AdGR AnDroid GPS receiver is an app designed to provide radio operators working with FH communications an accurate Zulu time hack. I39;ve tested this app for weeks and weeks now, almost every day, against a DAGR Trademarknamewhatever is C Rockwell collins and so far I haven39;t had any inconsistencies. That is, however, no guarantee that a device different from the ones I tested this app on will never return an incorrect time. Ensure that you test your phone before using this application for anything important. GPS needs to be turned on for this to work, as the time is retrieved from the actual GPS hardware in your device. If you have any requests or comments, feel free to email or comment, I39;m here to help
