摘要： Data from GPS satellites within the field of view of a ground station are retransmitted to LEO satellites, such as Iridium satellites, and cross-linked if necessary before being transmitted to a user. The user is then able to combine the fed-forward data with data received directly from GPS satellites in order to resolve errors due to interference or jamming. Iridium and data aiding thus provides a means for extending GPS performance under a variety of data-impaired conditions because it can provide certain aiding information over its data link in real time.
摘要翻译：来自地面站视野内的GPS卫星的数据被重新发送到诸如铱星等LEO卫星，并且如果需要，则在传送给用户之前进行交联。用户然后能够将前馈数据与从GPS卫星直接接收的数据组合，以便解决由于干扰或干扰而导致的错误。因此，铱星和数据协助提供了在各种数据受损条件下扩展GPS性能的手段，因为它可以实时提供其数据链路上的某些辅助信息。

摘要： A method, system, and apparatus are disclosed for multipath isolation through the combined use of antenna diversity and frequency diversity. In particular, the present disclosure utilizes antenna diversity and frequency diversity to combat the deleterious effects of reflected signals on the positioning accuracy of satellite navigation systems. In at least one embodiment, the present disclosure uses two antennas and two frequencies for operation with a satellite navigation system. The present disclosure segregates the antennas and frequencies into two classes: references and monitors. The reference measurements are used for estimating the state of the vehicle, and the monitor measurements are used to detect faults that might degrade the reference estimation. Thus, the present disclosure enables an improvement in the positioning error experienced by roving users in downtown and indoor environments. Applications include positive train control, aircraft surface guidance, marine craft navigation in canals and ports, as well as automotive lane keeping.
