A novel mode of INS-aided BDS real-time high-rate and precise kinematic relative positioning between two moving platforms

open access: yesGeo-spatial Information Science
For kinematic relative positioning users between two moving platforms, limited communication bandwidth and computation ability usually cannot support real-time transmission of high-rate (≥10 Hz) BeiDou Navigation Satellite System (BDS) data.

Parameter Estimation with GNSS-Reflectometry and GNSS Synthetic Aperture Techniques

open access: yes, 2018
Aside from intentional interference, multipath is the most significant error source for Global Navigation Satellite Systems (GNSS) receivers in many operational scenarios. In this thesis, we study the multipath estimation from two different perspectives: to retrieve useful information from it using GNSS-Reflectometry (GNSS-R) techniques; and to ...
