We require modification of a current iOS application. It is a GPS based app which uploads the GPS location using Standard Location Background Services. We require that this part of the app be modified to use Significant Change Services to start a background task to keep itself awake. While that background task is active, activate the standard location services API and get a high accuracy location. Upload a GPS location every 3 minutes within 10 minutes and close the background app until it is reactivated again with Significant Change Services.
We do have all original source code.
