GOES 9 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 9, Triaxial Fluxgate Magnetometer

Instrument ID
spase://SMWG/Instrument/GOES9/MAG Get XML
Name
GOES 9, 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.

GOES-NEXT
GOES-J
Description

The Geostationary Operational Environmental Satellite (GOES-J) is the second satellite in a series of next generation geosynchronous spacecraft, referred to as GOES-NEXT and represented by the GOES I through GOES M spacecraft. The GOES-NEXT series is a joint effort on the part of NASA and NOAA to provide continued operational monitoring of weather systems primarily over the United States, distribute meteorological data to regional and national weather offices within the USA, contribute to the development of an environmental data collection network, contribute to the search and rescue program, improve the capability for forcasting and provide real-time warnings of solar distrubances, and to extend knowledge and understanding of atmospheric processes to improve short and long-term weather forecasts. The GOES-NEXT series, extends the capabilities of the previous GOES 1-7 spacecraft. The GOES I-M spacecraft will be placed over the equator at 135 deg West or 75 deg West. The spacecraft structure is based on the Space Transportation System (STS)-launched, three-axis stabilized Insat (geostationary satellite for India) meteorological satellite design. The design allows unobstructed views of the Earth for operational coverage by the spacecraft sensors. The spacecraft configuration is a compact box-shaped main body that carries the Earth-observing instruments, a continuous-drive solar array attached to the south panel through a yoke assembly, and a solar pointing instrument gimbal mounted on the solar panel yoke. The main body accomodates the sensors, electronics, and support subsystems. The communication antennas, except the Tracking, Telemetry, and Command (TT&C) antenna, are hard-mounted to the Earth-facing panel. The Propulsion Module consists of the fuel and oxidizer tanks for the bipropellant propulsion subsystem mounted on the central cylinder. The Attitude and Orbit Control Substem (AOCS) provides attitude control of the spacecraft. The AOCS consists of the sensors, electronics, and the actuators. The GOES power is generated from the solar array and two 12 A-hr batteries. Power is automatically regulated during solar eclipses. The Image Navigation/Registration (INR) system provides Imager and Sounder data products in real-time to users. The Communications, Command, and Data Handling subsystem is comprised of antennas, receivers, transponders, transmitters, data encoders and encryptors and multiplexers. The Tracking Telemetry and Command (TT&C) subsystem provides the necessary monitor and command link between the spacecraft and the ground stations. The GOES-NEXT instruments consist of the following: (1) Earth Imaging System, a 5-channel visible and infrared radiometer which provides Earth imagery 24 hours a day; (2) Sounding System, a 19-channel discrete-filter radiometer for obtaining atmospheric temperature and moisture soundings; (3) a Space Environment Monitor (SEM), which consists of a magnetic field sensor, a solar X-ray sensor, an energetic particle sensor (EPS), and a High Energy Proton and Alpha Detector (HEPAD); (4) a Search and Rescue subsystem (SARSAT), which receives signals from 406 MHz distress beacons and relays them to the ground; (5) a Data Collection System (DCS) for collecting and relaying real-time information from Data Collection Platforms (DCPs) such as buoys, balloons, remote weather stations, ships, and aircraft; and (6) a Weather Facsimile (WEFAX) system which relays processed weather imagary from the Wallops Island station to the user community. The SEC package (X-rays, H+, e-, monitors, and the Magnetometer) became inoperational on or before April 2003.
