ER-200 is section of high performance GPS / GLONASS combo satellite receive board, with GPS, GLONASS and GPS + GLONASS three positioning mode.

In order to ensure the positioning precision of the optimal, three positioning and automatic mode switching, also by setting a fixed positioning mode can achieve this. Received in the carrier phase smoothing pseudo range to improve the precision of pseudo range measurement, improve the positioning accuracy; using pipelined fast parallel processing algorithms, satellite capture and recapture fast; By one order velocity loop, the second-order acceleration loop and the third order and acceleration loop dynamic control to achieve high dynamic precision stability to meet the needs of the positioning of the carrier in a variety of dynamic environments.
