Interball-Tail Magnetic field measurements
Magnetic field measurements on-board the Interball Tail Probe are carried out by the FM-3I and MIF instruments. FM-3I consists of two flux-gate magnetometers M1 and M2 covering two different ranges: 200 nT and 1000 nT. The M2 instrument is mostly used to perform the attitude control of the INTERBALL TAIL spacecraft. M1 magnetometer data are transmitted to the scientific SSNI telemetry system at rates 0.125-16 vectors/s depending on the instrument operating mode. The magnetic field data from the M2 magnetometer are transmitted at the rate 1 vectors per 6 sec. to the BNS attitude control system. MIF magnetometer has the next parameters: measured range 0.3-37.5 nT, frequency range 0-2 Hz, sampling rate from 1/4 to 8 measurements per second. FM-3 M2 magnetometer failed in February 1996, FM-3 M1 and MIF are working until now.
Data presented here are the combination of the data of all magnetometers. First of all FM-3 M1 data are used, if they are absent, MIF data used and if data of both magnetometer are absent, FM-3 M2 data presented. In case of FM-3 M1 and MIF, data are averaged for 6 seconds intervals.
Magnetic components in GSE system presented as separate ASCII files for each continuos intervals. Satellite position, in GSE and GSM with 20 min step calculated by IKI Situation Analysis Center also presented in ASCII file. Orbit plots and other orbital data available from IKI WEB server.
