The performance of a closed loop controlled Mach-Zehnder interferometer for optical DPSK communications at 2.67 Gbps in the presence of simulated Doppler and atmospheric scintillation effects is presented. The applied frequency slew rate during testing exceeded those expected for LEO to ground or GEO, aircraft to GEO and LEO to LEO satellite lasercom links. The applied scintillation time series were derived from data collected during recent LEO to ground communications between the NFIRE satellite and the ground station at the European Space Agency observatory in Tenerife, Spain. Results are presented for a range of received power levels representing high and low SNR conditions anticipated for real lasercom systems.
