Overview
DGPS Smart Antenna
The MX521B delivers position accuracy better than 1 meter in DGPS/DGNSS mode when using RTCM corrections.
Beacon
Navigation authorities around the world have installed DGPS radio beacon networks that broadcast RTCM corrections. With the use of its built-in beacon demodulator, the MX521B uses these real-time corrections to deliver accurate, reliable positioning when antenna is within range of Beacon station.
RAIM
Receiver Autonomous Integrity Monitoring (RAIM) is a safety feature in the MX521B which continuously verifies the integrity of the GPS system to ascertain its accuracy and reliability. When satellite range error exceeds a pre-set limit, the CDU alerts the operator to take precautionary measures.
Interface
The MX521B features two independent NMEA compliant serial ports which are identical to MX421B-10 and MX521A DGPS smart antenna.
