There are several geodesic methods of area measurement. The following article provides description of a non-conventional method which involves the usage of satellite navigation devices. Based on a practical research, the accuracy of the method is being estimated. The analysis of different measuring conditions and factors, regarding their effect on accuracy, is made. The suitable areas, where the method could be used, are mentioned. In particular, the possibility of water surface and drainage area measuring is examined with the usage of previous theoretical base. In addition, the results of a recent field check covering such type of areas are presented in the article.
