BX992
Multi-frequency GNSS receiver
Robust, high accuracy positioning and orientation

The Trimble Marine BX992 is a dual-antenna multi-frequency GNSS receiver with precise heading capability. The Marine BX992 comes standard with GPS, QZSS and GLONASS installed. The BX992 provides scalable precisions up to centimetre accuracy position in a compact package, supporting reliable GPS positioning in demanding marine and mobile applications.
By integrating the latest GNSS technology from Trimble, it provides robust high accuracy positions and orientation. It offers MSS L-Band support for Marinestar or Trimble RTX services so the BX992 delivers precise position without the use of a base station. Within SITECH’s wider Trimble technology solutions, the BX992 supports applications where accurate positioning, heading and dependable field performance are critical.
Dual Antenna Input
The dual antenna input provides precise heading compared to single antenna systems which have difficulty determining position relative to the object of interest, especially when dynamics are low. This makes the Trimble BX992 suitable for marine construction, vessel positioning and workflows where GNSS technology is used to support both position and orientation.
Rugged, But Flexible Interface
The BX992 offers easy integration and dependability. The BX992 is built to perform reliably and rigorously in harsh environmental conditions. For teams working across broader site measurement and positioning workflows, SITECH also supports complementary technologies such as Loadscan solutions and Trimble solutions for construction and site productivity.
