The Magnetometer is a unit used in LEO satellites to provide coarse azimuth direction, by data processing of the three measured orthogonal components of the earth magnetic field.
The magnetometer has been developed and been produced as part of a family of products dedicated for the Attitude Control System of satellites, in the framework of TAMAM’s Division long term activities as part of the inertial navigation domain.
The product is based on technological assets of magnetic design and material engineering developed for gyros, accelerometers, synchros and resolvers, electrical motors and magnetotorquers.
The leading product was space qualified and flight proven in the frame of the remote sensing satellites OFEQ and the scientific micro-satellite TECHSAT.
The Magnetometer contain the following sub-assemblies: (1) A sensor unit which consists of coils wound on high permeability ferromagnetic cores. (2) An electronic unit, which consists of an oscillator that excites the sensors and three control-capture-loops that process the sensor signals and provide three output analog signals. (3) The functional module is mounted in an aluminum case.
