Beidou communication (BeiComm) device for rescue in disaster

The First International Conference on Future Generation Communication Technologies, 2012
Communication during the disaster is a difficult issue. The disaster may be natural like tsunami, hurricane, cyclones or man-made like terrorist attack, massive power failure or wartime scenario. The high bandwidth supporting technology is evolving very fast, leading us from 4G/LTE to 5G/cognitive devices' regime. Unfortunately all these technology are

Quantization Effect on BeiDou Signal in Jamming Environment

Proceedings of the 2020 3rd International Conference on Geoinformatics and Data Analysis, 2020
The radio frequency interference has become a rising problem to the signal of BeiDou Navigation Satellite System (BDS). Many researchers have analyzed the impact of jammer on the loss of Signal to Noise Ratio (SNR) of receivers after post-correlation.

Tests of Galileo and BeiDou links for UTC

2019 Joint Conference of the IEEE International Frequency Control Symposium and European Frequency and Time Forum (EFTF/IFC), 2019
Time links used in UTC computation are based on Global Navigation Satellite Systems and on the Two Way Satellite Time and Frequency Transfer technique. For GNSS, GPS forms the basis of all links and GLONASS has been also used. The other global systems Galileo and BeiDou have reached operational status and we study in this paper how they could ...
