The European GNSS Agency (GSA) has published its second GNSS market report, including a special focus on maritime and surveying application markets and refining its projections of unit and sales revenue volumes through 2020.
According to the new GSA report, the worldwide GNSS market is growing rapidly with total market size expected to increase at an average of 13 percent per year until 2016. At that point, increasing market saturation, price erosion, and platform convergence will reduce the growth rate.

The U.S. Air Force has awarded Lockheed Martin a $68 million contract to provide mission readiness, launch, early orbit checkout, and on-orbit operations engineering support for the first two GPS III space vehicles.
Under the contract, Lockheed Martin will provide technical support to the Air Force’s 2nd Space Operations Squadron (2SOPS) and monitor the health and performance of the first two GPS III satellites from launch through their 15-year operational design lives.

NovAtel Inc. today (May 30, 2012) announced the development of their OEM625S Selective Availability/Anti-Spoofing Module (SAASM) GNSS receiver, the first product emerging from a collaborative effort with L-3 Interstate Electronics Corporation (IEC).
The OEM625S, which becomes available for purchase in the third quarter of this year, will combine a commercial dual-frequency NovAtel GNSS receiver with an L-3 IEC XFACTOR SAASM in a single card solution, reducing overall size and power requirements for end customer applications.

Launch of the first GPS III satellite has slipped to 2015 and completion of the ground control system is now delayed by up to two years, according to the chief of the Air Force’s space operations
“We’ll be ready to launch the first GPS III in 2015, but it now appears the next generation GPS Operational Control System, or OCX, won’t be ready for about a year or two after that,” General William L. Shelton, commander of Air Force Space Command (AFSPC) told attendees at the 28th Annual National Space Symposium.

EQUATIONS 1 -11GLONASS currently uses a frequency division multiple access (FDMA) technique to distinguish the signals coming from different satellites in the Russian GNSS constellation. The GLONASS L1 and L2 bands are divided into 14 sub-bands, and each satellite transmits in one of these.
The sub-bands are identified by frequency numbers k, from -7 to 6. The GLONASS L1 and L2 carrier frequencies, in hertz, at a frequency number k are defined by:
Working Papers explore the technical and scientific themes that underpin GNSS programs and applications. This regular column is coordinated by Prof. Dr.-Ing. Günter Hein, head of Europe’s Galileo Operations and Evolution.
