Corresponding theoretical research has concluded that applying triple-frequencyobservation could performance of strength of equation system and improve the reliability of positioning result.Currently,BDS transmits navigation signal on three frequencies which enable the performance assessment of BDS using real triple-frequency observation.The characteristic of BDS triple-frequency observation is analyzed in respect of signal strength,multipath level and inter-frequency delay.Moreover,performance of BDS single-epoch relative positioning over different baseline length is assessed with real observation.The experiment results demonstrate that the fixed rate of triple-frequency ambiguity resolution is higher than dual-frequency case.It has also been concluded that application of triple-frequency observations has advantages over dual-frequency solution on reliability of fixed solution and decreased number of incorrectly fixed epoch.
