Spaceborne GPS receiver is a very useful component which enhances spacecraft autonomy, so the requirement for receivers is getting advanced. Moreover, in GPS modernization, new civil codes on L2 and L5 frequency bands will be added. In this study, a new generation spaceborne GPS receiver is investigated, which can track more 24 GPS satellite signals including the L2 new civil code (L2C). In this paper, the design result and target specification of a new generation dual frequency spaceborne GPS receiver, utilizing legacy L1C/A signal and new L2C signal, are summarized. Next, L2C signal acquisition and tracking correlator implementation and device's test results are shown. The functional model of a new generation dual frequency spaceborne GPS receiver, including L2C signal correlator, was designed and manufactured. Finally, several tests for spaceborne GPS receivers were conducted by GPS simulator and the target specification was validated by the evaluation of these test results.
