The BeiDou navigation satellite system

2014 XXXIth URSI General Assembly and Scientific Symposium (URSI GASS), 2014
The BeiDou Navigation Satellite System (BDS) is a global navigation satellite system to be developed independently by China. It will provide positioning, navigation, and timing services with a global coverage by 2020. It can be used for transport, weather forecast, fishing, forestry, telecommunications, hydrological monitoring, and mapping. The service

Progress of BeiDou time transfer at NTSC

Metrologia, 2018
Time transfer using global navigation satellite system (GNSS) is a primary method of remote atomic clock comparisons. As of today, there are four operational GNSS systems, namely GPS, GLONASS, Galileo and BeiDou Navigation Satellite System (BDS or BeiDou). All of them can continuously provide position, navigation and time services.

Doppler-Aided Algorithm for BeiDou Position

2013
Real-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.

Measurements of Beidou Antenna for Iridium Communication

2019 IEEE 2nd International Conference on Electronic Information and Communication Technology (ICEICT), 2019
With the increasing demand for large-scale data transmission and data security in deep sea observation and detection, Iridium and Beidou dual-mode communication has become the main approach in the field of China’s ocean observation and detection. However, the size and weight of the two antennas are not easy to reduce, which presents a challenge to the ...

BeiDou-1 Signal Simulation for Passive Location

2012
As BeiDou-1 (BD-1) receivers are widely applied in communication, power and defense construction areas nowadays, the technology of assessing receivers based on simulators attracts more attention. However, due to the particular retransmission characteristics in BD-1 and the lagging research on relatively signal simulator, the simulator without ephemeris

Viterbi Decoder Design of Beidou RDSS Receiver

Applied Mechanics and Materials, 2013
Firstly, the convolutional encoding with constraint length of 7 is used as the channel coding scheme in Beidou RDSS system. In addition, in receiver design Viterbi Decoder serves as the decoder of convolutional encoding. Finally, the optimized design of hardware construction in traditional Viterbi compared with that in decoder is introduced to reduce ...

Characteristics Analysis of BeiDou Melbourne-Wübbena Combination

2015
Melbourne-Wubbena (MW) combination, which has characteristics of geometry-free and ionosphere-free (first-order), has been often used for cycle slip detection and facilitating ambiguity resolution in GNSS dual-frequency data processing. The constellation of BeiDou Navigation Satellite System (BDS) is different from that of GPS.
