One word. ADS-B All of aviation is moving to it and is in the early implementation stages. Bring it to donres and have a 100% comprehensive tracking system. If course this will add to a drones price but I'm sure as with any other technology it will come down over time. (for those that don't know ADS-B is a live GPS feed transmitted to air traffic control)
Your point is interesting, but nothing is 100% by itself, especially in this case. First, anything reliant on GPS is fraught for potential short comings, many may not know or forget that it was the Clinton administration that removed the position locks/safeguards on the system. Thus allowing the boom in civilian use of it. However, those measures can easily be reinstated in relatively short order. If done, that makes the ADS-B virtually unusable and if that is the only system you are relying on for airspace deconfliction then you will have a serious problem in managing airspace.
Next, any kind of EMP can render the system useless, from an atmospheric nuke to a large solar flare. The results are the same regardless. Then other space obstacles can cause system problems too, such as space debris and meteors etc. There is also the possibility of sat failure (it has happened) which can lead to constellation degradation for a large region, and it cannot be easily fixed or remedied.
Lastly, opposing nation states can interfere with a GPS system at will through jamming, anti-sat measures, or other kinetic means. Also, the ability to achieve local jamming of the GPS signal has already been demonstrated and with relatively cheep equipment, which makes it useful to non nation states such as terrorists. Granted, if any of these were to occur we'd have bigger problems to be concerned with, but it does demonstrate that a GPS reliant system has many challenges that will not guarantee a 100% reliability.
Yes, we can debate the possibilities of whether any of these things might occur, keep in mind some already have, but the point is over dependence on technology for systems like airspace management can result in a fools folly, meaning you'll need something besides that system to ensure 100% capability and therefore reliability. |
