TABLE 13. [UTC - GLONASS TIME] The GLONASS satellites disseminate a common time scale designated as 'GLONASS time'. The relation between UTC and GLONASS time can be written as : [UTC - GLONASS time] = C1 (modulo 1 s). From his current observation of both the GPS and GLONASS satellite systems Prof. P. Daly, University of Leeds, establishes and reports [GPS time - GLONASS time] at ten-day intervals, together with the standard deviation s of his daily GLONASS data. C1 is then derived using [UTC - GPS time] of Table 12.
