The Trimble BD992 dual-antenna GNSS system is a single board solution for precise position and heading. Heading derived from dual-antenna GNSS measurements help overcome issues typically seen in single antenna GNSS systems such as difficulty determining where the antenna is positioned relative to the vehicle and object of interest or drifting external sensors caused by static.

The Trimble® BD992 GNSS system is a single board solution for precise position and heading. Single antenna GNSS systems have difficulty determining where the antenna is positioned relative to the vehicle and object of interest, especially when dynamics are low. External sensors can be used to augment this however these tend to drift when static. Heading derived from dual-antenna GNSS measurements overcomes these issues and is now economically the right choice.
The Trimble BD992 supports triple frequency for the GPS, GLONASS, BeiDou and Galileo constellations. As the number of satellites in the constellations grows the BD992 is ready to take advantage of the additional signals. This delivers the quickest and most reliable RTK initializations for centimeter positioning. With the latest Trimble Maxwell™ 7 Technology, the BD992 provides :
With the option of utilizing OmniSTAR or RTX services, the BD992 delivers varying levels of performance down to centimeter-level without the use of a base station.
The Trimble BD992 integrates the latest in precision inertial sensors in a compact package. With the BD992 you are buying a robust navigation solution, not just a GNSS receiver. Key features include:
The Trimble BD992 was designed for easy integration and rugged dependability. Customers benefit from the Ethernet connectivity available on the board, allowing high speed data transfer and configuration via standard web browsers. USB, CAN and RS-232 are also supported. Just like other Trimble embedded technologies, easy to use software commands simplify integration and reduce development times
Different configurations of the module are available. These include everything from a DGPS L1 unit all the way to a four constellation triple frequency RTK unit. All features are password upgradeable, allowing functionality to be upgraded as your requirements change.

1 Trimble BD992 is available in a variety of software configurations. Specifications shown reflect full capability.
2 Developed under a License of the European Union and the European Space Agency.
3 May be affected by atmospheric conditions, signal multipath, and satellite geometry. Initialization reliability is continuously monitored to ensure highest quality.
4 1 sigma level, when using Trimble Zephyr 2/3 antennas, add 1 ppm to RTK Position accuracies.
5 At maximum output rate.
6 GPS only and depends on SBAS System performance. FAA WAAS accuracy specifications are <5 m 3DRMS.
7 Typical observed values.
8 No previous satellite (ephemerides / almanac) or position (approximate position or time) information.
9 Ephemerides and last used position known
10 As required by the U.S. Department of Commerce to comply with export licensing restrictions.
11 Dependent on appropriate mounting/enclosure design.
12 Input only network correction
13 There is no public GLONASS L3 CDMA. The current capability in the receivers is based on publicly available information. As such, Trimble cannot guarantee that these receivers will be fully compatible.
14 Trimble RTX and OmniSTAR accuracies depend on correction service chosen. Trimble CenterPoint RTX provides <4cm horizontal accuracy 95% of the time with initializations of less than 30 minutes.
15 Also available in configurations with RTK accuracies limited to 10 and 30 centimeters
Garantie : 2 ans.
