Abstract
An improved global positioning system satellite signal acquisition method and device. The method and device of the invention reduces the number of operations in the block correlation used in determining Doppler frequency and time of the received GPS C/A and P(Y) codes. Reducing the number of operations in block correlation increases acquisition speed and reduces energy requirements, aspects conducive to commercial and military hand held GPS receivers.
