Position-fixing using the USSR´s GLONASS C/A code

Preliminary results have been produced showing the kind of accuracy and precision that might be expected with GLONASS satellites using a simple, digital, sequencing C/A code receiver measuring code phase only. The figures presented lead to the conclusion that GLONASS is capable, when operated with C/A code phase in the same manner as NAVSTAR GPS (Global Positioning System), of the same level of performance. In terms of position-fixing, a position fixing capability using code phase only and signal averaging, is observed which is well within the quoted accuracy of 100 m, and is probably on the order of 10-30 m. The current status of the GLONASS system is reviewed, and signal transmission and reception features are examined
