MPO-MAG is designed as follows: Two identical magnetometers are used each with
their own dedicated electronics. This two sensors technique will be applied in order to
help determine the magnetic influence of the spacecraft.
The instrument hardware comprises an electronics box, two sensor units with their associated
thermal hardware and mechanical fixings, plus an electrical harness which connects the
sensors to the electronics box. The sensors are mounted on a deployable boom, whilst the
electronics box is located inside the spacecraft structure. The boom is a critical
subsystem both for the MPO-MAG instrument and the spacecraft. It enables both sensors
to be slightly removed from the spacecraft; combining the signal from both the inboard
and outboard sensors will help determine the magnetic interference from the spacecraft
itself. The MPO-MAG instrument is largely autonomous in operation, requiring a minimum
of commanding only for selecting from a set of science operations modes and corresponding
telemetry bit-rates. The two sensors measure the magnetic field with a sample rate of
128 Hz. These data will be reduced onboard to a lower temporal resolution depending on
the instrument mode: 64, 32, 16, 8, 4, 2, 1, and 0.5 Hz.To achieve the prime goals,
the separation of the measured magnetic field into its internal and external contributions
is required. Almost complete coverage of the surface is required and also as many
measurements above any given surface area as possible, which are needed to stabilize
the inversion procedure and remove intervals that contain transient field structures
due to magnetospheric processes.
