Actually the only reference I could find to the claim of a 500m cep was not from deghan but from the rather notorious anthony cordesman whose shall we say inaccuracies regarding irans missile forces are a matter of public record,I personally would take anything from him and indeed from most of the western right wing think tank "experts" with a very large helping of sodium chloride,but if you do have an actual link to deghan stating this himself then please by all means post it as I would certainly like to see it.Emad is 500 Meters and that's straight from Iran's own Defense minister at the time (Dehghan)!
The pershing 2 did indeed use radar based tercom as its target acquisition method and yes back in the mid 70s to get those radar maps you needed aircraft or sats,however that is certainly not the case today as it is possible to use high quality topographical maps instead,indeed without this very same capability irans new soumar and ya ali cruise missiles would probably have to depend either on gps/glonass or purely on inertial guidance.The most accurate version of the Pershing-2 used terrain counter mapping using an active radar & to do that you need space based sats to draw info from or Aircrafts that have previously mapped the area to give you info so how many Sat's did the U.S. have up in mid 70's & 80's vs how many we have up today???
Also, just because it has a proclaimed accuracy of 100 ft doesn't make it true! Your talking about a missile that's traveling at almost "3000 meters per second" so the processing power required to hit something with an accuracy of 30 meters at that speed was not there even for the U.S. in the 80's & I don't care what they claim fact is it's nothing but fiction! You talking about a ballistic missile built a decade before the Tomahawk with a CEP more accurate than the Tomahawk moving at speeds 10X faster than the Tomahawk I call that FICTION! and Propaganda!
As for the pershing 2 accuracy I see no real reason to doubt it,the americans extensively tested it before putting it into service and its not like it was having to hit a moving target either,you can see a clip of how it actually works here:

in addition the cruise missile,both alcm and tomahawk,were also from that very same time period as the pershing 2 ie the early to mid 70s,at around this time the americans were becoming more interested in the possibility of so called decapitation strikes which would have required much better accuracy than the previous systems possessed but fortunately several new technologies and improved guidance systems became available at around the same time to make this possible.The soviets certainly took this possibility very seriously and viewed both the pershing 2 and the cruise missile with alarm.Another us weapon from the same time period which also demonstrated extreme accuracy for the time was the mx missile/peacekeeper icbm which had a cep of between 90-120m[!!] by comparison the soviet icbm force had a cep of between 400-800m+.
We dont actually know exactly how the rq-170 or the other drones were captured,the gps spoofing was just one of the most popular theories and had been tested against simple drones in the us and found to be possible.1st It doesn't much matter if it's passive or NOT & Iran proved it when they hacked the RQ-170! 2ndly Right now Google maps can detect and give you real time traffic patterns using GPS installed on your cellphone and they can do it because GPS systems that are readily available are anything BUT passive to the people operating the sats! So yes it's passive but only to the people that aren't operating those sat's and are only secure if their ID information or location haven't been compromised
Gps receivers are passive but cell phones are not they are active emitters even when you are not actually using them to talk to someone and would be a potential security risk regardless of any gps component.
