- Abstract
- WA-DGNSS provides the correction data and integrity information to the user via geostationary satellite. WA -DGNSS comprises Wide Area Reference Station, Master Station and User. Wide area reference station (WRS) receives data from the GNSS satellite, performs quality monitoring of decoded navigation data, and sends the correction data to wide area master station (WMS) via terrestrial communication network. WMS processes the data collected from the WRS, and uplinks the calculated correction data and integrity information to the geostationary satellite (GEO). GEO satellite downlinks the correction data to the users such as aerospace, marines, land applications etc for accurate and reliable positioning. Preliminary design results of WRS software are described in this paper, and it provides flexibilities in terms of modeling as well as system by taking modular software design approach.
