But Industry Canada, which regulates the country’s telecommunications, decided against it, saying the devices could infringe on personal freedom and affect public safety by crippling communication with law enforcement and security agencies.
Experts are starting to delve into how well the Global Positioning System (GPS) satellite navigation network resists the effects of electronic GPS jammer— intentional or accidental. The emerging answer is not very well.
The news of the spy plane’s GPS troubles comes on the heels of rumors that North Korea is working on a new (or souping up an old) jammer. South Korean officials have claimed that Kim’s jammers had a range of between 50-100 kilometers.
