Dears,
any one can advice on the above question? is there any application can store these information?
I am doing some research and I am looking to get some information like DOP, number of satellite in view, GPS Quality indicator, etc
Thanks
iPhone 5s, iOS 9.3.1
iPhone GPS Support
The iPhone 3G and all subsequently released iPhone models use A-GPS -- or "Assisted GPS" -- which in basic terms accesses an intermediary server when it is not possible to connect directly via satellite -- indoors, for example -- and this server provides the nearest satellite with additional information to make it possible to more accurately determine a users position.
Apple explains that the iPhone 3G and all later models also use "wi-fi hotspots and cellular towers to get the most accurate location fast" when GPS is not the most convenient method of location detection. The iPhone 3GS and later iPhone models additionally have an integrated digital compass to also provide the direction one is facing, which is quite useful when combined with mapping software.
Likewise, with the exception of the original iPhone, iPhone models can provide real-time navigation assistance, too.
Thank you and I think it is clear but I am asking about the output e.g can I get HDOP information?
does iphone support GLONASS or only GPS?
thanks
All iPhones and all wifi+cellular iPads support GPS and GLONASS. To get any data from the location services system, you need an app, so search the App Store for GPS apps and see if one can show the data you want. The GPS chipset itself it only directly accessible by iOS's own location services sub-system. Third party apps request data from location services - they don't get it directly from the aGPS chipset.
Maybe something like MotionX GPS or GPS and Map Toolbox can show the data you wish to see.
What are the output of the GPS unit of the iphone 5s and 6s?
