Data Logger Nav
The Data Logger Nav integrates GPS/GNSS with the Link’s wireless and inertial sensing functions to capture position and motion in the same recording. Its AHRS/IMU, microSD storage, BLE interface, and 700 mAh rechargeable battery provide a self-contained solution for unmanned vehicle tracking and performance analysis.
USB-C and BLE connections provide access to live measurements and recorded files. An onboard real-time clock timestamps configurable logging, with dual auto-selecting accelerometers capturing low-range motion and high-g events up to ±320g. Portable and integrated Screwdown/Strapdown cases provide a choice of installation formats.
