Permanent Link to BeiDou Precision Nav Will Receive GPS, GLONASS, Galileo Signals
A senior Chinese government space official on Feb. 5 said precision-navigation user receivers in China will be fitted with chipsets receiving satellite signals from BeiDou, GPS, GLONASS, and Galileo, according to Space News. The move could accelerate the trend among navigation chipset and receiver makers to build gear for multi-constellation reception, and at the same time undermine regional measures to promote one system over others.
Chen Zhi, deputy chief designer of the China Aerospace Science and Industry Corp., said China’s early deployment of satellite navigation receivers for precision agriculture already feature multi-constellation GPS-Beidou receivers.
The United States and European Union have signed World Trade Organization agreements for their constellations, GPS and Galileo. China and Russia are not part of the agreements.
