Researchers at the University of Tehran have developed indigenous software for providing real-time corrections for networks, precise positioning service and online processing of GNSS observations.
According to various news reports, the software is a modern, secure, and intelligent platform for processing observations from global positioning satellites, including GPS, Galileo, BeiDou and GLONASS.
Developed as a practical tool for surveyors, engineers, researchers and organizations in the field of satellite data monitoring, the software is intended to replace imported software and reduce dependence on foreign technologies. It has been tested by the network of permanent stations of the National Iranian South Oil Company.
The system processes observations using static, PPK, PPP and SPP methods, as well as observation quality control and enables the implementation of various positioning methods and real-time monitoring of ionospheric and tropospheric effects.
It supports all GNSS data types and can connect to reference stations in both client and server modes. It supports all existing and future GNSS signals and can handle at least 50 permanent stations and 200 users simultaneously. It also provides phase ambiguity resolution for baselines up to 70 kilometers.
Other technical features include providing a relative planimetric accuracy of 2 cm and a height accuracy of 3 cm using the static method with a maximum setup time of 15 minutes, a relative planimetric accuracy of 4 cm and a height accuracy of 5 cm using PPK and NRTK methods, and delivering corrections with a maximum permissible latency of 0.5 seconds.
The software has the capability to connect to reference stations through serial, TCP, and UDP ports, supports NTRIP protocol versions 1 and 2, displays an online map with a Google Map-like background, allows for viewing the location, status and information of CORS stations and active users, and enables generation of KML outputs.
