The U.S’ second Advanced Extremely High Frequency satellite has reached geosynchronous reached orbit after a four-month journey. The Space and Missile Systems Center will continue to hold satellite control authority of AEHF-2 during the testing phase, then transfer satellite control authority to the 14th Air Force and 4th SOPS at a later date. "During this testing phase, some capabilities require the use of AEHF-1, a 4th SOPS asset, hence the reason for the involvement of 4th SOPS personnel," said Lt. Col. Alistair Funge, 4th SOPS director of operations. "Our engineering shop, led by Maj. Yingwai Chan, is involved in day-to-day testing, coordinating ground support system time with the 22nd Space Operations Squadron and keeping leadership informed of ongoing activities". While 4th SOPS crews work with their counterparts at SMC and contractor Lockheed Martin to test the vehicle, the teams also must integrate AEHF-2 into the Milstar/AEHF constellation. "This transition process worked well with AEHF-1 and we expect it to be just as smooth with AEHF-2," Funge said. "This way, 4th SOPS crews and engineering support staff will also get hands-on experience with AEHF-2 during these activities. Throughout the test period, 4th SOPS members will monitor the constellation using our in-band Advanced Satellite Mission Control Subsystem and Space-Ground Link System as well as perform routine and test related operations". Four satellites are currently planned to complete the AEHF constellation. The third AEHF satellite is tentatively scheduled for launch in 2013.
