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. (See accompanying satellite-visibility graphic).

GAGAN Delayed Again

GAGAN Delayed Again

ISRO GSAT-4 satellite

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

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.

Canada to Decommission DGPS System

The Canada-wide DGPS Service (CDGPS), a free GNSS augmentation system initiated by the Canadian Council on Geomatics (CCOG) in 2003, will be decommissioned by March 31, 2011, according to Gary Sawayama, the system’s general manager.

The CDGPS L-band broadcast has been carried by SkyTerra Communications Inc.’s MSAT communications satellites, which are expected to be replaced this year by the next-generation SkyTerra satellites. Significant new investment in infrastructural changes would be required to migrate to a new communication satellite.

The European GNSS Supervisory Authority (GSA), on behalf of the European Commission, has launched an Internet portal for the European Geostationary Navigation Overlay Service (EGNOS) designed to help developers and entrepreneurs vying for a slice of the emerging satellite navigation market.

The European counterpart to the U.S. GPS Wide Area Augmentation System (WAAS), EGNOS is a satellite-based augmentation system that provides real-time differential corrections and integrity information about GPS operations.
