Summary
The NSS tri-axial magnetometer utilizes Anisotropic Magneto-Resistive (AMR) sensors which are co-located with offset compensating circuitry. The offset compensating circuitry nulls the characteristic offset voltage of the AMR sensor, which enhances the sensor performance. The sensor provides x-, y- and z-axes magnetic field component measurements, as well as a sensor temperature measurement which is used for the temperature compensation of the magnetic field measurement.
Applications
- Can be used for the calculation of magnetorquer rods control torque levels
- Attitude determination sensor when used with an IGRF reference model
- Angular rate determination sensor by comparing successive measurements
Key features
- Small size and low mass
- Radiation tolerant COTS
- Supplied with calibration matrix
- Simple to interface
Flight heritage
The sensor head first flew on the CINEMA mission and then as an integrated unit in July 2014. Since then, >240 units have been delivered to a variety of international missions and constellation programs. To date, this product is based on 5 constellation programs.
