Performance evaluation of low-cost GNSS receiver using MADOCA corrections with the Static Precise Point Positioning (PPP) mode in Thailand

Abstract

Multi-GNSS Advanced Demonstration tool for Orbit and Clock Analysis (MADOCA) from the Quasi-Zenith satellite system (QZSS) covering the Asia-Oceania region. It aims to meet the need to provide real-time positioning services (PPP-Realtime). In Thailand, the satellite QZSS will be seen in the range of 15 - 60 degrees allowing it to receive correction signals from the QZSS satellite system directly. This research aims to study on performance evaluation of low-cost GNSS receiver using MADOCA corrections with the Precise Point Positioning (PPP) mode in Thailand. To demonstrate the efficiency and positional accuracy of the MADOCA correction system for real-time positioning services, this correction focuses on processing in a Precise Point Positioning static mode for the static point test resulting in the correct value horizontal and vertical root mean square error in centimeters. This shows good performance for Low-cost receivers in combination with MADOCA correction in Thailand area.
