Abstract:	This paper describes the results of APL (Airport Pseudolite) flight experiments conducted for the first time in Japan. These experiments had been collaborated with Japan Civil Aviation Promotion Foundation (JCAPF) and Electronic Navigation Research Institute (ENRI). This paper shows that the accuracy of the DGPS (Differential Global Positioning System) positioning with the APL, the APL code tracking bias and the near-far problem associated with APL signal strength. The accuracy of vertical positioning was improved using the APL. Although the pseudorange had code tracking bias and DGPS correction was generated by a single reference receiver. Smoothing for pseudorange was internal with a time constant of 5 seconds. The tropospheric effect for the APL code should be corrected using suitable model. The effect of near-far problem was checked in the field and found out that its effect was very small in the condition of the low 2.733% APL duty cycle pulse sequence.
