True. You can't argue about the lack of GPS trackers, though. Every shipping container has one nowadays.

- joezydeco 13y agoReading GPS is cheap and easy. Sending information back is not. Those shipping container trackers use GSM to call home. They're cell phones. What happens when that container is in the middle of the Pacific Ocean?
- fnordfnordfnord 13y agoThat's an interesting question. Mini "cell tower" on the ship with satellite link?
- KaiserPro 13y agoor you could just use radar, which only requires your own radar to work....
- joezydeco 13y agoThe original topic here was "why don't planes have GPS trackers on them and constantly report in, if trackers are so cheap and every car/truck/container/phone on the planet can have one?" How does a plane get data back to the ground when it's 7 miles up and 1000 miles from shore? You have to have a satellite or long-range VHF link.
