Trimble (Marine) Trimble Marine GNSS / INS

Dual antenna GNSS receiver with optional INS

The BX992 is a dual antenna GNSS receiver offering precise heading capability and multifrequency
support for all known constellations. Additionally, with support for MSS L-Band OmniSTAR, Marinestar
or RTX services, the BX992 delivers location without the use of a base station.
The optional Inertial navigation system technology has been designed for applications requiring continuous centimeter accuracy, atititude, heave and heading.

The Trimble BX992 supports multi-frequency for the GPS, QZSS, GLONASS, BeiDou and Galileo constellations. As the number of satellites in the constellations grows, the BX992 is ready to take advantage of the additional signals. This delivers the quickest and most reliable RTK initializations for precise positioning. For applications that do not require centimeter accuracy, the BX992 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 BX992 provides: 

The Trimble BX992 was designed for easy integration and rugged dependability. Customers benefit from the Ethernet connectivity available on the board. 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 an 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 password upgradeable, allowing functionality to be upgraded as your requirements change.

Key Features:

► Optional upgrade for onboard inertial sensor package integrated with GNSS for precise position, orientation and heave

► Flexible RS232, USB and Ethernet interfacing, allowing high speed data transfer and configuration via standard web browsers

► Scalable accuracies up to centimeter level position accuracy

► Environmentally sealed IP67 with enclosure built to withstand harsh environments

► Small form factor makes it ideal for installation and use in applications where space is limited

► LED indicators on the receiver provide immediate performance feedback for Power, RTK Corrections, and satellite tracking status

► Trimble RTX and Marinestar Support
