Anyone tested iPhone navigation in a gps blackout area (e.g. Near an air force base?). I used to live in Lompoc and GPS wouldn't work in most of the town owing to the proximity of Vandenberg AFB.
- omgtehlion 15y agoGLONASS uses nearly the same frequency range as GPS, so the answer is no.
- huhtenberg 15y agoTangentially related - IIRC GLONASS also happens to have an almost identical frame structure to GPS. Very peculiar fact given the context.
- georgecmu 15y agoI wasn't aware there of existence GPS blackout areas anywhere, esp. in the continental United States. Do you have more information that would support your statement? For what it's worth, GPS seems to work fine for a lot of people around Lompoc, CA: http://www.strava.com/rides-by-country/united-states/california/lompoc http://www.strava.com/rides-by-country/united-states/califor...
- Tloewald 15y agoThe evidence is personal experience. The blackout only affects a certain radius of Vandenberg which only covers a part of Lompoc.
- georgecmu 15y agoSo, what exactly happens there? Your device stops seeing satellites (loses lock)? Or does the reported uncertainty become on the order of hundreds of meters? Or does it simply give you confused directions when you're driving? Searching for combinations of terms like "GPS, blackout, airforce base, lompoc" only brings up this thread. I find it hard to believe that if it were a real occurrence no one else would notice and write/complain about it.
