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.

The five spin-stabilized (spin period = 3 seconds) THEMIS probes carry the comprehensive packages of plasma and field instruments needed to determine the cause of geomagnetic substorms. The instruments being flown are:. Electric field instruments (EFI). Search coil magnetometers (SCM). Solid state telescopes (SST). All-sky white light imagers (ASI). Digital Fields Board (DFB)-Filter Bank (FBK)-Fourier Power Spectra (FFT). On-board Spin Fits (FIT) from EFI and FGM Instruments. Data Policy and Credits.

TDAS 9.0 (including SPEDAS framework version 1.00). THEMIS data can be accessed using TDAS: the THEMIS Data Analysis Software. The current release is TDAS 9.0. This release also includes version 1.00 of the SPEDAS framework, which is now required to run TDAS. SPEDAS stands for "Space Physics Environment Data Analysis Software". There is a blog. On the SPEDAS software. And can download data from dozens of NASA space missions. Read more about the relationship between TDAS and SPEDAS. For Linux, we also off...

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.

And an interactive map is available here. Thumbnail images are transmitted in almost real-time from the sites and corresponding overview plots and CDF-data-files are available about two days following data collection. The full-resolution 256x256 pixel images are transferred via hard-disk swap and become available approximately 3-5 months after data collection.

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].

ATK Space Systems manufactured the THEMIS spacecraft (probe bus). The five THEMIS probes are identical in design and are capable of being placed in any THEMIS orbit. This provided robustness to the constellation design and allowed for any one of the probes to be placed in any orbit.
