Our products are designed to be cost-effective and easily integrated, making them ideal for high-volume deployments and supporting the advancement of the drone and robotics industry at scale.

Tersus Advanced Positioning

Tersus Advanced Positioning (TAP) is a state-of-the-art PPP (precise point positioning) service that provides drones and unmanned systems with real-time corrections for centimeter-level accuracy. Utilizing a redundant network of satellites, global reference stations and network control centers, TAP offers global coverage with 99.99% uptime, allowing you to operate with the utmost of reliability anywhere in the world.

TAP delivers accuracy of down to 1.5 cm horizontally and 3 cm vertically, with rapid convergence times of less than 3 minutes, and frees your operations from the constraints of local base stations, CORS networks, UHF radios or cellular connections.

OEM GNSS Receiver Boards

Our RTK-capable multi-constellation GNSS receiver boards for OEMs and systems integrators provide centimeter-level positioning in a compact and low-power package, making them ideal for drone and robotics positioning and navigation applications.

Offering pin compatibility with other commonly-used GNSS boards, the BX series utilizes industry-standard command and logging formats, making them easy to integrate into a variety of new or legacy systems. We regularly update firmware and software with new and advanced features to ensure that these boards continually deliver cutting-edge capabilities

GNSS Antennas

We offer a range of lightweight multi-constellation and multi-frequency GNSS antennas in a number of form factors, featuring sophisticated tracking and anti-interference capabilities. With options for lightning-proofing and IP67-rated ruggedization, these antennas serve a variety of drone and robotics applications, including land and marine mapping and surveying, infrastructure inspection, precision agriculture, and more.

Smart RTK GNSS Receivers

Our RTK-capable smart GNSS receivers offer surveyors unprecedented levels of versatility and efficiency, featuring rugged construction for demanding field use and incorporating calibration-free tilt compensation that does away with the need to keep the survey pole upright.

All receivers include a free subscription to Tersus Caster Service (TCS), enabling them to be used as base stations that can broadcast corrections data to drones and other rovers via mobile networks.
