Problems solved by technology

STK can quickly and easily analyze various complex space missions, and provide realistic 3D visualization dynamic scenes; but it only provides certain secondary development capabilities with limited interfaces, and its independent scalability, reusability and system integration are poor , and do not have independent property rights, it takes a lot of scientific research funds to purchase

In China, many aerospace science and technology workers have also conducted in-depth research, but judging from the current research status of domestic spacecraft in-orbit simulation, most simulation systems are still limited to the calculation of simulated orbital attitude data, and the degree of visualization of simulation results not high
