The Miniature Optical Communication Transmitter is a NASA-sponsored compact, pulsed optical communication system for distant, power-constrained small satellites. A pulse-based scheme is driven by an FPGA-based Software-Defined Pulse Modulator. In addition to optical communication, the MOCT also has potential capabilities in precision clock synchronization and navigation beyond Earth orbit. This work is a continuation of results presented at the 2015 SmallSat conference.1 A novel combinatorial delay generation technic allow a 10-fold increase in timing resolution and a similar improvement for delay uncertainties compared to previously reported results. The Laser system prototype is now complete and can operate with some amplification
