Exhibit 1 V11 ESV Terminal Technical Appendix 1. Introduction KVH Industries, Inc. (“KVH”) has developed a small aperture, broadband, highly efficient and affordable earth stations onboard vessels (“ESV”) terminal for use with its global maritime communications network. This ESV – the KVH V11 terminal – operates in Ku-band FSS frequencies (14.0-14.5 GHz transmit, 11.7-12.2 GHz receive, 10.95-11.2 GHz and 11.45-11.7 GHz receive). The V11 terminal will automatically search for and acquire the designated satellite, and maintain precise pointing via automatic control of the azimuth, elevation and polarization angles. The antenna being used in this ESV terminal is 1 meter in diameter, and its main lobe does not conform to the standards specified in Section §25.209(a) and (b). In order to compensate for this performance, KVH will operate with a spread spectrum modulation technique that will bring the off-axis EIRP spectral density of the terminal well within the spectral density limits specified in Section §25.222 of the Commission’s rules. This technical exhibit provides the showing required pursuant to Section §25.222, including detailed information regarding the ESV antenna patterns and off-axis emissions, and a summary of the remote ESV to hub link analysis. 2. Description of Antenna KVH has developed the small aperture, broadband, highly efficient and affordable V11 ESV terminal for use with its global ESV network. The ESV terminal operates in the Ku FSS frequency band, 14.0-14.5 GHz transmit and 10.95-11.2 GHz, 11.45-11.7 GHz and 11.7-12.2 GHz receive. The antenna is a 1 meter parabolic reflector with a rear-fed sub- reflector feed assembly design. The ESV terminal will automatically search for and acquire the designated satellite and maintain precise pointing via automatic control of the azimuth, elevation and polarization angles. The RF equipment is integrated into the base of the terminal and includes a 3 watt block upconverter. The proposed ESV uplink return transmission (inbound) channel supports data rates of 32 kbit/s, 64 kbit/s, 128 kbit/s, 256 kbit/s, and 512 kbit/s. The ESV uplink transmission utilizes a spread spectrum modulation. This authorization will require channel bandwidths of 18 MHz, 27MHz, and 36 MHz. The forward channel (outbound from the hub earth station to the ESV) will be between 3-10 Mbits/s aggregate with individual end user rates at 0.5-2Mbit/s. The forward channel is also spread over the 18 MHz, 27 MHz, or 36 MHz channel and is overlaid onto the same transponder spectrum using a technique called PCMA.1 1 Paired Carrier Multiple Access is a proprietary technique developed by ViaSat for their spread spectrum ArcLight service.

Description of Service As is shown in Figure 1 below, the V11 terminal will be operated within KVH’s existing broadband mobile maritime service network, authorized by the Commission.2 KVH is seeking authorization to operate within the continental United States (CONUS), Alaska and Hawaii, as well as U.S. territories and possessions, and adjacent waters within the satellite coverage zones. KVH would like to primarily operate the terminals with the following satellites: AMC-15 @ 105° W.L., AMC-21 @ 125º W.L., TelStar 11N at 37.5° W.L., and GE-23 @ 172º E.L. The ESVs will communicate with existing hub earth stations in Miami, Florida, Carlsbad, California, and Kapolei, Hawaii.3 KVH will control all V11 operations using its standard network control capabilities and network management services. Additionally, since this service will operate under the control of the KVH ESV network operations center there will be a record of the ESV’s location and operating parameters as specified in Section 25.222(a)(4). The service is designed as a regional service, covering the North American continent and its coastal waters, Central America, the Gulf of Mexico and the Caribbean, as well as the Pacific Ocean region, as shown in blue shade in Figure 2 below. 2 See File No. SES-LIC-20060824-01502 (Call Sign E060335); File No. SES-LIC- 20070504-00563 (Call Sign E070085); and File No. SES-LIC-20081104-01450 (Call Sign E090001). 3 Call Signs E040267, E030131 and E010236, respectively. 2

. Figure 1 – ESV Network Architecture Figure 2 – ESV Coverage Area The ESV terminal will operate in compliance with KVH’s coordination agreement with the National Science Foundation with respect to Radio Astronomy Service (“RAS”) sites 3

and will not operate within 125 km of the Tracking and Data Relay Satellite System (TDRSS) sites for space research conducted at White Sands, New Mexico and the U.S. Naval Research Lab at Blossom Point, Maryland.4 4. Off-Axis EIRP Analysis The data rates transmitted from the terminal will vary from 32 kbits/s to 512 kbits/s. Additionally, the ESVs will transmit using CRMA spreading5 over either an 18 MHz, 27 MHz, or 36 MHz channel bandwidth. KVH acknowledges that the small diameter V11 antenna does not meet the FCC 25.209 antenna pattern. However, KVH certifies that the aggregate EIRP levels do not exceed the limits specified for Ku-band ESVs in Section 25.222 of the Commission’s rules. The co-pol off-axis EIRP spectral density levels of the KVH ESV terminal are shown in Figures 3 through 6 below. Note that a calculated worst case aggregate EIRP occurs when N=16 users for the 36 MHz channel and when N=8 users for the 18 MHz channel.

KVH will accept technical limitations imposed on other Ku-band ESV operations necessary to protect TDRSS operations. See 47 C.F.R. § 25.222(c). 5 CRMA, or Code Reuse Multiple Access, is a ViaSat proprietary spread spectrum technique, similar to CDMA, used in the ArcLight satellite system. 4

5. Pointing Accuracy The ESV V11 terminal will utilize a motion stabilized tracking antenna and a direct sequence spread spectrum (DSSS) burst modem manufactured by ViaSat to access the satellite. The ESV terminal uses a common spreading code and a random access method called code reuse multiple access (“CRMA”) to access the satellite. CRMA is closely analogous to the more generally understood code division multiple access (CDMA) multiple access method, but differs in that all terminals use a common spreading code rather than a number of individual codes for each transmitter. Individual bursts are distinguished by time difference of arrival. The use of this spreading technique allows the RF spectral density for each ESV to be significantly lower that typical TDMA systems operating at Ku-band. The antenna system utilizes a conical scanning function and rate gyros to stabilize the antenna and keep it pointed properly at the desired satellite. The conscan is currently set to worst case 0.15º from boresight. The dynamic pointing error for the vessel accelerations expected during testing operation is expected to be less than 1.0º. Thus the total expected mean pointing error for each vessel while under way, including both conscan and dynamic error, is 1.15º, this is the declared maximum pointing error. During the small percentage of time when conditions cause the antenna pointing error to exceed the specified maximum pointing error limit of 1.15º, the antenna system will send a message to the modem, and the modem will inhibit transmission until the aggregate conscan plus dynamic pointing error value is back to within 1.0º. The time lag from detection of exceedance of mispointing to time when transmit is inhibited will be less than 100 ms. This error limit of 1.15º is the declared maximum antenna pointing error as described in §25.222(b)(1)(iv)(A). As described above, the Ku-band ESV terminals use a spread spectrum multiple access technique whereby the individual off-axis EIRP density of each ESV terminal is well below the maximum aggregate network limit. Thus, each antenna individually will not generate harmful levels of interference. Figure 7 below shows the ESV off-axis EIRP considering a more than worst case 1.25 degree pointing error. As can be seen the EIRP density complies with the Section 25.222 mask for an individual ESV terminal. 15
