• This paper presents the development of a miniature multifunctional GPS receiver at NASDA. The design and implementation method for a spaceborne GPS receiver has been investigated, and a breadboard model of a parallel signal search system incorporating matched filtering, an essential technique for next-generation GPS receivers, has been manufactured. The time to acquisition (TTA) of a GPS signal was measured on the breadboard model using a GPS simulator. The test results of the trial product show that TTA is within 60 msec, and time to first fix (TTFF) of the navigation calculation in a low-altitude orbit is within 5.3 min in the worst-case scenario.
