ESA Swarm Mission - Level 1b Products

The ESA Earth Explorer mission, Swarm, is scheduled for launch in July 2012. The objective of the Swarm mission is to provide the best ever survey of the geomagnetic field and its temporal evolution by means of three formation flying spacecrafts in near Earth, polar orbits between 300 and 530 km altitude. The Level 1b Products of the Swarm mission contain time-series of the quality screened, calibrated, corrected, and fully geo-localized measurements of the magnetic field intensity, the magnetic field vector (provided in both instrument and Earth-fixed frames), the plasma density, temperature, and velocity. Additionally, quality screened and pre-calibrated measurements of the non-gravitational accelerations are provided. Geo-localization is performed by 24-channel GPS receivers and by means of unique, three head Advanced Stellar Compasses for high-precision satellite attitude information. The Swarm Level 1b data will be provided in daily products separately for each of the three Swarm spacecrafts. This poster will present detailed lists of the contents of the Swarm Level 1b Products and brief descriptions of the processing algorithms used in the generation of these data.
