New Multi-GNSS Demonstration Campaign Launched for Asia-Oceania

Interoperability in a world of multiple global navigation satellite systems—everybody talks about it, but not much has been done about it in practice. The Japanese Aerospace Exploration Agency (JAXA) hopes to change that with a five-year campaign demonstrating the benefits and opportunities of maximizing the use of the more than 100 GNSS space vehicles that will be operating over the Asia-Oceania region in the next decade.

ESA Sponsors GNSS Summer School this September in Denmark

Online registration is open for the fourth International Summer School on Global Navigation Satellite systems. The 10-day course will take place at the GPS Center at Aalborg University in Slettestrand, Denmark from Wednesday afternoon, September 1 through Saturday morning, September 11.

Held for the first two years at University FAF Munich, it now takes place in Denmark with two new lead sponsors, the European Space Agency and Nokia.

CAPS — China’s Regional Navigation Satellite System

Many navigation satellite systems have emerged since 2000.

GPS is the first global navigation satellite system (GNSS), followed by Russia’s GLONASS, reinvigorated in recent years. Europe is developing Galileo, and China is expanding the regional system Beidou to a global system called Compass (also referred to as Beidou-2).

GAGAN Delayed Again

India’s first GPS/SBAS payload, the GAGAN (GPS-Aided Geo-Augmented Navigation system) transmitter on the GSAT-4 geostationary satellite, disappeared into the Bay of Bengal on April 15 when its ill-fated GSLV-D3 launch vehicle veered off course.

The Indian Space Research Organization's GSAT-4 satellite carried a communication payload of multi-beam Ka-band pipe and regenerative transponder and a navigation payload in C, L1 and L5 bands.

A key part of India’s GPS augmentation plan, the failure will further delay civil aviation modernization.

FAA Predicts Erosion of GPS WAAS Service Due to Intelsat GEO Failure

[updated April 13] Federal Aviation Administration (FAA) officials say that loss of control over an Intelsat geostationary (GEO) carrying a GPS Wide Area Augmentation System (WAAS) transponder could subject users in the National Air Space (NAS) to temporary outages for the rest of this year, beginning within the next two to four weeks as the GEO drifts out of a useable orbit.

Intelsat S.A. announced the anomaly in Galaxy 15 (G-15) on April 8. Although the communications services provided by G-15, located at 133 degrees west longitude (WL), have not been affected, according to Intelsat, the satellite apparently is not responding to commands by controllers. The anomalous condition began on April 3, according to the FAA.

The Luxembourg-based Intelsat is moving an older spacecraft (G-12) that serves as a backup for G-15 from its location at 123 degrees WL. However, G-12 does not have an L-band transponder, which is needed for WAAS transmissions.
