説明 DESCRIPTION

ANTTOOL is an analysis tool for GPS antennas/receivers. ANTTOOL estimates GPS antenna parameters. The parameters include antenna phase center offsets, antenna phase center variations, carrier-phase multipath, code multipath, carrier to noise power density. Please input target antenna/receiver RINEX observation data, reference antenna/receiver RINEX observation data (dual-frequency) and RINEX navigation message file. The reference antenna must be placed in the vicinity of the target antenna.

実行環境 ENVIRONMENT

Matlab 6 or higher version of Matlab. Tested on Windows version of Matlab 6.5.1 and 7.4 (R2007a)

インストール手順 INSTALL
