To achieve drag-free control, Taiji satellites must be equipped with micro-thrusters that satisfy stringent requirements, including a continuously adjustable thrust, thrust resolution of 0.1 µN, thrust noise of
This album covers the interferometer system, gravity reference sensor, micro-thruster system, drag-free control, ultra-stable and ultra-static satellite technology, and introduces the data
Thus, a demand for a high-precision and continuously adjustable micronewton-level thrust has been proposed on the spacecraft micro-propulsion system.
Taking the specific micro-force perturbation and temperature fluctuation in the Taiji-1 interferometer as an example, we set up and experimentally verified the corresponding transfer function to quantify the
The Taiji Laboratory for Gravitational Wave Universe has developed a micro-thrust measurement system specifically for ground thrust measurement of a micro Hall thruster.
Preliminary in-orbit verification of Taiji-1 has showed HMTAs'' great potential in future, and the data in the experiments are presented in this paper.
As a simplified analysis, we pay attention to the specific perturbation situation where the micro-force perturbation noise or temperature fluctuations are subjected to only one of the contact surfaces in the
In the context of practical application, the specific mission configuration, orbit distribution, measurement technology, and payload of the project are summarized.
This paper presents the progress of a variable cold gas micro-thruster being developed for the Taiji program.
In the context of practical application, the specific mission configuration, orbit distribution, measurement technology, and payload of the project are
To satisfy the ultra-low microgravity requirements for ground testing of the Gravitational Reference Sensor (GRS)—the core payload of the “Taiji-1” mission—a newly designed experimental
