Difference between WAAS, EGNOS and MSAS
{"Image DocumentName": "Difference between WAAS, EGNOS and MSAS", "Image ImageDescription": "All 3 Space-Based Augmentation Systems are compatible to. each other; so, in principle, they are the same. The main difference between DGPS and SBAS is the. calculation of the Total Electron Content (TEC) map for. ionospheric corrections. With DGPS, every single reference station, after comparing its. own position with the calculated position, transmits this. information on a certain band, as correction. For SBAS, this is different. Here, the monitoring stations do not provide single. isolated corrections, but from all stations together a correction map for a wide. area. So, every receiver corrects its position by using this data. That way, the accuracy is even better than with DGPS.
