Trimble to Acquire Fugro’s OmniSTAR DGPS Service

Omnistar DGPS world map

Trimble announced on March 16 that it has entered into a definitive agreement to acquire certain assets related to the OmniSTAR GNSS signal corrections business from Fugro N.V.

The acquisition is expected to significantly expand Trimble’s worldwide ability to provide correction services for a broad range of land-based applications in addition to OmniSTAR’s current focus in agriculture. Fugro’s offshore marine business is unaffected.

On March 2, ESSP (the European Satellite Services Provider) declared the safety-of-life (SoL) signal from the European Geostationary Navigation Overlay Service (EGNOS) officially available for use by aviation, following European Commission (EC) authorization to provide the service.

Similar to the U.S. Federal Aviation (FAA) Administration’s Wide Area Augmentation System (WAAS), EGNOS transmits real-time corrections to GPS signals over a large expanse of Europe and north Africa.

For the complete story, including figures, graphs, and images, please download the PDF of the article, above.

In satellite navigation, a GNSS receiver must account for several sources of error such as relativistic effects, atmospheric propagation delay, offset of satellite clocks from system time and satellite ephemeris. In order to accurately compute user position, velocity, and time (PVT), these errors need to be predicted/estimated precisely.

GMV Will Launch Fully Hosted Software GPS Receiver at Mobile World Congress

GMV will launch the SRX-10, a software GPS receiver for mass-market applications, at this year’s GSMA Mobile World Congress, scheduled February 14–17 in Barcelona, Spain.

As a fully hosted solution, all SRX-10 receiver functions — even signal acquisition and tracking — can be hosted on a general purpose CPU with only the requirement of adding on a low cost RF front-end, according to the company.
The company cites other benefits offered by its new software receiver, particularly its substantial flexibility and upgradeability.
