Data-Driven Generalized Integer Aperture Bootstrapping for Real-Time High Integrity Applications [PDF]
A new method is developed for integer ambiguity resolution in carrier-phase differential GPS (CDGPS) positioning. The method is novel in that it is (1) data-driven, (2) generalized to include partial ambiguity resolution, and (3) amenable to a full ...

Fourier Ambiguity Resolution for Carrier-Phase GNSS
Applied SciencesIn this contribution, we introduce the concept of Fourier ambiguity resolution. We show how it is rooted in the principle of integer equivariant (IE) estimation and in its periodic representation.
