technical field [0001] The invention relates to a modular propulsion service system based on mixed mode propulsion, which belongs to the field of space control actuators. Background technique [0002] There are currently two typical solutions for satellite orbit transfer. One is that the satellite itself is equipped with a dual-component unified propulsion system. The satellite propulsion system is used for orbit transfer. A larger-scale propulsion system needs to be configured in the satellite, resulting in the satellite being in orbit. The weight is heavy, which affects the performance of the satellite; at the same time, because the propulsion system is completely integrated on the satellite platform, it brings great restrictions on the configuration and structural layout of the satellite; finally, the satellite propulsion system is usually a two-component unified propulsion system, which adopts a long-life design , to meet the mission requirements of the satellite in orbi...

Problems solved by technology

[0002] There are currently two typical solutions for satellite orbit transfer. One is that the satellite itself is equipped with a dual-component unified propulsion system. The satellite propulsion system is used for orbit transfer. A larger-scale propulsion system needs to be configured in the satellite, resulting in the satellite being in orbit. The weight is heavy, which affects the performance of the satellite; at the same time, because the propulsion system is completely integrated on the satellite platform, it brings great restrictions on the configuration and structural layout of the satellite; finally, the satellite propulsion system is usually a two-component unified propulsion system, which adopts a long-life design , to meet the mission requirements of the satellite in orbit for 15 years, so the price is expensive

[0003] The other is to use the upper stage to complete the orbit transfer of the satellite. Since the upper stage is an independent aircraft, it needs to be equipped with a complete electronic system, and its dry weight is relatively large, which affects the effective quality of the satellite into orbit.

At the same time, the upper-stage orbit-changing engine adopts a pump pressure propulsion system, and the attitude control adopts a squeeze-type propulsion system. The system is heavy and the cost is high.
