Beidang let the two dust in the universe talk privately
Beidou based on inter-satellite links can maintain autonomous operation through mutual calibration for a period of time. This is the ability of autonomous navigation that we will talk about in the future.
Satellite can also load APP
Everyone who does software knows that bugs can’t be repaired. In fact, this sentence also applies to our satellite development industry. In a limited time, it is difficult for us to pat our breasts and say that we have solved all the problems. After the satellite goes to the sky, there will be no more problems.
What is the function of a satellite when it is launched? What is it like? What if there is a problem with its orbit? Sorry, there is no way.
Now, we have implemented the function of On-Track Reconstruction on Beidou. This means that apart from the firmware, other CPUs, DSPs, and SPGAs can all be reconstructed on-track.
A satellite that keeps pace with the times
That is to say, When the satellite has exposed some new problems after going to heaven, we can let the system upgrade itself and constantly patch ourselves.
If our users put forward new requirements, there is no need to relaunch a satellite. Can realize new functions on the ground, test
