I'm waiting for the day that we have a live online satellite feed so you can check the state of traffic on various roads before you set out. But I won't hold my breath for it anytime soon. B2003 |

Or ever -- geostationary satellites are much too high to focus on individual roads. Low orbit satellites don't spend long over any particular point on earth, and mostly pass over uninhabited areas with no roads. The only likely way for this to happen would be using either tethered balloons or drones. |

Not by vehicles reporting their position to satellites [1], or live photos from on high, but vehicles knowing where they are and sending periodic reports by some form of terrestrial mobile data. The Japanese have had a trail of weather forecasting by getting cars to report whether or not their windscreen wipers have been turned on. [1] There are still journalists who think GPS works by transmitting data from the ground to the satellite (and even one on BBC yesterday who think it's called GPRS!) -- Roland Perry |
