METHOD AND SYSTEM FOR WATCH CORRECTION Russian patent published in 2016 - IPC G01S19/07 

FIELD: physics.

SUBSTANCE: satellite clock error is defined for every navigation satellite on the basis of measurements of pseudorange code, carrier and broadcast errors of satellite clock supported by the network of receivers (S402). Differences are defined between calculated satellite clock errors and broadcast errors for every satellite (S406). Reference clock satellite is selected for every group navigation satellites. Note here that reference clock satellite features the difference in clock errors for this satellite group (S408). Correction is defined for broadcast clock error by application of the reference satellite clock error function to broadcast error for every satellite of one or more satellite groups (S410).

EFFECT: perfected determination of clocks correction at every network receiver.
