Implementation of a Software-Defined BeiDou Receiver
2014Satellite-based positioning is undergoing a rapid change. Both the GPS and the GLONASS systems are being modernized to serve better the current challenging applications in harsh signal conditions. These modernizations include increasing the number of transmission frequencies and changes to the signal components.

Operation and development of BeiDou Navigation Satellite System
2015 International Association of Institutes of Navigation World Congress (IAIN), 2015The BeiDou Navigation Satellite System (BDS) is a new family member in the Global Navigation Satellite System(GNSS). It increases the usability and availability of Positioning, Navigation and Timing (PNT) around China in Asia-Pacific area, and the global users can also profit from the constellation for high accuracy.

BeiDou Time Transfer Between PTB and NTSC
The Precise Time and Time Interval Systems and Applications Meeting, 2018GNSS time transfer is a primary method for remote atomic clock comparisons. There are four global satellite navigation systems in operation, named GPS, GLONASS, Galileo and BeiDou. To guarantee the precision, the accuracy and the robustness of Coordinated Universal Time (UTC) generation, multi-techniques strategy has been encouraged by Consultative ...

Doppler-Aided Algorithm for BeiDou Position
2013Real-time GNSS positioning rely mainly on pseudorange and carrier-phase. The pseudorange is not accurate because of a lot of noise and interference in environment. High-precision carrier-phase used to smooth pseudorange. While, when cycle slip occurs, the carrier-phase measurement is bias.

Beidou communication (BeiComm) device for rescue in disaster
The First International Conference on Future Generation Communication Technologies, 2012Communication 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

GPS, GLONASS, Galileo, and BeiDou signals
2014A GNSS signal is transmitted from a satellite in order to measure the distance between the satellite and a receiver. There are four GNSS today: GPS, GLONASS, Galileo, and BeiDou. Each GNSS has its signal transmitted on specific radio frequencies. In this book we mainly consider single-frequency devices working with frequencies in the L1 band.
