This issue is a concern for reliable operation of safety-critical GPS systems, such as marine DGPS services or Satellite-Based Augmentation Systems (SBAS) for aviation applications. These storm-related effects tend to peak in the years following solar maximum, and will continue to be a concern for GPS applications over the next few years (2002-2003). In order to provide timely predictions of space weather events, we have recently investigated an ionospheric warning and alert system for GPS applications. Predictive capabilities are based on space weather parameters provided by the United States Space Environment Center at NOAA. The impact of ionospheric activity on GPS performance has been quantified using several years of GPS data from the North American sector, with a focus on marine and aviation applications. We have established strong correlations between GPS performance and various ionospheric phenomena, and we are able to provide space weather predictions for GPS users up to six hours in advance.","PeriodicalId":394240,"journal":{"name":"2002 IEEE Position Location and Navigation Symposium (IEEE Cat.

Currently, WAAS employs two geostationary satellites to provide coverage to the United States. However, operational WAAS will require a redundant broadcast of WAAS throughout the US. Additional geostationary satellites will be used to provide some redundancy. Loran can serve as a cost-effective additional broadcast channel for WAAS. While additional geostationary satellites are still necessary, Loran can further augment broadcast of the WAAS message particularly in terrain, urban canyons or high latitudes. Using Loran has some appealing features. First, Loran can be modified to attain the capacity to support the WAAS message. Second, it could also provide a reversionary positioning capability in case the GPS/WAAS signal is lost due to radio frequency interference (RFI). Loran can be particularly helpful in Alaska, where terrain combined with high latitudes could block the signal from the geostationary satellite that appears low in the Alaskan sky. This paper describes the flight and ground tests of the reception of WAAS from Loran and the geostationary satellite.","PeriodicalId":394240,"journal":{"name":"2002 IEEE Position Location and Navigation Symposium (IEEE Cat.
