GPS Creations offers the GPS SIM14, an L1/L2 GPS constellation simulator available in either C/A code–only or C/A-code and P-code configurations, which can simulate up to 14 satellites simultaneously. The simulator can be integrated with a multi-function feature card (MFI/O) to provide extended capabilities such as IMU, automotive, and factory test & timing. An adjustable RF power output has a dynamic range of 66 dB.

CeBIT is the world’s largest information and communications technology exhibition, concentrating on the business-to-business, not the consumer, market.
The massive German trade fair at the Hannover Exhibition Center includes a dedicated Telematics and Navigation section in Halls 14 and 15.
It features indoor GPS reception for real time navigation and positioning at exhibitors’ booths.
A joint exhibit area is prominently located in the T & N section for the Galileo satellite navigation community

The GPS Wing has completed an integrated baseline review of the GPS IIIA program, the first major milestone for the $1.4 billion development and production contract for which Lockheed Martin serves as the prime contractor.
The IIIA contract, awarded earlier this year, provides for development and production of the first two GPS IIIA satellites with an initial launch set for 2014. The IBR paves the way for the establishment of an integrated cost, schedule, and technical baseline for the program.

PCTEL offers the GPSL1GL-TMG-40N timing reference antenna specifically designed for deployments in congested cell-site applications and able to receive signals from GPS, Galileo, and GLONASS satellites in the 1575.42 ± 10 MHz and 1602-1615 MHz frequency bands. The low-noise, high-gain amplifier is well suited to address attenuation issues associated with applications requiring longer cable runs. The proprietary quadrifiliar helix design, coupled with multistage filtering improves out-of-band rejection and lower elevation pattern performance.
