This article concerns the problem of difficulty in correct indoor Global Positioning System (GPS) signals reception due to attenuation. Radio signal repeaters are proposed as means to solve this problem. Firstly, the GPS signal characteristics are described, emphasizing their low power in the point of reception. In the second part, various applications of GPS signal repeater, where indoor GPS signals reception is required, are mentioned. Afterward, types of radio signal repeaters are described. In the fourth part, a practical realization of analogue GPS signal repeater is presented. The elements of this device are shown and described. Next, the repeater measurement configuration and methods are described. Following, measurements results of parameters, such as position error and carrier to noise power density ratio, are shown. In conclusion, the possibility to use the built analogue GPS signal repeater is assessed.
