Precise Orbit Determination of the China Seismo-Electromagnetic Satellite (CSES) Using Onboard GPS and BDS Observations
The Global Navigation Satellite System (GNSS) occultation receiver onboard the China Seismo-Electromagnetic Satellite (CSES) can provide dual-frequency observations for both GPS and BDS-2 satellites.In this study, the data quality and orbit determination performance of the CSES are assessed.Severe data loss of about 30% is observed in GPS P2/L2 dat
