New Observational Techniques and Precise Orbit Determination of Artificial Satellitesioning System (GPS), offer alternatives, including kinematic techniques which require no modeling of the satellite forces, or only rudimentary models. This paper will describe the various techniques and illustrate the accuracies achieved with current satellites, such as TOPEX/POSEIDON, GPS/MET and the expectations for some future satellites.作者: CHASE 時(shí)間: 2025-3-23 15:46
