Hmm... were going to start a new subject thread though as this ones gone quiet may as well continue to post here...
via Check_Thrust:
...I never said that terrorist groups can't or wouldn't use GNSS to their own means, it is quite a logical conclusion that they would try, just as groups have utilised mobile phone technology to detonate explosive devices, but are you suggesting that the world should shutdown every mobile phone network as well?...
Terrorists using GPS is unfortunately logical, and already happening.
Check_Thrust, your obviously new to the discussion because the mobile phone detonator argument has been bought up in pprune before re GPS guided terror drones. The phone bomb scenarios/events are typically a bomb is placed with a mobile phone detonator and then later detonated by another phone. This requires terrorists to be in country and a lot of recognisance and logistical effort to set up. Whilst these sort of attacks happen around the world here in Oz the chances of terrorists being captured pre attack or post attack are very high so repeatability of attack likely nil. A very high cost attack with the high probability of traceback to the terror group leaders makes even the contemplation of this form of attack low. Would we shut down the mobile phone network for a possible one-off attack? doubtful.
On the other hand, GPS guided terror weapons can be launched out side of Australian territory. At most, all thats needed to be done in country is vertical and lateral destination co-ordinates for the GPS. If needed a year or two before the attack a tourist takes some pictures or somebody just drives by.
A scenario i presented some years ago...
A GPS guided terrorist drone, or drones, just wanders in over the Oz coastline and proceeds to a target. Likely unseen until the target is hit. Where did it come from and who sent it ? Whens the next one coming and from where ?
The GPS guided bomb drone doesn't need to be large, a hand grenade sized bomb payload delivered to a few square metres of airspace would be very effective from a terrorists point of view. Repeatability of attack guaranteed with public concern being very high.
Nuff fer now...
