BeiDou Satellite Navigation System (BDS) Real-Time Orbit Determination and Accuracy Analysis

open access: closed, 2015
BeiDou Satellite Navigation System requires accurate real-time orbit products to support high precision real-time PNT services. Currently, BDS treats broadcast ephemeris as real-time orbits, whose precision is poor (at the level of meter). Based on characteristics of stations distribution and satellites constellations structure of BDS, this paper ...

An Offline Signal Quality Monitoring Software of BeiDou Navigation Satellite System (BDS) with New Signal Plan Based on Software Defined Radio (SDR) Receiver

open access: closed2013 Third International Conference on Instrumentation, Measurement, Computer, Communication and Control, 2013
Multi-band, multi-service and multi-modulation are new trends of GNSS development. Since novel modulation types like BOC/MBOC and multiplex techniques like (POCET, Interplex) of navigation signals have been utilized [1], the composite navigation performance is indeed improved.

Evaluation of Multisignal and Multiorbit Multipath Reflectometry of BeiDou Navigation Satellite System

IEEE Geoscience and Remote Sensing Letters, 2023
Global navigation satellite system multipath reflectometry (GNSS-MR) has been validated for the estimation of water level. More satellites and signals would aid the accuracy and sampling rate of GNSS-MR.
