UK Royal Academy of Engineering Issue Report on GNSS Vulnerability

Release of a British Royal Academy of Engineering (RAE) report today (March 8, 2011) adds another chapter to the growing chronicle of GNSS vulnerability — concluding that the integrity of GNSS is insufficient for safety-of-life applications.

Spectracom Launches GSG-55 GPS/SBAS Constellation Simulator

Spectracom has announced its new 16-channel GPS constellation simulator, the Pendulum GSG-55.

The latest in the Pendulum line of GPS receiver test instruments, the GSG-55 is able to simulate Satellite-Based Augmentation Systems (SBAS), such as the U.S. Wide Area Augmentation System and the European Geostationary Navigation Overlay Service (EGNOS).

JAXA Selects Spirent Simulator for QZSS Receiver Testing

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.

GNSS Interoperability

In the beginning, there was only the NAVSTAR Global Positioning System (GPS): an astounding start to the world of global navigation satellite systems (GNSS).

Since the United States declared full operational capability (FOC) for GPS in 1995, two major things have occurred:

Galileo Mid-Term Review Foresees €1.9 Billion in Additional Costs

A European Commission (EC) communication sent to the European Parliament and European Council today (January 18, 2011) estimates that completing a fully operational capability (FOC), 30-satellite Galileo system and the European Geostationary Navigation Overlay Service (EGNOS) will cost an additional €1.9 billion above the €3.4 billion already allocated.

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.

European Space Council Backs Galileo; 2011 Funding Still Unresolved

While funding and technical issues continue to roil the waters at the program and operational level, Galileo and the European Geostationary Navigation Overlay Service (EGNOS) have received a strong reaffirmation of support from the highest levels of the European Union (EU) and the European Space Agency (ESA).
