Problems solved by technology

However, some mainstream orbit simulation software is expensive, and they are not even sold to China, and China's own simulation software develops slowly
In addition, the satellite parameters and deep space environment parameters in software simulation depend on artificial settings, which have great limitations in the simulation of actual conditions

Embodiment Construction

[0039] The technical solutions of the present invention will be described in detail below with reference to the accompanying drawings.

[0040] A satellite constellation orbit physics simulation experiment platform, such as figure 1 shown. The platform includes a first simulated satellite, a second simulated satellite, a first support device for making the first simulated satellite run according to the set orbit, a second support device for the second simulated satellite to run according to the set orbit, a controller and a display. The first support device includes a telescopic rod, a telescopic motor and a rotating motor. The first analog satellite is connected to one end of the telescopic rod. The output shaft of the telescopic motor and the rotating motor is connected to the telescopic rod. The controller sends a control command to the rotating motor to rotate. The motor drives the telescopic rod to rotate around the simulated earth center according to the control command...

Abstract

The invention discloses a satellite constellation orbit physics simulation experiment platform. Two simulation satellites are supported by a telescopic rod and a suspension arm capable of moving triaxially respectively, and the process of satellites orbiting around an orbit in space is simulated by controlling the rotation of the telescopic rod and triaxial movement of the suspension arm. The satellite constellation orbit physics simulation experiment platform can achieve the direct demonstration of satellite constellation orbiting effect, fill in a gap of physical simulation of the satelliteconstellation orbit in China, and break through the limitation that current satellite orbit simulation only stays in numerical calculation and software simulation.

Description

technical field [0001] The invention belongs to the technical field of satellite navigation, and particularly relates to a satellite orbit simulation experiment platform. Background technique [0002] Today's society is an information society, and artificial satellites are extremely important space information infrastructure and an important means for people to obtain information in an accurate and real-time manner. Various applications of satellites have become a powerful driving force for the development of the information society. However, from design to launch to orbital maintenance of artificial satellites, it is a high-investment, high-risk, long-cycle activity. Simulation technology can significantly reduce research costs due to its controllable, repeatable, economical and efficient nature. [0003] Due to the particularity of orbit research, the cost and conditions of physical simulation are relatively high. At present, the simulation of satellite orbits in the world...
