Abstract
Testing and qualification of a commercial dual-frequency GPS receiver has been done for a joint project by CSA and JAXA. This paper reports the results of performance assessment of the NovAtel OEM4-G2L dual frequency receiver with modified firmware. The signal simulator tests for LEO mission are performed, and the initial tracking/acquisition performance, single point navigation accuracy and the effect of the deterioration of the L2 (Pseudo-Y) signal on the navigation accuracy are evaluated in this study. Furthermore the comparison of a navigation performance between the NovAtel OEM4-G2L and the JAXA micro GPS receiver developed based on a single frequency terrestrial GPS receiver is discussed.
