Abstract: The electromagnetic interference(EMI) of radiofrequency(RF) equipments between human spacecraft and adjoint satellite was investigated. Based on the design of RF equipments, the model of calculating safety margin was built and the equivalent interference between transmitting antenna and receiving antenna was analyzed. To guarantee the electromegnetic compatibility, the minimal safe distance of two spacecrafts was obtained. The results show that the approach proposed in the paper can forecast the electromagnetic interference between human spacecraft and adjoint satellite, and provide technical support for the fulfillment of the mission.

Key words: human spacecraft, adjoint satellite, RF compatibility, analytical model
