Laser Tracking Reflector

NSSDCA ID: 1964-064A-03

Mission Name: BE-B
Principal Investigator:Dr. Henry H. Plotkin


The passive optical laser experiment, which consisted of nine panels on the spacecraft, was used to determine the spacecraft range and angle. Each panel was covered with 40 quartz cube-corner prisms that provided laser tracking capabilities for optical tracking studies. The ground-based optical transmitter was a pulsed 1-microsecond ruby laser. A photo detector determined whether the laser beam interrupted the spacecraft. The experiment operated as planned.
