PURPOSE:To enable a highly accurate testing with limited effect of temperature changes on the propriety of a test by enabling the supply of a beam angle correction signal within a Doppler navigator as sample and an output signal of a temperature detector to a tester through a connector connectable from outside. CONSTITUTION:A beam angle correction signal 7 and an output of a temperature detector 8 can be inputted into an input circuit 18 of a tester 12 in addition to a speed output from an output circuit 10 through connector and these data are digitized and inputted into an electronic computer 19. The electronic computer 19 corrects the nominal value of an antenna beam angle based on the set Doppler frequency, a beam angle correction data from the input circuit 18 and an antenna temperature data and executes speed calculations of separate shafts by the same formula with a microprocessor 11. The results as an expected value of speed are compared with speed outputs of the shafts inputted as digitized from the input circuit 18 and it is determined whether or not the error is within the prescribed allowable value. |
