The BD940 from Trimble is a Triple-Frequency GNSS Receiver that is designed for applications requiring centimetre accuracy in a very small package. It supports both triple-frequency from the GPS and GLONASS constellations and dual-frequency from BeiDou and Galileo. This receiver uses the latest Trimble Maxwell™ 7 technology with advanced RF spectrum monitoring and analysis. It has 336 tracking channels and delivers quick and reliable RTK and RTX initializations for centimetre positioning. For applications that do not require centimetre accuracy, the BD940 contains an advanced Kalman filter PVT engine that delivers high accuracy GNSS, DGNSS positions in the most challenging environments.
The BD940 receiver supports Fault Detection and Exclusion (FDE) and Receiver Autonomous Integrity Monitoring (RAIM) for safety-critical applications. It has Ethernet connectivity on the board that allows high speed data transfer and configuration via standard web browsers with support for USB and RS-232 interfaces. This receiver is available in a module that measures 51 x 44 x 7 mm with a complete drop-in, solder-down module to ensure the GNSS signals are protected from the sources of EMI on the host platform. It also significantly reduces radiated emissions which speeds compliance certification and time to market. It requires a DC supply of 3.3 V.
