Accuracy of geodetic solutions based on Doppler measurements of the Navstar global positioning system satellites
- 62 Downloads
A dual frequency Doppler receiver is being developed by the Naval Surface Weapons Center for possible use by the Defense Mapping Agency in determining the position of ground sites based on observations of NAVSTAR Global Positioning satellites. Preliminary analysis indicates that the relative position of widely separated sites can be computed to better than 40 cm accuracy at eight hour intervals. A number of possibilities are being explored to improve the accuracy to the sub-decimeter level.
