The NOOSHA GPS-BB is a 16- channel C/A code baseband processor for use in NAVSTAR GPS satellite receivers.
The NOOSHA GPS-BB despreads & demodulates the 50 bps data stream embedded in the GPS signal and provides the estimated signal propagation and delays. Full position-velocity-time solution is then calculated.
The main feature of the designed GPS receiver is 90% power saving mode in which the power is saved by means of turning the system on & off periodically. After the navigation data is updated, the system can turn off the RF and baseband for 90% duty cycle. This feature of power saving is valuable in human scale applications.
