Paper Abstract

We present first experimental results with an imaging LIDAR developed for rendezvous and docking of a spacecraft and a passive sample canister in the Martian orbit. The LIDAR covers a field of view of 20 by 20 degrees at a range of 5,000 m down to 1 m to cooperative targets. The frame rate is 1 Hz. In close range, the canister's position is calculated from the measurement results of the individual cooperative targets attached to its surface in known configuration. The design of the LIDAR is aimed at low weight and power consumption employing a fiber laser and a small receiver aperture resulting in a small scanning mirror. The scanning concept is based on a Gimbal-mounted scan mirror avoiding scan gaps for optimally exploiting the laser's power and minimizing the scan time. Sensor concept and technologies can be also be adapted for future Planetary or Lunar Lander applications.
