Tallysman Adds The TW5394/TW5794 Smart GNSS Precise Heading Antenna To Its Line Of Smart GNSS Antennas, Targeting Robotics And Drone Markets

Focusing on the burgeoning market for precise heading in unmanned vehicles and robots, Tallysman Wireless is introducing the TW5394 (fixed mount … TW5794 surface mount) Smart GNSS Precise Heading Antenna, which supports moving-base RTK precise heading and PPP-RTK high precision location capability via L-Band. The TW5394/5794 combines Tallysman Wireless’ multi-band Accutenna technology with u-blox’s Zed-F9P GNSS and NEO-D9S L-Band receivers. The integrated L-Band receiver allows operators to deploy an augmented position solution when operating outside of terrestrial communications range by receiving PPP-RTK augmentation directly from the satellite. Deployment of two TW5394/5794 devices as a moving base + rover antenna pair enables a precise heading solution, yielding 0.4º heading accuracy when deployed with a minimum 1-meter baseline. Communication interface options include USB or RS-232 to the host system.

TW5394/5794 employs Tallysman’s eXtended Filtering, which mitigates near-band and out-of-band interference sources such as LTE signals and their harmonics, including the planned Ligado service in North America, enabling operation in the most challenging urban deployments.

The TW5394/5794 builds on Tallysman’s 10+ years of integrating its antenna technology with receiver technology in an easy-to-deploy package that mitigates common GNSS engineering challenges.

Tallysman has developed ROS2 drivers, in conjunction with InDro Robotics (https://indrorobotics.ca), for fast and reliable integration of Tallysman Smart GNSS antennas into robotic applications. These drivers enable integrators to easily utilize Tallysman High Precision Smart GNSS Antennas to provide high accuracy location information, including latitude, longitude, speed, precise heading, and quality of fix.

Software Development Kits are available to complement the TW5394/5794, the 33-5394SDK-1 (for the TW5394) and the 33-5794SDK-1 (for the TW5794), which bundle a TW5394 or TW5794 antenna respectively (USB versions) with Tallysman’s TruPrecision configuration/evaluation software and 60 days of complimentary u-blox PointPerfect PPP-RTK augmentation service.
