Moreover, because of GPS modernization, new civil signals on L2 and L5 frequency bands will be added. A new generation of spaceborne GPS receiver is studied, which can track 12 GPS satellite signals including the new L2 civil code (L2C). In this paper, the development and test results of an electrical model of a dual frequency spaceborne GPS receiver are summarized. The electrical model has 12 L1C/A and 12 L2C(C/A) channels, and is utilizing embedded dual-frequency navigation software., 資料番号: AA0049054049, レポート番号: JAXA-SP-05-008}, title = {小型高機能GPS受信機の研究}, year = {2006} }
