Inertial Navigation Module for Embedded Platforms
A configurable inertial processing module that combines motion sensing, time synchronization and embedded fusion for navigation, stabilization and platform-state estimation.
Navigation performance depends on the entire chain: sensor selection, mechanical placement, temperature behavior, timing, calibration and the fusion model. Treating the IMU as an isolated component usually leaves avoidable errors at system level.
The Alvexis approach integrates inertial sensing with embedded processing and platform interfaces. The module can serve as a navigation aid, motion-reference source or synchronized input to a wider perception stack.
