Attachment B SES Americom, Inc. (“SES Americom”) seeks to withdraw a portion of the pending requests for special temporary authority (“STA”), File Nos. SES-STA-20080521- 00667/68, to use its licensed earth stations at Brewster, WA, Call Signs E990067 and E990068, to participate in testing of a U.K.-licensed geostationary mobile satellite services (“MSS”) satellite, ICO G1, at 92.85° W.L. In addition, SES Americom submits as Attachment C an acknowledgement from the local frequency coordinator for Brewster, WA, that the planned operations have received concurrence from BAS licensees in Eastern Washington State, provided that daily reports are submitted to the local frequency coordinator by the ICO G1 operator. Specifically, SES Americom asked to transmit and receive S-band signals in the 2000- 2015 MHz frequency band in the uplink, and in the full 2180-2200 MHz frequency band in the downlink. For purposes of this STA request, SES Americom hereby withdraws its request to receive S-band signals in the 2180-2200 MHz frequency band. The tables containing the relevant technical parameter that were previously submitted would instead read as follows: Table 1 Frequency Maximum Maximum Band Antenna Emission Tx/Rx EIRP EIRP density Carrier function (MHz) polarization designator mode (dBW) (dBW/4kHz) 2000.00-2015.00 R 156KG7W T 10.0 -5.90 QPSK test carrier 2000.00-2015.00 R 41K6G7W T 25.0 14.80 BPSK calibration carrier 2000.00-2015.00 R N0N T 49.70 49.70 CW carrier for calibration Table 2 Ant gain: Transmit and receive Total power at antenna flange (watts) Total EIRP for all carriers (dBW) 34.3 dBi at 2.0 GHz 30.0 54.3 34.9 dBi at 2.15 GHz Table 3 Frequency Range of Ant.
