    Magnetometer

    The design of the tri-axial magnetometer uses 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 and enhances the sensors 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.

    Ideally mounted outside the spacecraft atthe end of a rigid boom the NewSpace magnetometer includes low noise, precision processing and analogue-to-digital conversion circuitry; all of which improves the linearity and reduces the drift sensitivity of the sensor head. The integrated processing circuitry and sensor head provides an accurate and stable magnetic ­field measurement at low power consumption. The power requirement is a regulated 5V DC supply while the measured x-, y- and z-axes magnetic ­field components are available as 0-5V analogue outputs or optionally on a digital serial interface.
