Alternative PNT Augmentations for Handhelds

Yotta Navigation proposes to develop the MOUTman, a rugged, handheld, secure, high-precision real-time navigation system suitable for military operations. This system will take advantage of Yotta's existing expertise in several areas: inertial and differential GPS-assisted navigation, user interface design, efficient integration of components from mainstream suppliers, and our deep knowledge of real-time systems. The primary tracking device will maximize the use of recent advances in commercial-off-the-shelf (COTS) Micro-Electro-Mechanical Systems (MEMS) technologies. It will be extensible and allow for future anticipated GPS Modernization improvements, especially the evolution of military P(Y) capable devices to support M-Code. Components of the test system will closely match the existing GPS infrastructure already in place to support the warfighter, with a natural transition path from the legacy PLGR and DAGR units. Yotta's modular, extensible approach will bring consistently reliable sub-meter dynamic positioning and attitude, high-data rate throughput in excess of ten (10) hertz, and the ability to track horizontal and vertical position even in the total absence of GPS. Because the proposed SBIR solution can be built around an existing Yotta solution platform and architecture, a field-testable prototype system is achievable by the end of the Phase I. This Phase I effort will culminate in a high-quality proof-of-concept design, testable prototype, and quantifiable performance results. The approach will also permit significant time for testing, optimizations and enhancements during Phase II.
