Millimeter-level accuracy
The THA‑703A delivers outstanding millimeter‑level positioning accuracy to meet the most demanding precision tasks. Supported by stable phase center performance and advanced D‑QHA technology, it provides highly consistent and reliable positioning data, ensuring professional results for surveying, mapping, and high‑precision UAV operations. It maintains stable tracking even in challenging environments with partial sky visibility, delivering continuous high‑precision output for mission‑critical applications such as power line inspection, aerial surveying, and infrastructure mapping.
Compact size and easy to install
Excellent satellite reception
The THA‑7603A uses advanced D‑QHA technology to greatly enhance low‑elevation satellite tracking and capture signals more efficiently. It locks onto visible satellites steadily even in partially blocked environments like tree lines, urban canyons, or near power facilities. With high gain, low axial ratio, and omnidirectional coverage, it maintains consistent signal strength and continuity, ensuring stable positioning output and high availability for surveying, UAV patrol, and critical precision applications.
