For years now, Vehicle Excise Duty (VED or road tax) has been based on emissions. The manufacturers have to have all their cars tested and the information is stored in a government database. It has been available for years on the VED website. Just download an XLS version and then sort on the emissions column - or any that takes your fancy:
Or, more correctly, the US military doesn't rely on those GPS signals that are available for civilian use.
Signals for at least two positioning systems are transmitted by each GPS satellite. There is a coarse signal which is used by our satnavs. The accuracy of this is limited and can be worsened at any moment if they switch Selective Availability (SA) back on. There is another signal that is more precise and is much more difficult to decode and, I imagine, is what they use to guide their missiles.
