The THEMIS FGM benefits from long-term experience in the design of ring cores and sensors. Tests and calibration have been performed in high-precision facilities developed for a number of previous missions. The FGM uses an updated technology developed in Germany that directly digitized the sensors' signals and replaces the analog hardware by software. Use of the digital fluxgate technology results in lower mass and improved robustness. Technical University of Braunschweig, (TU-BS), Germany.

Stage 42: Dayside Science Phase, HSO Optimization with MMS and VAP. In the dayside science phase the apogee of P3, P4, and P5 are approximately 12 Re. The probes are separated by 1000 km to a few Earth radii at apogee. MMS is at opposition in the tail. THM-MMS on resonant orbits, to study dayside-nightside reconnection simultaneously. Stage 41: Dayside Science Phase, HSO Optimization with MMS and VAP. Stage 40: Dusk Science Phase, HSO Optimization with MMS and VAP. In the tail science phase the apogee of...

The THEMIS Electric Field Instrument (EFI) measures the electric fields in three directions. One pair of sensors is deployed to 20 meters, the other pair to 25 meters. Two stiff telescopic booms extend sensors perpendicular to the four spinning cables and along the probe's spin axis. Sensors - Space Sciences Laboratory, University of California, Berkeley. Data Processing - Laboratory for Atmospheric and Space Physics (LASP), University of Colorado, Boulder. Would you like to see:. Table of EFI Parameters.

On-board Spin FIT module. Given a spin rate of 3 seconds, the use of 128 Hz data for spin fitting puts an apparent phase shift of 360/(3*128) or roughly 0.9 degrees into the results. While this meets the 1.0 degree requirement, the phase shift correction can be determined on the ground using the spin pulse time data relative to the 1Hz tick which is the basis of the 128 Hz data. Detailed information on the FIT module and spin-fit processing is available in the Flight Software Documents [FIT Module].
