Space Qualified Attitude Control Magnetometers

MEDA is a leading supplier of space qualified three-axis fluxgate magnetometers for spacecraft attitude determination and control applications. Our magnetometers have a long history of success in space dating back to the 1970s. The TAM-1 and TAM-2 series of space qualified fluxgate magnetometers offer the satellite attitude control system designer a lot of flexibility.
  • Field ranges from ±100 to ±1000 mG.
  • ±2.5, ±5.0, ±10.0 or 0 to 5 output voltage ranges.
  • Operate from a standard 28 volt power buss.
  • A calibration coil around each axis.
  • Wide operating temperature range.
The two fluxgate magnetometers differ in their physical configuration. The TAM-1 has a fluxgate sensor unit that is separate from the electronics unit. The sensor can be located outside the satellite platform on a boom where it is less influenced by magnetic sources within the spacecraft. The sensor can operate over the much wider temperature range (-90șC to +80șC) required of instruments in this severe environment. The TAM-2 integrates the fluxgate sensor and the electronics into one package. It is a compact low power magnetometer that is suitable for use where an external sensor is not needed. The standard acceptance tests include:
  • Dimensional and visual inspection.
  • Performance test at the operating temperatures.
  • Random vibration to the customer's specified levels.
  • Thermal cycle and burn-in to the customer's specification.
  • Final inspection.
The customer can specify additional tests if the environmental requirements are more severe than the current magnetometer qualification levels. Each delivered satellite magnetometer is accompanied by an End-Item-Data Package that includes its manufacturing history, acceptance test results, all required certifications and as-built documentation.
