摘要
Precise corrections with, A three-dimensional voxel model of the ionosphere based on global navigation satellite system (GNSS) data from a wide-area network of ground receivers can help resolve differential cairrier-phase ambiguities over very long baselines of hundreds of kilometers in present two-frequency systems [global positioning system (GPS) and global orbiting navigation satellite system (GLONASS)] or in planned three-frequency systems (GALILEO, Modernized GPS). A study based on simulated three-frequency data from A modified GNSS signal generator indicates that all the Phase Ambiguities could be resolved successfully more than 90% of the time. This' should be useful in surveying large areas with instruments that require Very precise geolocation (e.g;, radar or Lidar altimetry, interferometric synthetic aperture radar, interferometric sonar, etc.).
