Global Navigation Satellite Systems Engineering, Policy, and Design
Spirent Communications’ Positioning Technology Division, Paignton, UK, has announced that the Japanese Aerospace Exploration Agency (JAXA) has selected Spirent’s GSS8000 Multi-GNSS Constellation Simulator to support further development of the Quazi-Zenith Satellite System (QZSS) program.
Responsible for the development of the initial QZSS user equipment, JAXA is using the GSS8000 to verify QZSS receiver performance.

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 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.
NavCom Technology, Inc., has announced new capabilities for the SF-3050 multi-frequency GNSS receiver and Sapphire GNSS OEM board.
In addition to the integrated StarFire/real-time kinematic (RTK) GNSS capabilities, the SF-3050 and Sapphire now support single-frequency, multi-constellation operation, heading, and moving base station RTK operation that enables coordinated vehicle applications.

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).

Residenz entrance, familiar to Munich Satellite Navigation Summit attendees.The 2011 Munich Satellite Navigation Summit will take place from March 1 through 3 in Der Residenz, the palace of the old Bavarian royal family and now home to four museums.
The event features high-level discussions about all of the world’s navigation satellite systems. It is organized by the Institute of Geodesy and Navigation at University FAF Munich.
The technical program begines with a plenary presentation on "GNSS in Balance," followed by a Bavarian State Reception.
