Method and apparatus for wide area augmentation system having GEO uplink subsystem with enhanced clock steering |
摘要 |
A system to provide navigation signals to a space vehicle includes an uplink system for a geostationary earth satellite having clock steering derived from smoothed receiver clock error, long term clock error average, and long term clock offset average information. A proportional-integral-differential controller can be used to generate clock adjustment commands to a frequency standard clock.
