SBIR-STTR Award

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.

Under this Phase II effort, NAVSYS will develop a handheld app and networking technologies for information exchange with sensors in a tactical environment. Developed on an Android device and deployed for CONOPS like those supporting TIGR, the application will provide real-time RF propagation (communications) performance parameters in urban, rural, and littoral environments for fixed and mobile assets. In Phase II we will use the app to demonstrate situational awareness of GPS threats and Signals of Opportunity (SoOP) to provide assured PNT to remote assets in areas around the user’s location. The use of handheld devices implies the need to research and design optimal network approaches to ensure it is appropriate for use in the tactical environment. NAVSYS will implement a network architecture based on commercial Internet of Things (IoT) technology to implement an RF Internet of Things (RIoT) sensor network to demonstrate automated resource and data discovery and cross-network, multi-domain, publishing and subscribing. A prototype RIoT network will be implemented, and a demonstration will be performed at the PNTAX live GPS jamming event of the GPS threat situational awareness capability and the ability to provide SoOP data to support Assured PNT in a GPS denied environment.
