Handheld Apps for Warfighters

With the advent of Google"s open Android development environment, it is now possible to inexpensively and rapidly develop new applications (apps) for operation on Android mobile phones. All major cellular service providers now offer Android phone options to their customers and Google maintains an open marketplace where developers can post their applications for customer download. An Apps Marketplace can also be used for rapid distribution of applications to the warfighter. NAVSYS previously developed a JLOC (GPS Jammer Location) system that is currently being widely used by warfighters to provide early detection of GPS jamming on the battlefield and situational awareness on the effect of known GPS jammers. Under this SBIR effort, we shall design and implement a prototype JLOC Android application that performs these functions and integrate this with our JLOC Server. We shall test the ability of a mobile phone to provide JLOC sensor reports using its internal GPS and will solicit warfighter feedback on the utility of the application and develop a Phase II proposal based on this feedback. Under the Phase I Option, we shall provide upgrades to our existing JLOC Server to support an initial operational capability for smart phone users through this JLOC Android application.
