¿µ¹®³»¿ë¿ä¾à | To obtain the service provider licence of DGNSS (Differential Global Navigation Satellite System), it is essential that the performances of established DGNSS station, such as ERP(Effective Radiated Power) and transmission frequency, should satisfy the requirements of the national radio regulatory authority. Accordingly, this standard describes the calculating methods of various systems parameters of DGNSS system. In specific, the measurements of DGNSS signal strength and the calculations of radiated power, antenna effective height, total resistance, earth/ground resistance, antenna capacitance, quality factor, and bandwidth are presented. Also, for the succinct illustration of the calculating methods, several situational examples are represented. | ||
