- valarauca1 12y agoNope still done with GPS [1]. There was talk in 2013 about dropping it for cost savings. [1] http://en.m.wikipedia.org/wiki/Global_Positioning_System http://en.m.wikipedia.org/wiki/Global_Positioning_System
- MrBuddyCasino 12y agoHeres the money quote: "GPS satellites carry a set of nuclear detonation detectors consisting of an optical sensor (Y-sensor), an X-ray sensor, a dosimeter, and an electromagnetic pulse (EMP) sensor (W-sensor), that form a major portion of the United States Nuclear Detonation Detection System.[76][77] General William Shelton has stated that this feature may be dropped from future satellites in order to save money.[78]
- arethuza 12y agoSome also carry bhangmeters - devices for detecting nuclear explosions named after a variety of cannabis! http://en.wikipedia.org/wiki/Bhangmeter http://en.wikipedia.org/wiki/Bhangmeter "the joke being that one would have to be on drugs to believe the bhangmeter detectors would work properly"
- MrBuddyCasino 12y agoCan't believe I've missed the only opportunity to mention bhangmeters - indeed a fun fact.
- hga 12y agoOriginally, since it started in 1963, long before GPS: https://en.wikipedia.org/wiki/Vela_(satellite) https://en.wikipedia.org/wiki/Vela_(satellite) Bundling that mission into GPS satellites was an obvious way to save costs and very possibley get better results.
