METHODS AND SYSTEMS FOR INHERENT FAST TIME TO FIRST POSITION FIX (TTFF) AND HIGH SENSITIVITY

摘要

Systems and methods for inherent fast Time To First position Fix (TTFF) and high sensitivity are described. An embodiment of a method may include interpolating a satellite position in response to a navigation message having initial conditions for satellite ephemeris data converted into Keplerian format, wherein signal fixation is maintained in response to receiving the navigation signal at least once per day.
