Why is GPS even a thing with this? A few infrared gates to start/stop the clock and a known distance = computing the speed.
Instead lets time signals traveling in space and back. Sheesh.
- sorenjan 6y agoBesides not having to reach the top speed at a certain location, it also allows them to break multiple records at once. Koenigsegg has a list of records from their run, like "Flying kilometer on a public road" and "0-400-0 km/h". https://www.koenigsegg.com/koenigsegg-agera-rs-achieves-multiple-production-car-world-speed-records/ https://www.koenigsegg.com/koenigsegg-agera-rs-achieves-mult...
- jcrawfordor 6y agoGPS can provide highly accurate measurements using existing infrastructure and relatively low cost hardware. It also makes the results highly auditable since the GPS (and assisted GPS) system is public and well-documented, and open, standards-compliant methods exist in the surveying and DAQ industry for working with GPS data. Laser gates certainly have advantages, but they require more setup and ultimately I am skeptical that they would provide more certainty than GPS results. As mentioned elsewhere a survey GPS receiver can produce raw data which can be processed after the fact as a form of audit, something not really possible with laser gates.
- jiofih 6y ago> I am skeptical that they would provide more certainty Why on earth? They will literally produce two time stamps + known physical distance. What can be uncertain about that? Why is it any less auditable (or possible to tamper) then a GPS log?
- jcrawfordor 6y agoTwo timestamps would be trivial to fabricate while a raw GPS log would be technically complex to fabricate. Not impossible, but you'd need people with special expertise and probably custom software.
