Science Hardware Used:

  • LCOT-N as an assembly;
  • LCOT-I internal unit;
  • LCOT-N cable reel;
  • Set of cables.

Flight Equipment Used:

  • Laptop A31P (RSE-LCS);
  • Universal work station.

Expected Results:

Development of the laser communication system and the data reception-transmission procedure with a capability of LCOT modification to increase the power potential and the capacity without the significant reprocessing of the main structural units, as well as through the use of the additional receiving or transmitting modules and the added spectral receiving or transmitting channels.

Experiment Results:

Telemetry information on LCOT operation and data on the communication channel performance in different experiment conditions.
