TRIMBLE Bison BN1919 GPS+DR, three-axis gyro and three-axis accelerometer 

The Bison BN1919 module is a world class DR + GNSS module that contains a microprocessor and an integrated GNSS receiver capable of using GPS and GLONASS constellations, combined with a three-axis gyro and three-axis accelerometer to provide a positioning solution even in the harshest of automotive environments. Together, these elements allow the Bison module to easily determine the complete vehicle dynamics. The Bison GNSS engine can acquire, track, and use GPS and GLONASS satellites anywhere in the world.

The Bison module has an onboard low-noise amplifier (LNA) that is compatible with both active and passive antenna implementations. It includes an onboard RTC and TCXO and also has built-in antenna detection for open and short circuit conditions.

The Bison BN1919 module features powerful positioning performance in a 19.0 mm x 10.0 mm x 2.54 mm package. The module's 28 reflow-solderable surface-mount edge castellation provide an interface for your design without the need for costly I/O and RF connectors.

Other key features:

• Supports NMEA 0183 protocol
• Continuous position outputs in tunnels, parking garages and on lower bridge decks.
• Instantaneous and accurate positions in deep urban canyons and dense forests.
