How does the Google high air balloon navigate?

via:CnBeta     time:2018/3/9 21:36:05     readed:346

Each balloon has a solar powered pump that moves up and down by releasing or adding gas. In the pump's help, the balloon can enter or leave the intermittent wind in the stratosphere. To create a navigation system, the Project Loon team to understand the movement of stratospheric wind. They first took advantage of the models and predictions published by the scientific institutions, and then launched balloons to obtain data from the target area.

It is impossible to launch the balloon all over the place, so the team continues to run the simulation to supplement the model. Since the first flight test was carried out in 2013, the team has been running simulation. All the simulations are used to debug the models and algorithms of the navigation system. Its navigation system is highly automated, and a balloon formation requires only one or two people to operate.

The system is not perfect, still in the experimental stage, so the Project Loon project is not currently sharing data.
