FIELD: antenna measurements. ^ SUBSTANCE: method can be used for inspection of directivity diagrams of antenna systems of different radio systems. Method is based upon measurement of signal amplitude of point radio signal source, disposed in far area of antenna, and angular coordinates of the source. Several navigation satellites of global positioning systems GPS are used. Data on amplitude of radio signals of navigation satellites, their angular coordinates and preudorange to navigation satellite are presented in Internet in form of files in RINEX formats. Rows of values of radio signal amplitudes are formed by means of processing of RINEX files for any navigation satellite depending on its angular coordinates. Rows are selected of set of rows achieved for angles of location of navigation satellite being bigger than 10° which are controlled for factors being proportional to pseudorange till getting corresponding to navigation satellites. Rows of controlled values of amplitude for all the navigation satellites are coherently supposed to adding and averaging. ^ EFFECT: improved precision; reduced time of measuring of directivity diagram; reduced cost of testing. ^ 6 dwg |
