Trimble ProPoint® positioning engine

Trimble's new positioning engine

Now available on Trimble’s BD/BX/AX products that utilize Maxwell™ 7 technologyTrimble ProPoint® positioning engine is the fifth generation high-precision positioning engine from Trimble that is engineered to provide position and orientation data from the fusion of GNSS signals, globally accessible high-accuracy correction services and measurement data from a variety of sensors. It leverages the latest developments in GNSS signal infrastructure and Trimble’s high-precision receiver hardware to deliver improved positioning performance in challenging environments. It also contains dynamic models of specific application movements allowing it to filter out unexpected dynamic movements, such as with a bulldozer sliding sideways during operation, for improved accuracy.

Advantages and key value drivers:

Improved accuracy

  • Improved RTK and Trimble RTX® performance in typically challenging environments where satellite line of sight can be impaired, such as under tree canopy and highway overpasses and in dense urban areas

  • Sensor fusion using tighter integration of GNSS and IMU (and new technologies in the future) to provide continuous position and orientation solution

  • Dynamic models tuned to specific applications such as automotive vs off-road vs marine for enhanced performance

Increased availability

  • Independent tracking loop to enable tracking of L2C, L5 signals in the solution if L1 is jammed

  • Robust GNSS performance under harsh conditions such as canopy and urban environments

  • Reduced convergence times (<1 min in RTX-Fast regions) by utilizing multi-constellation signals from GPS, Galileo, GLONASS, BeiDou and QZSS

Better integrity

  • Advanced signal filtering and error modeling means better protection against jamming, spoofing and multipath interference

  • Improved satellite health reporting to better handle unforeseen constellation outages

  • Incorporation of Galileo NeQuick ionospheric model results in better resiliency

Enhanced constellation support

  • Implementation of all open BeiDou3 signals in RTK and RTX solution

  • Support for E6 data channel on Gen-II QZSS satellite signals

  • NAVIC support for correction formats
