TruPrecision software simplifies the user interface to the antenna’s GNSS receiver and provides extras such as logging tools, GNSS signal strength graphs and tools for sharing RTCM between base and rover antenna pairs across the internet. It also includes a 60-day complimentary access to u-blox’s PointPerfect GNSS Augmentation Service, with an easy process for quickly applying the corrections to your SDK antenna.

TW5794 SDK includes:

  • Calian TW5794 Smart GNSS Precise Heading antenna with USB
  • Calian TruPrecision Application for Software Development and Verification
  • 60-day trial subscription to the PointPerfect augmentation service
  • Ordering Information: 33-TP5794SDK-1 TW5794 SDK

The TruPrecison SDK application provides an autonomous connection to stream PointPerfect IP corrections and decryption keys to a TW5794 Smart Antenna via a USB connection, which also provides a Virtual COM Port to allow customers to connect their existing applications to the Calian TW5794 Smart GNSS Precise Heading Antenna high precision “corrected” position data output. The position data may be either NMEA or UBX formatted messages. ROS2® Drivers are available to integrate with ROS2® open framework projects.
