  product description
  

  The satellite remanence test system Snapshot-MMF is a device designed for the space sector for the measurement of the magnetic field of satellite payloads or spacecraft components, using multiple fixed magnetometers for high-precision measurements, the magnetic field generated by the equipment under test (EUT) , for magnetic cleaning applications. Snapshot-MMF was designed after an in-depth study of various possible multi-magnetometer arrangements, considering the optimal number of magnetometers and their relative positions, in order to achieve fast measurement times and maximum measurement repeatability. The facility eliminates the use of Helmholtz coils to cancel the Earth's magnetic field during measurements.

  
  

  Features

  • Radial and vertical adjustment of the magnetometer

  • EUT vertical adjustment

  • Software-guided sequential (step-by-step) measurement procedure

  • Software based measurements

  • Acquisition, data filtering and reporting

  • EUT magnetic signal total

  • Measurement time ~1 min (total time includes background field measurement)

  • Avoid the influence of environmental magnetic field changes

  
  

  Applications

    Snapshot-MMF has been used by the European Space Agency-European Space Research and Technology Centre (ESA/ESTEC) to perform accurate measurements of electronic EUT and magnetic dipole modeling, useful for applications such as spacecraft magnetic cleanliness. The main application of this facility is to obtain the "magnetic signature" of the EUT. The measurement area is called "magnetic cleanliness" and applies to spacecraft units (service modules or payloads); most space missions have stringent requirements for magnetic cleanliness. The facility can be used for DC and AC magnetic field measurements, AC measurements in the frequency range up to 50 kHz, and a test plan can be provided for DC measurements.

  
  

  Measurement plan

  Snapshot-MMF is a solution for magnetic cleanliness measurement. Using Snapshot-MMF, users can use a three-step process to measure the total DC magnetic field from the EUT of the device under test without the use of 3D Helmholtz coils;

  Step 1: Measure the environmental field (including the earth field); B (environment, before)

  Step 2: The test engineer places the EUT in the middle of the facility and measures the magnetic field which is now B (EUT+Ambient)

  Step 3: Measure the environmental field again (including the earth field); B (environment, after)

  Then the total EUT DC magnetic field is B(EUT+Ambient) – (B(ambient, after) + B (ambient, before))/2.

  Measurements should be taken as quickly as possible to reduce the effects of changes in Earth's magnetic field. Typically, for small EUTs, measurements can be completed within 30 seconds. Time may increase for larger EUTs with complex structures that require more time to be placed on the Snapshot-MMF turntable.

  The measurement data can be provided to the MDM solver to represent an EUT with multiple dipoles for further simulation (i.e. at the system level). The solver fits the measurement dataset to multiple dipoles representing the EUT's magnetic behavior.
