Product overview
The Hi-Target UAV-381-PPK is an airborne PPK positioning unit for UAV aerial photogrammetry. It observes GNSS signals across all constellations and supports a joint solution using three satellite systems. Camera shutter synchronization records the precise time and position of exposure, supporting centimeter-level photogrammetric accuracy. Its PPK workflow reduces ground control requirements: the stated reduction is 80%, with a separate operating range of 75%–85% for aerial survey work. These functions support survey capture with fewer ground control points.
The airborne unit weighs 77 g net, with total weight below 100 g, giving integrators a lightweight positioning component to accommodate aboard a survey UAV. Type-C multiplexing reduces connector count, while double-sided LED indicators reduce installation restrictions. The unit supports direct avionics connection, consumes 2 W and accepts 6–30 V DC power. Data updates are 5 Hz as standard, with 20 Hz also specified; the stated flight operating radius is 20 km.
