Abstract
This study examines the accuracy performance of GNSS receivers when connected to the continuous reference station (CORS) network managed by Thailand's Department of Lands (DOL) and the Royal Thai Survey Department (RTSD), focusing on the impact of inserting SIM cards between the receiver and controller. Three GNSS receivers were tested: two from the same brand but different models, and one from a different brand. The research investigates how the CORS network's effectiveness and the method of SIM card insertion influence the data accuracy and receiver stability. The results show that data stability improves when connected to the RTSD's CORS network, with more consistent and reliable performance observed when SIM cards are inserted directly into the receiver. In contrast, inserting the SIM card into the controller led to significant instability in the GNSS data. These findings highlight the importance of both network choice and proper SIM card placement for optimal GNSS performance.
