Trimble Buffalo B1919 GNSS receiver module

Click2Contact

Trimble’s Buffalo B1919 Global Navigation Satellite System (GNSS) receiver module provides L1 frequency GPS and GLONASS, using the NMEA protocol from two serial ports and a PPS timing output. Buffalo can acquire and track GPS and GLONASS separately or use a combined solution of GPS and GLONASS. Galileo support will be available through a firmware upgrade.

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

The modules match the footprint of Copernicus II and Condor C1919 GPS receiver modules, providing an upgrade path for existing designs. The module’s 28 reflow-solderable, surface-mount edge castellations provide an interface for designs without the need for I/O and RF connectors. The receiver features powerful positioning performance in a 19 x 19 x 2.54 mm package.

The starter kit includes: a B1919 module on a carrier board, mounted in a rugged plastic enclosure suitable for mounting in a vehicle; a miniature magnetic mount antenna; three additional sample B1919 modules; an interface cable; downloadable software tools and documentation in the support tab including the Buffalo GNSS Receiver User Guide, Trimble GPS Studio application and the Trimble GPS Studio Application User Guide.
