Performance assessment of Virtual RINEX for cadastral surveying in Thailand

Abstract

Nowadays, the Network-based Real Time Kinematic (NRTK) - Virtual Reference Station (VRS) technique has been being applied for the Cadastral surveying in Thailand. The concept of VRS begins from a Continuously Operating Reference Stations (CORS) streams the GNSS data to the control center then the rover receiver must be sending its approximate position to the control center via NMEA format. After that, the control center will simulate the Virtual Reference Station (VRS) at that approximate position. However, the VRS technique can also operate in post processing mode, by generating the Virtual- RINEX data via the CORS WEB network website. In this research, the assessment of the VRS technique in post processing mode for the cadastral survey application was investigated.
