Abstract
Comparison of high-performance time scales generated by atomic clocks in laboratories of time and frequency metrology is usually performed by means of the Common View method. Laboratories are equipped with specialized GNSS receivers which measure the difference between a local time scale and a time scale of the selected satellite. Every receiver generates log files in CGGTTS data format to record measured differences. In order to calculate time differences recorded by two receivers, it is necessary to obtain these logs from both receivers and process them. This paper deals with automation and speeding up of these processes.

GNSS stands for Global Navigation Satellite System
There are special receivers which are primarily focused on the transfer of the time and frequency
This paper presents a new approach which counters these disadvantages and produces results faster
Summary
GNSS stands for Global Navigation Satellite System. It is a term that is used internationally for satellite navigation systems that provide autonomous geospatial positioning with global coverage. The advantage to having access to multiple satellites is accuracy, redundancy, and availability at all times. If the line of sight is obstructed, having access to multiple satellites is a benefit. Thanks to the high precision of the time scale of the satellite system it is possible to use receivers as a time reference and time measurement devices. There are special receivers which are primarily focused on the transfer of the time and frequency. These devices use code and phase measurement on several channels using one or more of the satellite system variants
