High-performance Extremely Low Power GPS Receiver Card (HELPR)

Coherent Logix, Incorporated (CLX) proposes to develop a military High-performance Extremely Low Power GPS Receiver (HELPR) system suitable for use with soldier handheld PDAs, micro-UAVs, and unattended ground sensors. HELPR will support form factors similar to existing PDA cards for civilian GPS receivers, but will achieve much greater position and time accuracy by receiving and processing military GPS signals on both the L1 and L2 frequencies. This effort leverages a much larger program at CLX to develop extremely high-performance per watt, reconfigurable (on-the-fly) digital signal processor (DSP) CMOS integrated circuits based on its HyperX Technology. Utilizing a reconfigurable DSP for IF signal processing and code correlation, HELPR will have the flexibility to use any and all codes broadcast by satellites and terrestrial stations for radio navigation, and will support a wide variety of power conservation and noise/interference mitigation strategies.
