The software has been fully designed and developed at the University of Tehran with the purpose of fully replacing imported software and reducing dependence on foreign technologies.
It has been tested by the network of permanent stations of the National Iranian South Oil Company.
The software is a modern, secure, and intelligent platform for processing observations from global positioning satellites, including GPS, Galileo, BeiDou, and GLONASS.
The system possesses the capability for automated and accurate processing of 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.
The software, developed as a practical tool for surveying engineers, researchers, and organizations in the field of satellite data monitoring, supports all GNSS data types and features diverse capabilities, including connecting to reference stations in both client and server modes, full support for all existing and future GNSS signals, the ability to handle at least 50 permanent stations and 200 users simultaneously, and provide phase ambiguity resolution for baselines up to 70 kilometers.
It has other technical features, including 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 generating KML outputs.
Other features of this system include support for various data formats such as RTCM2.x, RTCM3.x, RINEX 2.x, RINEX 3.x, and raw data; data archiving; no limitation on the number of RTCM inputs; modeling corrections and transmitting them using NEAREST and VRS algorithms; and the ability to analyze and perform quality control of data with graphical displays and generation of specialized reports.
It has advanced capabilities such as the modeling of error behavior in both state space representation and observation space representation; recording and viewing logs of all system events, user activities, and station operations; post-processing raw data in differential mode for static and stop-and-go scenarios; point-based processing of data in SPP and PPP modes; and analyzing the behavioral models of ionospheric and tropospheric effects by extracting STEC and ZTD parameters.
The ability to monitor the coordinates of reference stations in real time, record and display their change history, and utilize an advanced service portal with varied access levels for users has made this software a comprehensive, indigenous system in the field of precise satellite positioning.
