1.    Descriptions

Along with the independent research and development of BD2 satellite navigation system gradually improved in our country, and aimed at the needs of users, high-performance Satellite Navigation Receiver UGC300 is researched. UGC300 is fully compatible with JNS100 plate type of satellite receiver, JAVAD company, also can be replaced directly. Adopt GPS+GLONASS+BD2 Three system four frequency high dynamic calculating model, it can realize GPS-L1, GLONASS-L1, BD2-B1, BD2-B3 Single or assemble any system of integrated navigation positioning system.

Based on the excellent hardware structure and software algorithm of the circuit board, the highest positioning decoding output frequency is 100Hz. Besides, the circuit board has the function of BD2 B3 frequency point C/A code guide P code capture, this function improves the circuit board's anti-interference performance, makes the positioning more safe and reliable. It supports every single or multi-system's combination, at the same time, calculating and output positioning results respectively. This way can provide the flexible and reliable positioning information for user.
