Does the Iphone 4 GPS work in airplane mode?
this didn't need a new topic
for a fatty you're a serious intellectual lightweight.
Obviously not. GPS needs line of sight and airplane mode turns off ALL transmitting devices on the phone...
No, i'm asking because my HTC desire's GPS does give me a location in airplane mode..Camm wrote:

If I turn airplane mode on but leave wifi on then the GPS works, but if wifi is off it doesn't work (on my iPhone 4s).
the fuck is airplane mode
another stupid buzzword?

pretty sure every phone has it, its where it turns the cell antenna off
GPS recievers don't transmit anything...CapnNismo wrote:

It's been around since the dawn of the smartphone/pda, if not for longer...Finray wrote:

Your thoughts, insights, and musings on this matter intrigue me
Much longer.
cut him some slack
By dawn of the smartphone/pda I'm referring to early 90s, not when iPhone came along and acted as if it was the first to do anything...FFLink wrote:

Just to clarify...

Sure about that? The assisted systems that most cell phones have are certainly not only receivers.FloppY_ wrote:

Hmm, I think some phones use the cell-towers to estimate their position aswell, that would be an issue... but GPS recievers like navigation units in your car should only recieve signals from 4 or more sattelites and estimate their location based on the that...CapnNismo wrote:

This is how it works on my iphone 4 too.Dauntless wrote:

It's probably the same chip controlling them both.
Yes, that's true. The iPhone, however, has assisted GPS, meaning it isn't as accurate or true as the GPS in a car unit. It uses the cell towers.FloppY_ wrote:

Assisted GPS just helps the GPS get a position using the cell tower, it's not any less of a gps than any other handheld gps. It's an added feature.CapnNismo wrote:

GPS in some cars can manage better when it loses the GPS position because it knows how fast the wheels are turning.
At first I was like "WTF", then I realized that some cars have built-in satnav... That's more rare than supercars here, pretty much everyone uses windshield mounted Garmin / TomTomsDauntless wrote:

Dauntless, a lot of window mounted GPS units have the same time except instead of being directly mounted to the car's diagnostics systems, they simply use an accelerometer. This is helpful, for instance, when you go through a tunnel. The GPS can still track your position and tell you about where you are and how much farther you have (and if you need to take the right or the left in the tunnel should you be in one of those kinds).
yeah, i was just saying that assisted GPS doesn't mean it's not as accurate
