GSD400 GNSS Receiver
RTK accuracy & High dynamics receiver
The GSD400 OEM boards is Gran Stal’s latest generation receiver powered by the most advanced algorithms for robust and accurate positioning.
Key Features
- + 136 channels for tracking signals from GPS, BeiDou, support single BD GNSS positioning and multi-system joint positioning
- + Centimetre-level (RTK) and sub decimetre- level position accuracy
- + Support dynamic base station, used for two- dimensional orientation, three-dimensional attitude measurement
- + Long-range RTK baselines of up to 30 km
Accuracy scaleable to a centimetre
Gran Stal’s knowledge and experience in the GNSS industry ensures that the GSD400 offers you the highest possible accuracy, scaleable to a centimeter. The GSD400 GNSS receiver using the GPS dual-band, Beidou dual-band, two systems for joint positioning, with ultra-long distance RTK solution engine, adapt to harsher, long distance environment.
