Name
GOES 8 Magnetometer 1-Minute Data
Description

The NOAA Geostationary Operational Environment Satellite (GOES) key parameters. This data is a subset of the data available from the GOES Space Environment Monitor (SEM) instruments. It contains vector magnetic field in three coordinate systems: (1) Spacecraft P,E,N (2) GSM x,y,z and (3) GSE x,y,z. Spacecraft magnetic field is defined as: P - perpendicular to the spacecraft orbital plane or parallel to the Earth's spin axis in the case of a zero degree inclination orbit; E - perpendicular to P and directed earhtwards; and N - perpendicular to both P and E and directed eastwards.

SPASE version 2.0.0

Instrument: GOES 8, Triaxial Fluxgate Magnetometer

Instrument ID
spase://SMWG/Instrument/GOES8/MAG Get XML
Name
GOES 8, Triaxial Fluxgate Magnetometer
Description

The magnitude and direction of the magnetic field are measured by two redundant Schonstedt triaxial magnetometers located on a boom 3 m, and 2.7 m away from the spacecraft body. The electronics are located inside the body. The X, Y, Z component signals from the three axes are digitized by a 16-bit converter, at a sampling rate of 0.512 s. The sensitivity is 0.1 nT, and the range +/- 1000 nT. After temperature correction, and before (undescribed) stray-field correction, the accuracy is at about 1 nT level.

Description

GOES 8 is the 11th in a series of NASA-developed, NOAA-operated, geosynchronous and operational spacecraft. The triaxis-stabilized spacecraft carries (1) Imager and Sounder system to provide visible and infrared images of cloud cover, and to determine atmospheric temperature and water vapor content at various levels, (2) a meteorological data collection system to relay processed data from central weather facilities to regional stations equipped with APT and to collect and retransmit data from remotely located earth-based platforms, (3) a space environment monitor (SEM) system to measure proton, electron, and solar X-ray fluxes and magnetic fields, (4) a Search and Rescue (SAR) system to detect and relay distress calls from land and ocean, and (5) a WEFAX system to disseminate weather information to the user community via FAX. The cylindrically shaped spacecraft measures 190.5 cm in diameter and 230 cm in length, exclusive of a magnetometer that extends an additional 300 cm beyond the cylindrical shell. The imaging telescope is mounted on the equipment shelf and views the earth through a special aperture in the side of the spacecraft. The solar array of 1,057 W supplies two nickel-cadmium batteries of 12 Ampere-hour each. The CCSDS-compliant telemetry is in real-time at 2.0 kbs through S-bands. The eventual parking longitude of the spacecraft will be over 75 deg W. The SEC package (X-rays, H+, e-, monitors, and the Magnetometer) became inoperational on or before April 2003.
