I am developing an application using the cordova and found a need to take the data of latitude and longitude of the User, but my application will be used offline (without internet access).
I'm with two questions:
1 - How to check if the unit is active GPS or not?
2 - How I can get the latitude and longitude Offline without internet connection? It's possible?
Best How To :
I´ll try to answer you:
1.- There you have the way to use PhoneGap GeoLication API to check location, and if GPS is enabled. Check this too: Use PhoneGap to Check if GPS is enabled
2.- Yes, the GPS is a satellite system that allows your device to track it´s current position on earth. It´s independent from your Cellphone operator, and then, from the Internet Connection. Then, your device will be able to know it´s position. HTML5 offline mode and geolocation
In addition, you´ll probably need Internet connection to show a map. There are not much solutions for offline maps. Just artisan ones: http://davidrs.com/wp/phonegap-3-0-leaflet-offline-maps/
Hope it helps
REMEMBER: When turning on plane mode, most of devices will turn off GPS antenna too.
