The CKG4-B3 anti-interference BDS satellite positioning receiver is used to receive satellite navigation signals at BDS B3 frequency point and process them accordingly, providing raw observation data as well as position, velocity, time and other information for the flight control components of the maneuvering carrier. It has strong anti-interference ability and meets the application requirements in complex electromagnetic environments.
a) The receiver has self checking function;
b) Capable of providing initial time synchronization and loading ephemeris through RS-422;
c) Capable of utilizing the civilian code and long code signals of BDS B3 frequency for timing and three-dimensional positioning;
d) Capable of using RS-232 to load all programs online;
e) Capable of outputting pseudo range, pseudo range rate and other information in the specified format to the flight control components through ARINC-429 for tight combination navigation function;
f) Capable of suppressing strong interference signals and improving the system's anti-interference ability through space-time adaptive anti-interference algorithms.
