Global Positioning System (GPS) is a space-based radio navigation satellites service that provides universal access to position, velocity and time information. Nowadays, GPS has emerged as a universal cornerstone for much of our technological infrastructures. However, the GPS signals can be corrupted, either intentionally or unintentionally by strong interfering sources such as microwave transmission towers, radar frequency and multipath. These anomalies can affect the accuracy and the integrity of GPS applications particularly in the field of surveying applications where positioning at the highest accuracy is greatly demanded. This paper highlights several tests conducted to assess the performance of Virtual Reference Station Real-time kinematic (VRS-RTK) observation using MyRTKnet under difference sky viewing conditions. These tests were designed to provide an empirical evaluation of both initialization failure probability and the range of the subsequent errors in the observed coordinates under varying observation conditions. Some experimental results are presented and discussed.
