CONTROL OF ATOMIC CLOCK OF GLOBAL POSITIONING SYSTEM (GPS) OR GLOBAL NAVIGATION SATELLITE SYSTEM (GNSS) BASED ON NUMBER OF LEVELS, AND/OR NUMBER OF LIMITS AND/OR NUMBER OF STABILITIES Russian patent published in 2018 - IPC G04F5/14 

Abstract RU 2665014 C2

FIELD: measuring equipment.

SUBSTANCE: invention relates to measuring technology and can be used to control the atomic clock of the global positioning system (GPS) or global navigation satellite system (GNSS). For this purpose, the method includes establishing a measured difference between the atomic frequency standard (AFS) and a monitoring device. Also, the method includes simulating an estimated difference model between the atomic frequency standard (AFS) and a monitoring device and calculating the residual signal based on the measured difference and the estimated difference model. To achieve this, the first residual signal sensor is analyzed in a plurality of limits, each of which has an appropriate stability, specifying the number of over limits before the indication of one or more of the following: a phase jump, frequency jump and error due to acceleration. In addition, an analysis is carried out with the aid of the second sensor of the model parameter of the estimated difference in a plurality of limits, each of which has an appropriate stability, which specifies the number of over limits of the deviation limit before the deviation indication.

EFFECT: technical result is higher accuracy.
