Abstract
Monitoring kvality sieťového riešenia SKPOS prešiel od svojho vzniku výrazným vývojom. Spočiatku bola služba SKPOS monitorovaná iba prostredníctvom riadiaceho softvéru služby. V roku 2013 bol vyvinutý nezávislý monitoring kvality sieťového riešenia založený na virtuálnom princípe, ktorý umožnil priebežné vyhodnocovanie presnosti poskytovaných korekcií. Tento prístup sa neskôr rozšíril aj na monitoring zahraničných RTK služieb v rámci pracovnej skupiny pre kontrolu kvality služieb iniciatívy EUPOS. Od roku 2020 bol systém doplnený o šesť fyzických monitorovacích staníc. V roku 2022 bol v rámci európskych aktivít odprezentovaný nový prístup validácie referenčného rámca RTK služieb – tzv. grid-check. Tento princíp bol aplikovaný aj v rámci služby SKPOS a umožňuje priestorovú analýzu odchýlok v pravidelnej mriežke bodov. Príspevok prezentuje vývoj metodík monitoringu kvality SKPOS, porovnanie výsledkov virtuálneho monitoringu, fyzických monitorovacích staníc a grid-check prístupu.
Since its inception, the monitoring of the quality of the SKPOS network solution has undergone significant development. Initially, the SKPOS service was monitored solely through the service’s control software. In 2013, an independent quality monitoring system based on a virtual principle was developed, enabling continuous evaluation of the accuracy of the provided corrections. This approach was later extended to the monitoring of foreign RTK services within the Quality Control Working Group of the EUPOS initiative. Since 2020, the system has been supplemented with six physical monitoring stations. In 2022, a new approach to the validation of the reference frame of RTK services – referred to as the grid-check was presented within European activities. This principle was also applied within the SKPOS service and enables spatial analysis of deviations on a regular grid of points. The paper presents the evolution of SKPOS quality monitoring methodologies and compares the results obtained from virtual monitoring, physical monitoring stations, and the grid-check approach.
