Summary
The ORSTED satellite, also known as Orsted, is a Danish science satellite launched on February 23, 1999, from AFWTR SLC2W using the Delta 7920-10 launch vehicle. It measures 0.8 meters in length and has a diameter of 0.5 meters with a span of 8 meters, featuring a box plus antenna shape. The satellite weighs 62 kilograms at launch and is gravity gradient stabilized without any motor system. Its equipment includes a vector magnetometer, scalar magnetometer, star tracker, GPS receiver, and particle detector. ORSTED's power source consists of solar cells and batteries, and it was manufactured by TERMAB for DMI. The satellite’s primary purpose is scientific research in Earth’s magnetic field.
