摘要

The paper presents study results about determination Wide-Lane Hardware Delays in GPS system. For this purpose GPS data from RYKI reference station were used. Melbourne-Wuebbena linear combination were applied for estimation WHD. Computations were executed in SciTEC software, which code source was written in Scilab 5.4.1. Firstly, results from SciTEC software show that WHD are very stable over few days. In this paper 4 experiments are presented. Accuracy of WHD in submitted paper is less than 2 ns. Over few days, magnitude order of mean SWHD is ± 1 ns, what corresponds to 0.3 cycle of wavelength in L6 combination. Difference between maximum and minimum value of SWHD over 6 days is about ± 2.5 ns. RWHD over few days are so very stable, with mean value about -0.154 ns. Standard deviation of daily repeatability RWHD parameter is less than 0.07 ns, what corresponds to 2% of wavelength in L6 combination.
