Abstract
This paper presents the estimation of receiver code bias of Global Positioning System (GPS) continuously operating reference stations (CORS) over Malaysian region, MyRTKnet stations. In this study, we used the Bernese software and adopted the algorithm from IONOLAB method to estimate the receiver code bias (RCB). It has been found that the RCB from Bernese and IONOLAB show a good correlation with RCB from the International GNSS Service (IGS) analysis centre with R2 values are within 0.3 ns to 0.7 ns and 0.6 ns to 0.9 ns, respectively. The estimation of RCB for MyRTKnet shows that there are no latitudinal dependencies of the RCB values. It has been found that 99% of the receivers have standard deviation below than 1 ns for both methods. It also found that both methods can provide reliable RCBs value as the mean vertical total electron content (VTEC) computed using RCBs from both methods shows a similar trend and fluctuation from IGS global ionospheric maps (GIM). Hence, it is suggested that further studies can be carried out using both methods to study the variations of RCB for a longer period to improve total electron content (TEC) estimation.
