GOES 12 magnetic field data at 0.512 second time resolution. The vector magnetic field is given in the spacecraft (s/c) earth-referenced coordinate system: Hp, He, Hn, and Ht, where Hp is perpendicular to the satellite orbital plane, or parallel to Earth's spin axis in the case of a zero degree inclination orbit; He is perpendicular to Hp and directed earthwards; Hn is perpendicular to both Hp and He and directed eastwards; and Ht is the total field. This data product also provides GOES 12 satellite positions and velocities derived from SSCWEB GEI ephemeris, interpolated to one minute time resolution. The magnetometer data are downlinked from the spacecraft in real-time to the NOAA Space Weather Prediction Center (SWPC) in Boulder, CO. The data from the raw Command and Data Acquisition (CDA) telemetry stream are processed by pre-processors at SWPC and from there 1-minute averages are distributed to SWPC Space Weather Operations, as well a archived at NOAA?s National Geophysical Data Center (NGDC) and NASA?s Coordinated Data Analysis Web (http://cdaweb.gsfc.nasa.gov/). The raw high-resolution data are corrected and processed at NOAA?s SWPC, and later archived at NGDC. The major issue for processing the high-resolution data is correction for the magnetic signature of spacecraft torquer currents as briefly discussed in the magnetometer instrument descriptions. In normal operation, the magnetometer samples its three axes every 0.512 seconds, synchronized with the telemetry frames. The magnetometer has an anti-aliasing low-pass filter on each axis. As part of the attitude control on the spacecraft, there are two magnetic torquers. At the magnetometers, these torquers can generate magnetic fields larger than the ambient fields to be measured. Therefore signals from these torquer currents need to be removed. The torquer currents are measured at the same rate as the magnetometer rate, and the currents are used to correct the magnetometer measurements. However, the torquer currents were not low-pass filtered. As a result, large instantaneous steps in the torquer currents show up in the magnetometer data as a delayed, slowly rising wave with some ringing, just what one would expect from the magnetometer low-pass filters. The so-called ?Farthing coefficients? simulate, from a short past history of the torquer measurements, the effects of the magnetometer filters. The torquer current changes are asynchronous with the telemetry frames and the timing between these events must be measured to a eighth of a telemetry frame interval for good performance. The transient responses in changes in torquer currents are reduced, but not eliminated for large changes in torquer currents. There exists one opportunity at the beginning of each mission to perform a spacecraft rotation maneuver to determine magnetometer offsets. These offsets are used through the duration of each satellite's lifetime. Approximate coefficients are: * 0.8 milliampere per torquer current count * 4 counts per torquer current command step (3.2 milliampere per command step) * 410 milliamperes full scale current * 32 magnetometer counts per nT (approximate) * 8 torquer step counts can be up to approximately 0.5 nT (depends on axis, which torquer, which satellite, etc.)

The magnetic field sensor, located at a few meters away from the spacecraft was designed to provide the orthogonal components of the magnetic field: Hp was parallel to the spin axis that was held nearly in the direction of Earth's axis, He was directed toward Earth center, and Hn pointed eastward. The magnetometer had a range of +/- 1000 nT (without saturation) and a resolution of 0.1 nT. Data files contain long descriptive header.
