In support of the USNG Emergency Location Marker (ELM) system, USNGStore.com and USNGCenter.org offer a FREE browser-based application that uses the GPS chip of recent model smart phones and hand-held computers (models since approximately 2011) to generate a USNG position display. Because the program is browser based, it can be used with ANY operating system.*
Provided the URL has been saved in the mobile platform’s browser, the display will operate dynamically and does not require an Internet connection. The generated location display will closely mimic the appearance of an USNG ELM. And, as long as the mobile platform’s browser is left open, the location display will be continuously updated, just as would be the case with a GPS unit.
If you order this product, you will be able to download a document explaining how to use the USNG App. But you don't need to go through the ordering process to do this, simply open the USNG App Instructions or read more on the USNG Center's USNG App Page.
You can also link directly to the app using this URL: usngapp.org
* Note: Some older versions of iOS may have font resize issues when the device is switched between horizontal and vertical orientation.
Attention App Developers: We're looking for a volunteer to convert this web-based app to an iOS and/or Android app. Please contact us if you are interested.
