Satellite Positioning System with Active Antenna for QZSS

A satellite positioning system with an active antenna for the quasi-zenith satellite system (QZSS) was examined. The advantages of the antenna are the low price, the lightness, and the miniaturization compared to those of the conventional active antenna for QZSS. From the experimental result of the satellite positioning, we show that the proposed system has high accuracy without a location information from the electronic reference point.
