GPS World - January 2008 - (Page 35)

GPS front, in partnership with ADI we have created a new chipset, which will be available in mid-2008. We have benchmarked the performance of our solution with the best in the industry and are confident about its success. It is an autonomous GPS and its variant uses assisted GPS protocols using GSM, GPRS, or CDMA networks. AC: Tell us about GAGAN project. JR: GPS-Aided Geo-Augmented Navigation System (GAGAN) is the Indian SBAS. We are not directly working with the GAGAN program yet, though we have used NexNav to track the GAGAN satellite. We look forward to working in the initial experimental phase. We have been working with the Indian Space Research Organizatin (ISRO) since 1999. ISRO has used our GPS-based satellite positioning systems for all their LEO missions for the past eight years. AC: How will GAGAN affect the international GNSS marketplace? JR: WAAS in the United States and MSAS in Japan are now operational. EGNOS will be ready soon in Europe. However, there is a gap between EGNOS and MSAS which will be filled in effectively by GAGAN, so that one can have seamless travel from Europe to the Asia-Pacific region. Another very important aspect is that the problem of large ionospheric scintillation in the Indian region will have to be solved before GAGAN can be declared operational. The ionosphere is very turbulent in equatorial and tropical regions. It’s a big challenge to model the ionosphere well enough to get required GPS performance for aircraft navigation and landing. A lot of countries are waiting to see how this problem gets solved in India. Once solved here, it can be used elsewhere; the single-shell model used in WAAS and other regions is not really applicable for India. Once GAGAN becomes operational, similar systems can come up in countries such as Brazil. The International Civil Aviation Organization (ICAO) has a mandate that eventually aircraft navigation should primarily use satellite-based systems such as GPS, GLONASS, or Galileo along with SBAS and/or ground-based augmentation systems (GBAS). So it is all but certain that eventually the world will adopt GAGAN or WAAS-like systems. GAGAN is expected be operational around 2010 or 2011.
