Next Generation Software-based GPS Receiver for Real-World Applications

F. Yuen, Z. Liu

Abstract:	This paper introduces a next generation software-based GPS receiver technology that is capable of providing meters level accuracy, independent raw measurements and PVT (position, velocity, time) solutions using as little as 1-2ms (millisecond) of I/Q samples. This unprecedented performance is based on a revolutionary patent pending technology called Deep-R™. Unlike conventional software based processing techniques, Deep-R™ does not require an initial position. Initial time tag can be provided by an external time source with errors up to 10’s of minutes. Deep-R™ does not employ the use of tracking loops, as a result, the problems with maintaining lock in the tracking loops are completely eliminated. When used in streaming mode, Deep-R™ is capable of generating 500Hz of independent raw measurements and PVT solutions. Deep-R™ provides a low-cost solution for GPS positioning without the need for significant processing power and expensive hardware. Instead of using a dedicated baseband processor, Deep-R™ employs only a low-cost RFIC to extract, down-convert and demodulate GPS signals. Processing is performed in software using a general purpose processor such as a microprocessor or a digital signal processor. This flexible approach significantly reduces power consumption and is therefore ideal for modern consumer electronics.
