The BD992-INS is a dual-antenna receiver with an integrated inertial navigation system. It is a robust navigation system that supports position and orientation at high update rates.
GNSS AND INERTIAL TIGHT
Taking advantage of Trimble’s expertize in both GNSS and Inertiel technology the Trimble BD992-INS module has been designed for applications requiring continuous centimeter accuracy in a compact package. By integrating inertial sensors on the same module, robust high accuracy positions and orientations are produced in all environments.
Description en anglais.
The Trimble BD992-INS supports triple frequency for the GPS, GLONASS, BeiDou and Galileo constellations. As the number of satellites in the constellations grows the BD992-INS is ready to take advantage of the additional signals. This delivers the quickest and most reliable RTK initializations for centimeter positioning. For applications that do not require centimeter accuracy the BD992-INS integrated GNSS-Inertial engine also delivers high accuracy GNSS, DGNSS positions in the most challenging environments such as urban canyons.With the latest Trimble Maxwell™ 7 Technology, the BD992-INS provides :
With the option of utilizing OmniSTAR or RTX services, the BD992-INS delivers varying levels of performance down to centimeter level without the use of a base station.
The Trimble BD992-INS integrates the latest in precision inertial sensors in a compact package. With the BD992-INS you are buying a robust navigation solution, not just a GNSS receiver. Key features include :
The Trimble BD992-INS 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. An intuitive 3D interactive graphical web page allows easy input of lever arms. Dynamic and graphic models for various vehicle types can also be selected. 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 passwordupgradeable, allowing functionality to be upgraded as your requirements change.
