BDS Long-Term Almanac Fitting Arc Length Design for Autonomous Navigationmode, in this paper, without changing the almanac model, we propose the scheme of different fitting arc length for different types of satellites. Considering position fitting maximum error, fitting stability and satellite storage resources on-board, the optimal fitting arc length for long-term alman

Strategy Analysis of Anchorage Station in Distributed Autonomous Orbit Determination for Beidou MEO orbit determination strategy of all constellations is studied. The distributed autonomous orbit determination algorithm under the constraints of long-term forecast ephemeris is deduced, and the relationship between anchorage station setting strategy and orbit determination accuracy is analyzed. The

Preliminary Evaluation on the Precision of the BDS-3 Global Ionospheric Modelbal ionospheric model, called BDGIM. Single-frequency users can use the BDGIM along with nine ionospheric parameters broadcasted in the navigation message to perform ionospheric correction. This paper analyzes the deficiency of the current BDS and GPS Klobuchar models, and then by using the high pre

Research on Multi-GNSS Wide-Lane FCB Estimation Method Based on MGEXfractional cycle biases products are urgently needed. In this contribution, the ambiguity resolution in Multi-GNSS is deduced in detail based on the observation and precise products provided by multi-GNSS Experiment (MGEX). Meanwhile, a Multi-GNSS wide-lane FCB product estimation method is proposed.
