Data Set Overview
=================
The main objective of the Giotto Magnetometer
Experiment is the investigation of the interaction
between Comet Halley and the solar wind at a distance
of 0.9 AU from the Sun, to within 500 km of the
cometary nucleus. A second objective is the study of
the interplanetary magnetic field. The
instrumentation consists of a triaxial and a separate
biaxial system of fluxgate sensors of the ring-core
type, the associated analogue electronics and a
digital pro- cessor. The measuring ranges of +/- 16
nT, +/- 64 nT, etc., up to +/- 65536 nT are digitis-
ed by a 12-bit analogue-to-digital converter,
allowing a sampling rate of 28.24 vectors per second
at encounter. Memory modes allow the bridging of
gaps in telemetry coverage of up to ten days. The
total mass of the instrument is 1360 g and its power
consumption 820 mW.

The main objective of the Giotto Magnetometer Experiment is the
investigation of the interaction between Comet Halley and the
solar wind at a distance of 0.9 AU from the Sun, to within 500 km
of the cometary nucleus. A second objective is the study of the
interplanetary magnetic field. The instrumentation consists of a
triaxial and a separate biaxial system of fluxgate sensors of the
ring-core type, the associated analogue electronics and a digital
processor. The measuring ranges of +/- 16 nT, +/- 64 nT, etc., up
to +/- 65536 nT are digitis- ed by a 12-bit analogue-to-digital
converter, allowing a sampling rate of 28.24 vectors per second
at encounter. Memory modes allow the bridging of gaps in
telemetry coverage of up to ten days. The total mass of the
instrument is 1360 g and its power consumption 820 mW.
