Abstract
Processes and device configurations are provided for extracting navigation observables and navigation using low earth orbit (LEO) signals. Methods and systems described herein can detect one or more low earth orbit (LEO) satellite downlink signals, and determine carrier phase observables and Doppler observables from the downlink signals in order to determine position estimates. Processes can include determining at least one carrier phase observable from the one or more LEO satellite downlink signals, wherein determining the at least at least one carrier phase observable includes tracking a modified beat carrier phase of a sample of a detected LEO signal by performing an estimation operation for a time period and adaptive updating of measurement noise. Processes can include use of position estimates for navigation and navigation based on carrier phase tracking. Processes are also provided for determination of satellite synchronization signals (SS) from downlink transmissions using subspace detection.
