iPhone 5 and Satellite GPS

Also, if you really want to verify the presence of a real GPS receiver, I found an App called GPS2IP that can export the NMEA data, including how many sattelites are fixed. It costs money and can only export the data to other devices like your computer, for some reason Apple does not want you to be able to access this data on the device. It is not quick and simple, and requires some technical knowlegde, but can absolutley verify the real GPS receiver if used away from WiFi and Cell service. Seems a bit extreme, but it is one way to verify it if you question the published specs.

Can you or anyone here give advice on how to use just GPS input on a Sprint iPhone 4s? I want to turn the CDMA and GSM radios off so the battery isn't draining while searching for signal, and just use the GPS receiver in the phone. I can see how if I had a GSM iPhone I could get that done with the steps listed, but how do I get this done with a Sprint phone?

ok so the other day i downloaded an app for training its called "nike running" and after i used the app it will show me the place where i ran or the street.I dont have cellular data on my iphone so how is this happening ?

it will be cool that i can use my phone as a gps some time

I'm from Nicaragua so i dont know if this feature could be use worldwide

regardsss !!

Okay, I have an iPhone 4S and if you turn off cellular data and wifi, it can find your location and track it. I use myTracks for hiking and stuff. If only there was a way to turn on the GPS alone... I know you can put airplane mode on and then turn on wifi and Bluetooth but I'm not sure about a GPS. Too bad Apple didn't include a GPS widget in the new Control Center...

Hello speaking on this topic to ask a question:
There is an app for Iphone 5s to see the FIX satellites?
I'm interested to see how many satellites hooked my iphone at a precise moment.
For years, I'm looking for
thanks

Nope, for some reason no one seems to know Apple prevents access to that information, they feel that users should not know what satellites they are connected to. Since access to that info is standard on all GPS chips Apple has to actually have taken extra steps to hide the info.

It's the one thing that is keeping me from switching to iPhone even though I have an iPad and a Macbook.

Really?

That's why it's not accessible?

They didn't do it to make a simpler I/O for developers to get all location data, not only GPS?

There are apps that will do that. UltiMate GPS and Motion-X GPS will show info about the satellites. There are likely others too that I'm not aware of. But the app developer has to specifically build the ability to get and see that kind of data into their app - most nav. apps do not bother doing that as it is not part of their design function to display it.

The information is provided again by location services, which any app developer can use to access location based information. No app can directly interact with the hardware though - they must go through iOS to get data about or from hardware. That is part and parcel of iOS's whole security model to limit the very potential ofr apps to do unexpected or outright nasty things. They can ask for information from iOS but cannot directly access the underlying data itself (just as apps can share contacts info from iOS contacts, but they cannot directly read/write to the contacts database).

Nope. I have Motion X on the iPad Mini. It gives you a vague, endefined signal strength, not any actual sattelite data. Apple really does block access to almost all of the NMEA data, even to developers.

Location services does not give NMEA data, even to developers. No app on Apple can tell you which sattelites you are tracking like a regular GPS does. The data is there ont he chip, but Apple blcoks access to it for whatever reason.

Certainly very few users would have any use at all for that data. To most people "GPS" means the mapping and navigation software that uses position data fromt he actual GPS, not the actual GPS itself.

I'd love to ba able to access that data and be able to output it to other devices for projects, but on Apple stuff you can't. That's pretty much the onlyreason I still have an android phone when I have Apple tablets and a notebook.

Hi guys!

Several weeks ago I noticed issues with my iPhone 5 (iOS 7.0.4) using tracking app (like Runtastic, Strava, etc). It was a really poor situation to get a route. After all I had problems using car driving navigation app (like Yandex. Navigator). It was working definatly incorrect. It can't go by route (like it was early) to the point which I set - just a pulsing point moved through a map.

I have got the GPS Info app from the App Store. To test a GPS I turned wi-fi and cellular off . And... BOOM! The sad thing is the horizontal precision of the real GPS working. It was 1414 m. The app said the accuracy is POOR. OK, I reseted privacy settings and settings of connection (Settings > General > Reset). It is better now: the horizontal precision is 65 m ("the accuracy is good" shown). BUT my iPad 3 have only 5 m at the same settings and at the same place! iPad's accuracy is IDEAL here now!

What is the problem with my phone? How could I fix it? Maybe smb have time to get an app and test his iPhone 5 with GPS Info app? What is your result?

Thx in advance!

Hi there,

I joined this thread as a land owner wanting to make specific datapoints of fencelines, water points, water lines, roads etc. So, location accuracy within a few meters is important. I tried going a simple route, i.e. GaiaGPS which i know is a hiking app. I found the app crashed and location accuracy was a bit fuzzy. This led me to want to get a garmin, or perhaps an external GPS receiver. I guess my question is, does anyone have experience using these GPS add-on devices? It seems Bad Elf and DUAL both make them, and they seem to add WAAS capability.

I'm not trying to promote, just understand, thank you in advance!

I used the GPS on my old iP3G for similar use and it worked quite well with the GPSRecorder and GPS Ally apps. I compared lat/long to an old handheld Garmin unit... they weren't identical but seemed to be within a few meters of each other.

Huh?

Iphones have had GPS, which is satellite based, since the iphone 3g.

The GPS on my old iPhone 3G with no SIM card in it (and therefore no cell data) tracks me just fine when I'm out walking around (i.e., no wifi signal either).

There are apps that might suit your requirements. They include off-line maps. I do not have any of them but one I have looked at in the iTunes store is GPS Kit.
