Electric propulsion technology which has the advantages of high specific impulse, small thrust becomes the preferred way of space exploration in future. To ensure the safety and effectiveness of electric propulsion technology applications, the assessment of its performance is needed. The GNSS technology is now used for orbit determination, time service and so on, and it can be used for onboard thrust estimation. The paper gives the thrust model first. Then it gives the method to estimate the thrust for low and circle satellite orbit and the workflow using GNSS precision orbit determination Technology. At last, the simulation is made to analyse the semi-major axis variation under the thrust in the velocity direction. The result of Grace real time orbit and precision orbit is also give to prove the validity of the method in paper. The paper puts forward a suggestion that the real time orbit determination technology can be used for onboard engine thrust rapid assessment.
