INTEGRAL

NSSDCA/COSPAR ID: 2002-048A

Description

The International Gamma-Ray Astrophysics Laboratory (INTEGRAL) is a European Space Agency (ESA) mission designed to study celestial gamma-ray sources in the 15 keV to 10 MeV energy range. The primary INTEGRAL science payload consists of a gamma ray spectrometer (SPI) operating over 20 keV-8 MeV, a gamma ray imager (IBIS) operating over 15 keV-10 MeV, an X-ray monitor (JEM-X) operating in the 3-35 keV band, and an Optical Monitoring Camera (OMC) operating at 550 nm.

The spacecraft was launched on October 17, 2002 into a 66 hr., 639 x 153,000 km orbit at 51.7 degrees inclination. The mission is scheduled to last 2 years, and up to 5 years is possible. The spacecraft is three-axis stabilized with an absolute pointing error of 5 (y,z) to 15 (x) arcmin and an absolute measurement error of 1 (y,z) to 3 (x) arcmin. The spacecraft with solar panels stowed is roughly 3 x 4 x 5 m in size with a mass of about 4000 kg, 520 kg of that being hydrazine fuel. Science telemetry will be transmitted in S-band at 86 kbit/s to ground stations in Redu (Belgium) and Goldstone (US).
