The specific coordinates of satellites can be calculated based on the BeiDou
satellite ephemeris files.
Named after the Chinese word for the Big Dipper star pattern, the Beidou
system is now in its third stage and is capable of providing navigation and positioning services in different geographical regions.
Just months before Beijing unveiled the Belt and Road project in 2013, it signed an agreement with Pakistan to build a network of satellite stations inside the country to establish the Beidou
Navigation System as an alternative to the American GPS network.
Named after the Chinese term for the Big Dipper, the BeiDou
system started serving China in 2000 and the Asia-Pacific region in 2012.
The 28th and 29th satellites in the domestically developed Beidou
Navigation Satellite System, one of the nation's largest space programs, were lifted atop a Long March 3B carrier rocket at the Xichang Satellite Launch Center.
The main objective of this study is utilizing selected indicators provided by the G-Nut/Anubis to analyze a long-term quality of BeiDou
and GPS observations.
The receiver mask angle was set to 15[degrees] and it could receive signals from the following GNSS constellations: GPS, QZSS, and BeiDou
. Since the simulation only considers a satellite visible when it has direct LOS to the receiver, multipath signals need to be mitigated from the observed data.
Moreover, the receiver's clock bias and drift errors of GPS and BeiDou
can be modeled as
The Thuraya XT-PRO DUAL also boasts of advanced navigation capabilities through GPS, BeiDou
, Glonass and Galileo.
It has a BeiDou
Navigation Satellite System that remotely connects Mobile Apps and Yadea Z3.
The two countries also agreed to synchronize their satellite navigation system, GLONASS and Beidou
, Kashin informed.
Atualmente, novos sistemas globais de posicionamento por satelites estao sendo desenvolvidos, tais como o Galileo, pela Uniao Europeia, e o BeiDou
, pela China, porem apenas o GPS e o GLONASS encontram-se plenamente operacionais.
