COMPARATIVE ANALYSIS OF SECOND ORDER CONTROL NETWORK USING DUAL TOTAL STATIONS: PRECISION ASSESSMENT AND ERROR ANALYSIS

This study undertakes a comprehensive comparative analysis of second-order control using dual total stations, focusing on precision assessment and error analysis. The research aims to investigate the efficacy of dual total stations in achieving precise second-order control, examining the impact of instrumental and procedural variables on accuracy. A mixed-methods approach combining field measurements, statistical analysis, and simulation modeling is employed. Findings indicate significant variations in precision across different instrumental configurations and measurement protocols. The study highlights the importance of optimized instrumental settings and rigorous procedural controls to minimize errors. For the purpose of this research twenty points (FPA55S to FPA 002T) were chosen for observation to allow for easy and simple demonstration and assessment. To ensure the reliability and precision of the control network, a detailed observation procedure was followed. This involved conducting observations at 20 control points, with measurements taken twice daily—once in the morning and once in the evening. This approach helps to account for any diurnal variations and enhances the overall accuracy of the measurements.Despite the widespread use of total stations, there is limited research on how different times of the day affect their measurement accuracy. The problem, therefore, is the need to understand how the performance of total stations varies between morning and evening observations and to determine which instrument provides more reliable measurements under these conditions. To achieve more accurate and consistent results, it is recommended to perform surveys in the morning when the measurements between the two instruments are more reliable.
