The magnetometer SG-R8
This magnetometer is designed for studying space and time
variations of the magnetic field intensity. In addition, it enables
one to determine the attitude of the subsatellite with respect to
the magnetic field vector.
SG-R8 is a triaxial flux-gate magnetometer with automatic switching
of sensitivity. Its characteristics are given in the Table.
| R a n g e , nT | Resolution, nT |
| +/- 65536 | 8 |
| +/- 8192 | 1 |
| +/- 1024 | 0.125 |
| +/- 128 | 15.6 pT |
The data from the magnetometer pass through a digital converter,
which has 13 bits and the sign. Its operation is synchronized with the
STS telemetry system.
The main output of the magnetometer is digital. For emergency
situations the device has one analog output, from which one can obtain
the Hx , Hy , and Hz data with lower accuracy (8 bits).
The detector of the magnetometer is fixed at the top of a rigid
short boom, which enables one to determine precisely the attitude oft
he magnetometer axes with respect to the construction axes of the
subsatellite.
