III. SECTION 25.227 CERTIFICATIONS Astronics AeroSat Corporation (“Astronics AeroSat”), pursuant to Section 25.227 of the FCC’s Rules, hereby certifies the following: 1. In accordance with Section 25.227(a)(15), as the operator of an ESAA system operating over international waters, Astronics AeroSat has confirmed with its target space station operators that its existing and proposed operations are within coordinated parameters for adjacent satellites up to six degrees away (+/- 6°) on the geostationary arc. 2. In accordance with Section 25.227(b)(7), Astronics AeroSat certifies that its existing and proposed operations comply with the following requirements of Section 25.227: • Per Section 25.227(a)(6), for each ESAA transmitter, Astronics AeroSat will time annotate and maintain a record for a period of not less than one year of the vehicle location (i.e., latitude/longitude/altitude), transmit frequency, channel bandwidth and satellite used. Records will be recorded at time intervals no greater than one (1) minute while the ESAA is transmitting. Astronics AeroSat will make this data available in the requisite format within 24 hours of a request from the Commission, NTIA, or a frequency coordinator for purposes of resolving harmful interference events. • Per Section 25.227(a)(9), each ESAA terminal will automatically cease transmitting within 100 milliseconds upon loss of reception of the satellite downlink signal or when it detects that unintended satellite tracking has happened or is about to happen. • Per Section 25.227(a)(10), each ESAA terminal will be subject to the monitoring and control by an NCMC. Each terminal will be able to receive “enable transmission” and “disable transmission” commands from the NCMC and must automatically cease transmissions immediately on receiving any “parameter change command”, which may cause harmful interference during the change, until it receives an “enable transmission” command from its NCMC. In addition, the NCMC will be able to monitor the operation of an ESAA terminal to determine if it is malfunctioning. • Per Section 25.227(a)(11), each ESAA terminal shall be self-monitoring and, should a fault which can cause harmful interference to FSS networks be detected, the terminal will automatically cease transmissions.
