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.

Broadcom Announces Position Solution Using On-Orbit QZSS Satellite

Broadcom Corporation reports that for the first time it has been able to compute GNSS positions, using the first Quasi-Zenith Satellite System (QZSS) spacecraft. The Japan Aerospace Exploration Agency (JAXA) launched the Quasi-Zenith Satellite–1 (nicknamed Michibiki) on September 11 and recently started transmitting the QZSS ephemeris (orbital location coordinates).
