This dataset is an add-on to the CHAMP Level 3 Magnetic/Electric Field (ME) data files of the `LEO' satellite 'CHAMP'. It contains the date, time and location of the CHAMP satellite when crossing the equator in ascending direction. The data has been derived from high precision GPS position measurements (RSO and PDO). Small gaps have been interpolated, larger gaps have been filled using orbit prediction from NASA Space Physics Data Facility (SPDF). The file format is CDF (NASA CDF) and contains all meta data for description, the content is an extended version of the SW_OPER_AUXAORBCNT product from Swarm satellite mission. Magnetic local time (MLT) at the equator crossing has been calculated using Emmert et. al (2010).
