    Abstract
  • China Seismo-Electromagnetic Satellite (CSES) is the first domestic satellite for electromagnetic science experiment in near Earth orbit. Space magnetic field detection is one of the primary scientific objectives of CSES, which is based on long-term steady vector magnetic measurement. Flux-gate magnetometer and Coupled Dark State magnetometer are employed to detect vector and scalar magnetic field respectively. Using fitting method, we could get absolute accuracy data of vector magnetic field. A method about flux-gate magnetometer vector data calibration is introduced using scalar magnetic field data, and it ensures the accuracy of vector magnetic field data. The performance of this method is evaluated by simulation, and it gives an accuracy of 1 nT.
