SLCSAT (Submarine Laser Communication Satellite) Communication System Design Study
Abstract
This report summarizes the results of a Lincoln Laboratory study of issues affecting Submarine Laser Communication Satellite (SLCSAT) implementation. The study compares alternative SLCSAT downlink implementations using semiconductor and solid-state lasers in terms of the satellite transmitter power required to provide a given level of communication service. Signal coding is applied to increase transmitter design flexibility by accommodating a wider range of peak-to-average power trade-offs. Adaptive signaling structures which allow more efficient use of transmitter optical power in the face of channel variations are illustrated. Receiver atomic resonance filter alternatives compatible with operation in solar Fraunhofer lines are discussed. Power efficient tunable transmitter technologies, particularly frequency doubled AlGaAs diode lasers, are found to be very attractive. SLCSAT system size estimates are presented for the various technologies presented. High leverage SLCSAT technology development areas are identified.
