About
The NewSpace Systems (NSS) magnetometer is a tri-axial sensor utilising Anisotropic Magneto-Resistive (AMR) sensors co-located with offset compensating circuitry that nulls the characteristic offset voltage of the AMR sensor, enhancing sensor performance. It provides x-, y- and z-axes magnetic field component measurements, as well as a sensor temperature measurement used for temperature compensation of the magnetic field measurement. The product includes low noise, precision processing and analogue-to-digital conversion circuitry which improves linearity and reduces drift sensitivity of the sensor head. The integrated processing circuitry and sensor head provide an accurate and stable magnetic field measurement at low power consumption. It requires a regulated 5 V DC supply, and the measured x-, y- and z-axes magnetic field components are output via a digital serial interface. Features include small size and low mass, radiation tolerant COTS construction, supply with a calibration matrix, and simple interfacing. It can be used for calculation of magnetorquer rod control torque levels, as an attitude determination sensor when used with an IGRF reference model, and as an angular rate determination sensor by comparing successive measurements. The sensor is TRL 9 with significant in-orbit heritage, developed in collaboration with the Space and Atmospheric Physics Group of Imperial College London. The sensor head first flew on the CINEMA mission, then as an integrated unit in July 2014. Since then, more than 400 units have been sold to a variety of international missions and constellation programmes, and the product is baselined on 5 constellation programmes to date.
