Smart Adaptive GPS Equipment (SAGE)

Ground, vehicle and airborne-based GPS receivers are subject to a variety of natural and man-made interference. Environmental impairments such as reduced signal strength due to heavy foliage, multipath reflections due to obstacles such as tall buildings and mountains are more pronounced in ground-based systems. Airborne platforms are more susceptible to jamming from a variety of sources. Interference rejection electronics for GPS receivers have been developed and successfully deployed on vehicles, aircraft, and large munitions. However, military GPS solutions today are based on rigid architectures and stove-pipe product lines unique to each manufacturer that prevents user equipment interoperability and stifles innovation towards development of advanced receiver technology such as cognitive and adaptive reception. The program proposes to develop a Smart Adaptive GPS Equipment (SAGE) System based on a modular and open software defined radio (SDR) platform built around Coherent Logix’s ultra-low power, extremely-high performance, reconfigurable (on-the-fly) HyperX processor. This real-time reconfigurable low-power processor for signal processing provides SAGE the flexibility to rapidly develop and deploy a variety of advanced algorithms for GPS processing, anti-jam, multipath suppression, receiver sensitivity improvements and power conservation. BENEFIT: The development of the SAGE will enable the DoD to provide every soldier with a power-efficient and cost-effective adaptive interference mitigation solution for robust, military-code GPS receivers. The adaptive reprogrammability make it suitable for applications in small UAVs, small robotic vehicles, and small guided munitions. Exploiting Coherent Logix’s ultra low-power, extremely high-performance HyperX processor will provide the Warfighter with a cognitive and adaptive GPS plus Interference Mitigation solution that will optimize GPS performance parameters such as position accuracy, receiver sensitivity and power dissipation across a wide range of reception conditions. Last, the resulting technology facilitates an open system and promotes an industry friendly eco-system to facilitate innovation and value added product solutions that are critical to the upcoming Military GPS User Equipment (MGUE) program supporting the Common GPS Module (CGM) concepts.
