| Abstract: | A new method for resolving the carrier-phase integer ambiguity in Global Navigation Satellite Systems (GNSS) is presented:
the MOdified Cholesky factorization for Ambiguity (MOCA) resolution. The characteristics and features of this method are described
and results obtained using a software simulator and an emulator are presented to validate its efficiency. The results are
then compared to those obtained using another existing method and good performance of the MOCA method in new GNSS systems
is shown. Furthermore, the proposed method yields accurate results even when short time spans are used or when there are poor
estimations of measurement error, making it immune to non-ideal conditions and ultimately a practical solution for real applications. |
