Mitigating Ephemeris Uncertainty in LEO Geolocation: An Uncertainty-Aware Weighted Least Squares Method via Dual-Satellite Cumulative TDOA/FDOA Fusion

open access: yesIEEE Open Journal of the Communications Society
Accurate and robust localization of non-cooperative emitters is a cornerstone capability for modern low Earth orbit. To mitigate localization degradation caused by satellite ephemeris errors, this paper proposes a multi-epoch dual-satellite geolocation ...

Sensor network distributed computation for Direct Position Determination

open access: yes, 2012
—Classical localization systems based on TDOA/FDOA use a two-stage estimation approach. In the first stage, pairs of sensors share data to estimate TDOA/FDOA. Then, the extracted TDOA/FDOA measurements are used to estimate the emitter location.

Data compression for complex ambiguity function for emitter location

open access: yes, 2010
The Complex Ambiguity Function (CAF) used in emitter location measurement is a 2-dimensional complex-valued function of time-difference-of-arrival (TDOA) and frequency-difference-of-arrival (FDOA).
