Abstract : To do absolute optical transmittance measurements between two ships requires that the light source and the receiver reciprocally track each other. This report describers the tracker equipment designed to do this measurement and the tracking ability test results of January 1982. We demonstrated a dynamic tracking error of 20 microrad in both azimuth and elevation. The modified Nike-Hercules tracker has a 32 in. primary. The receiver includes a modified 60 in. searchlight.
