RTK+IMU Card | P684-D

Full constellation multifrequency RTK+IMU Card

Anti-occlusionHigh continuityHigh reliabilityHigh frequency

P684-D is a new generation of all-constellation, multi-frequency RTK + IMU inertial navigation board independently developed by EYESTAR, which supports dual-antenna positioning and orientation technology. The board has a built-in high-precision gyroscope and accelerometer, and uses a complete GNSS/INS integrated navigation algorithm engine to ensure high continuity, high integrity and high frequency dynamic positioning results even in the environment where the GNSS signal is rejected or the signal is blocked.

Features

High precision, small size, ultra-low power consumption (as low as 140mW)
Support system-wide full-frequency point dual-antenna positioning and orientation technology, and support modern signal systems such as BDS-3 and Galileo
Using the latest self-developed algorithm engine and IMU array technology (IMU Array), it provides high-precision vector pose information in real time, and calmly addresses the challenge of occlusion.
Support 100Hz data output, which can meet the needs of high-speed motion carriers such as aircraft, high-speed rail, and automobiles
