With a focus on the fast-growing market for precise heading in robotics and unmanned vehicles, Calian GNSS Ltd. has introduced the TW5394/TW5794 (fixed mount/surface mount) Smart GNSS Precise Heading Antenna.
This antenna supports moving-base RTK precise heading and PPP-RTK high precision location capability via L-Band. The TW5394/5794 combines Calian’s 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 Calian’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 Calian’s 10+ years of integrating its antenna technology with receiver technology in an easy-to-deploy package that mitigates common GNSS engineering challenges.
Calian has developed ROS2® drivers, in conjunction with InDro Robotics, for fast and reliable integration of Calian Smart GNSS antennas into robotic applications. These drivers enable integrators to easily utilize Calian 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 antenna, the 33-5394SDK-1 (for the TW5394) and the 33-5794SDK-1 (for the TW5794), as well as 60 days of complimentary u-blox PointPerfect® PPP-RTK augmentation service.
