Perspectives

New Signal, New Show

 

BY ALAN CAMERON     eic@questex.com

Change, always an active force at work in global navigation, keeps a-rollin’, rollin’ on. The number of satellites broadcasting the new L2C civil signal doubled last month, and may have tripled by the time you read this. The new, higher-powered IIR-Ms can also broadcast the new military signal. And highlighting growth and new directions for GNSS, a major new conference and industrial exhibition will take place next June, under the auspices of GPS World magazine.

 

On October 12, the Air Force Space Command's 2nd Space Operations Squadron (2 SOPS) at Schriever Air Force Base, Colorado, declared the second replenishment modernized (IIR-M) GPS satellite fully operational for military and civilian navigation users worldwide. A successful on-orbit deployment and check-out phase enabled the spacecraft, launched on September 25, to begin service ahead of planned schedule. Designed and built by Lockheed Martin, PRN31/SVN52 transmits the new L2C civil signal at 1227.5 MHz. Among the receivers able to decode this signal are Septentrio’s PolaRx2C, and Trimble 5700, Total Station 5700, 5800 and 5800 Rover, BD950 L1/L2, NetRS, R7, R8, and R8 GNSS receivers. The third Block IIR-M satellite is scheduled for liftoff on November 14 from Cape Canaveral. read more>>
