Analysis of the Skpos® users Initialisation Times

From the establishment of the Slovak real time positioning service (SKPOS^®), the reference stations’ observations, network solutions and outputs from the user communications with the service control software were set for archiving. Today we know that all those archived data have the potential to give us valuable information about the service’s character and quality and about the conditions during the performance of Real time Kinematic (RTK) measurements. After conducting some analyses, we are able to easily understand how important factors such as the number of satellites used, the state of the ionosphere, network solutions in the border zone, densification of the network, etc., can affect those measurements. For those purposes the users’ initialisation times derived from the archived National Marine Electronics Association (NMEA) messages are used in advance. As a tool for analysis the new Application for SKPOS® Monitoring and R
