Abstract

The requirements for precise global mapping of the Earth's vector magnetic field from a high inclination LEO satellite needs a stable and precise vector magnetometer. Equally important are the measurement of the stellar attitude of the vector sensor and establishment of the calibration by onboard comparison to an absolute scalar magnetometer. In addition, the position in orbit and the precise timing relative to the UTC is needed. Finally, the end-to-end system precision also depends on a known and controlled local satellite magnetic field.
