Air Force rebuts auditor’s concerns about GPS
A report from the Government Accountability Office, the investigative arm of Congress, said the latest GPS satellite was launched almost 3½ years behind schedule, and further delays could leave the system with fewer than the 24 orbiting satellites it needs as older models wear out and stop working. Col. David Buckman of the Air Force Space Command at Peterson Air Force Base said the report’s facts were correct, but “we think it draws overly pessimistic conclusions based on those facts.” Buckman said satellites currently in the design or construction phase are on schedule, and the Air Force has 31 healthy, operational satellites in orbit.

GPS chips in rhino horns
South African rangers plan to implant GPS devices in the horns of rhinos in a new effort to combat rampant poaching. The GPS chips link up to a computer monitoring station where park rangers track the rhinos. An alarm signal activates if the rhino lies inert for longer than is deemed normal, or becomes unusually active.

MICHIBIKI transmits L1-SAIF signal
JAXA has been conducting the initial functional verification of “MICHIBIKI,” including its attitude control and communications systems, and satellite bus. The functions of the attitude control and communications systems have been confirmed. Transmission of one of the positioning signals, namely the L1-SAIF signal (*1) from the L1-SAIF antenna (*2) of the MICHIBIKI started after turning on the onboard positioning mission devices. During the verification Non Standard Code (NSC) is being used.
