AI Technical Summary
In multi-satellite network collaborative operation, the existing pulsed orbit control technology has low efficiency, resulting in inaccurate phase adjustment between networked satellites, increased fuel consumption, and affecting the orbit control accuracy of networked satellites.
By launching a ground-based injection command, the heating circuit of the catalyst bed in the single-component thruster is activated to preheat the catalyst bed to the set temperature. The opening and closing of the solenoid valves are controlled by the satellite control computer. Combined with the pre-jet pulse width sequence, the thrust output of the orbit control thruster is optimized to ensure that the catalyst and propellant are fully mixed and to improve orbit control accuracy.
It improves orbit control efficiency in multi-satellite network collaborative operation, enables precise phase adjustment between networked satellites, reduces fuel consumption, and improves the accuracy and stability of orbit control.
