Abstract：As its signals are blocked or interfered ,satellite navigation is limited in some locations ,which can in a way be supplemented by pseudolites as an easy and effective means of augmentation .Through the study of the principles of pseudolite-augmented satellite positioning technology and starting with the GDOP and receiver jam-to-signal ratio ,the effec-tiveness of pseudolite-augmented satellite positioning and several issues for attention in the application of pseudolite augmen-ting are analyzed .The simulation shows that as long as the pseudolites are well arranged ,they can effectively improve the graphics fabric of the satellite positioning as well as its positioning precision and anti-jamming ability .
Keywords：pseudolitepositioning principlegeometric dilution of precision(GDOP)anti-jamming ability
