Radar would probably work better, assuming that works through the atmosphere, and assuming it should act as a backup to ADS. That could work on ships as well, which also need to be tracked due to recent "accidental dragging of anchor" incidents.
- nradov 2y agoRadar has been used on satellites for ocean surveillance before but it takes a lot of power. That means carrying a nuclear reactor, or enormous solar panels plus batteries. And a huge constellation would be needed to achieve anything like continuous coverage. http://www.astronautix.com/u/us-a.html http://www.astronautix.com/u/us-a.html It probably wouldn't be feasible to have a single constellation tracking both aircraft and ships. Different types of radar operating on different frequencies would be needed for those applications.
