Data Analysis for GOPEX Laser Communications Experiment
This paper describes the data analysis based on the image frames received at the Solid State Imaging camera of the Galileo Optical-communications from an Earth-based Transmitter demonstration conducted between December 9 and December 16 of 1992.

GOPEX: A Laser Uplink to the Galileo Spacecraft on its Way to Jupiter
In the Galileo Optical Experiment (GOPEX), optical transmissions were beamed to the Galilieo spacecraft by Earth-based transmitters at Table Mountain Observatory (TMO), California, and Starfire Optical Range (SOR), New Mexico. The demonstration took place over an eight-day period (December 9 through December 16) as Galileo receded from Earth on its way to Jupiter. At 6 million kilometers (15 times the Earth-Moon distance), the laser beam sent from Table Mountain Observatory eight days after Earth flyby covered the longest known range for laser transmission and detection.

A Deep Space Optical Communications Demonstration with the Galileo Spacecraft on its Way to Jupiter (abstract)
The GOPEX (Galileo Optical communications from an Earth-based transmitter) demonstration was performed from transmitter sites at Table Mountain Observatory, CA and Starfire Optical Range, NM. The experiment was done over an eight day period, December 9 through December 16 as Galileo receded from Earth on its way to Jupiter. At a range of 6 million kilometers (15 times the Earth-Moon distance), the transmission from Table Mountain Observatory eight days after Earth-flyby represents the longest range for laser transmission and detection.
