Abstract: In order to obtain the space flight experiment data to verify the space environmental adaptability，compatibility with the spacecraft，space working characteristic，and the difference of space flight performance and ground data of hall electric propulsion system，the flight test of LHT-100 hall electric propulsion system was conducted on SJ-17 satellite. The flight test results of the LHT-100 hall electric propulsion system are evaluated in detail. The results indicate that the each operation parameter satisfies the corresponding design requirements of the LHT-100 hall electric propulsion system in the entire flight test period，in which its thrust is 79.5mN，the specific impulse is 1531s，the power is below 1.527kW，the time of single longest ignition is 8 hour，the orbital system switch times are greater than 24，the cumulative ignition time is greater than 3028 minutes. The flight test data are comparatively consistent with the ground data.
