; however, in this case the original point within the main beam does not need to be considered as a CCP. A further possibility: if there is a point on the operating contour of an ESV from which the maximum horizon gain of the ESV antenna is directed toward a FS receiver, that point on the contour may be identified as an additional CCP for that FS receiver regardless of which of the three cases applies. The CCP always represents the worst-case interference scenario and the associated exclusion zone mitigates all interference into an FS receiver for the ESV route. Once the CCP is determine an interference zone where the ESV transmissions into the victim receiver will exceed the maximum permissible interference criteria is developed based upon the receive antenna pattern of the terrestrial station. Within these zones the interfered spectrum must be avoided. The interference zones are detailed in the attached ESV Interference Analysis excel workbook. 6

Section 2: The Critical Contour Point Technique The critical contour point (CCP) technique has been developed to assist in the determination of interference from an ESV. The technique involves calculating the interference from all points along the route of the ESV and determining which point produces the worst case interference into a victim microwave receiver. The worst case interference level is then calculated for this point. If the calculated interference exceeds the maximum long- term permissible level of interference, which is shown in Table 1 above, then the licensed or coordinated receive frequencies for that site must be avoided in order to preclude interference. The following section is excerpted from ITU-R SF 1649, which describes the CCP in more detail: For any interference exposure of a particular FS receiver from an ESV terminal on a moving ship, there are three position-related variables in the calculation: – Propagation loss exceeded for all but a percentage of time. This loss depends on the length of the interference path, the radio-climatic zones and may include the effects of any blockage that may exist on the interference path; – FS receiver antenna gain; and – ESV antenna horizon gain. For every point within the operating contour as defined by the deep-draft channel (see Fig. 2), each of these three factors can be readily determined. 5

FIGURE 1 Basic interference geometry FS receiver FS path Deep-draft channel Limits of sea-lanes Pier Interference exposures FIGURE 2 – BASIC INTERFERENCE GEOMETRY For the purpose of evaluating the potential interference the operating contour is approximated by a set of straight-line segments. The identification of the CCPs depends on the position and alignment of the FS path with respect to the operating contour, and several cases need to be distinguished. In those cases where the azimuth of the main beam axis of the FS antenna does not intersect with any portion of the operating area of the ESV, the critical contour points are the points along the operating contour where the contour changes direction or reaches the off-shore limit beyond which coordination is not required. In those cases where the azimuth of the main beam axis of the FS antenna intersects the operating contour it is necessary to augment and/or modify the number of CCPs. In any event, the same CCPs should be used to consider both the long-term and the short- term interference to any FS station under consideration. Interference from in-motion ESV operations to any FS receiver within the area where the potential interference from the ESV needs to be evaluated is assessed by consideration of the operation at each of the CCPs for each receiver using propagation 6

loss models such as those given in recommendation ITU-R P.452. The goal of this assessment is the identification of frequencies that can be used for in-motion ESV operations without causing unacceptable levels of interference to FS stations. For the identification of the CCPs with respect to a specific FS receiver, the following three cases need to be distinguished: Case 1: in this case the main beam axis of the FS receiving antenna does not intersect any portion of the operating contour. The only CCPs required for this case are the points where the operating contour of the ESV changes direction. Case 2: in this case, the main beam of the FS antenna (within 10 db of the maximum antenna gain) lies entirely within one segment of the operating contour. The points on the operating contour where the antenna gain is 10 db below the maximum, determine two additional CCPs. The segment of the operating contour between these two CCPs contains the natural intersection point (nip), the point where the main beam axis of the FS antenna intersects the operating contour. The nip is always taken as a CCP. Case 3: in this case, the nip is close enough to one of the points where the operating contour changes direction that the main beam of the FS antenna extends over more than one segment of the operating contour. This case is most likely to arise when the nip is close to one of the points where the operating contour of the ESV changes direction. The intersection of the operating contour with the antenna 10 db points determine two additional CCPs as in case 2; however, in this case the original point within the main beam does not need to be considered as a CCP. A further possibility: if there is a point on the operating contour of an ESV from which the maximum horizon gain of the ESV antenna is directed toward a FS receiver, that point on the contour may be identified as an additional CCP for that FS receiver regardless of which of the three cases applies. The CCP always represents the worst-case interference scenario and the associated exclusion zone mitigates all interference into an FS receiver for the ESV route. Once the CCP is determine an interference zone where the ESV transmissions into the victim receiver will exceed the maximum permissible interference criteria is developed based upon the receive antenna pattern of the terrestrial station. Within these zones the interfered spectrum must be avoided. The interference zones are detailed in the attached ESV Interference Analysis excel workbook. 7

Section 2: The Critical Contour Point Technique The critical contour point (CCP) technique has been developed to assist in the determination of interference from an ESV. The technique involves calculating the interference from all points along the route of the ESV and determining which point produces the worst case interference into a victim microwave receiver. The worst case interference level is then calculated for this point. If the calculated interference exceeds the maximum long- term permissible level of interference, which is shown in Table 1 above, then the licensed or coordinated receive frequencies for that site must be avoided in order to preclude interference. The following section is excerpted from ITU-R SF 1649, which describes the CCP in more detail: For any interference exposure of a particular FS receiver from an ESV terminal on a moving ship, there are three position-related variables in the calculation: – Propagation loss exceeded for all but a percentage of time. This loss depends on the length of the interference path, the radio-climatic zones and may include the effects of any blockage that may exist on the interference path; – FS receiver antenna gain; and – ESV antenna horizon gain. For every point within the operating contour as defined by the deep-draft channel (see Fig. 2), each of these three factors can be readily determined. 5

FIGURE 1 Basic interference geometry FS receiver FS path Deep-draft channel Limits of sea-lanes Pier Interference exposures FIGURE 2 – BASIC INTERFERENCE GEOMETRY For the purpose of evaluating the potential interference the operating contour is approximated by a set of straight-line segments. The identification of the CCPs depends on the position and alignment of the FS path with respect to the operating contour, and several cases need to be distinguished. In those cases where the azimuth of the main beam axis of the FS antenna does not intersect with any portion of the operating area of the ESV, the critical contour points are the points along the operating contour where the contour changes direction or reaches the off-shore limit beyond which coordination is not required. In those cases where the azimuth of the main beam axis of the FS antenna intersects the operating contour it is necessary to augment and/or modify the number of CCPs. In any event, the same CCPs should be used to consider both the long-term and the short- term interference to any FS station under consideration. Interference from in-motion ESV operations to any FS receiver within the area where the potential interference from the ESV needs to be evaluated is assessed by consideration of the operation at each of the CCPs for each receiver using propagation 6

loss models such as those given in recommendation ITU-R P.452. The goal of this assessment is the identification of frequencies that can be used for in-motion ESV operations without causing unacceptable levels of interference to FS stations. For the identification of the CCPs with respect to a specific FS receiver, the following three cases need to be distinguished: Case 1: in this case the main beam axis of the FS receiving antenna does not intersect any portion of the operating contour. The only CCPs required for this case are the points where the operating contour of the ESV changes direction. Case 2: in this case, the main beam of the FS antenna (within 10 db of the maximum antenna gain) lies entirely within one segment of the operating contour. The points on the operating contour where the antenna gain is 10 db below the maximum, determine two additional CCPs. The segment of the operating contour between these two CCPs contains the natural intersection point (nip), the point where the main beam axis of the FS antenna intersects the operating contour. The nip is always taken as a CCP. Case 3: in this case, the nip is close enough to one of the points where the operating contour changes direction that the main beam of the FS antenna extends over more than one segment of the operating contour. This case is most likely to arise when the nip is close to one of the points where the operating contour of the ESV changes direction. The intersection of the operating contour with the antenna 10 db points determine two additional CCPs as in case 2; however, in this case the original point within the main beam does not need to be considered as a CCP. A further possibility: if there is a point on the operating contour of an ESV from which the maximum horizon gain of the ESV antenna is directed toward a FS receiver, that point on the contour may be identified as an additional CCP for that FS receiver regardless of which of the three cases applies. The CCP always represents the worst-case interference scenario and the associated exclusion zone mitigates all interference into an FS receiver for the ESV route. Once the CCP is determine an interference zone where the ESV transmissions into the victim receiver will exceed the maximum permissible interference criteria is developed based upon the receive antenna pattern of the terrestrial station. Within these zones the interfered spectrum must be avoided. The interference zones are detailed in the attached ESV Interference Analysis excel workbook. 7

Table 4 provides a high level summary for each case CCP, including the CCP coordinates, interference margin, victim receive location, and affected licensee. 8
