Aims & scope • Validate a recently developed real-time estimation technique for the temperature time derivative inside a navigation-grade inertial system. • Overcome specific challenging aspects: measurement quantization, error’s time correlation, wide time domain range, real-time implementation. • A parametric model for a short-term temperature approximation and specific estimation algorithm to determine the model parameters • Numerically stable finite-impulse-response modification of a conventional Kalman filter applied only on temperature sensor updates. • Exhaustive analysis of performance over a hundred of experiments with different temperature variation patterns.
