Optical Communications Technologies for High Data Volume Returns from Deep Space
نویسنده
چکیده
NASA communications roadmaps look to space based optical communications to fulfill future high data rate link requirements with minimal spacecraft burden and freedom from current RF spectrum restrictions. Efficient optical links for data rates from 10’s to over 1000 megabits per second require complementary and synchronized development of numerous subsystem technologies. We report recent developments and performance of Serial Concatenated Pulse Position Modulation coding, high data rate pulse position optical modulators, high power laser amplifier, efficient photon counting detector, and high background (daytime) photon counting receiver technologies for the photon starved channel

Deep-space optical communications is an active area of research at JPL. Optical communications is being pursued as an alternative to RF communications, because of the relatively low mass, volume, and power requirements and the potential for increased data rates. The emphasis of current deep-space optical communications research at JPL is in gaining ground-based receiver experience, as a precurs...
متن کاملNASA’s Deep-Space Telecommunications Road Map
With the advent of faster, cheaper planetary missions, the coming decade promises a significant growth in the number of missions that will be simultaneously supported by NASA’s Deep Space Network (DSN). In addition, new types of missions will stretch our deep space communications capabilities. Ambitious outer planet missions, with extremely tenuous communications links due to their great distan...
متن کاملCost and Performance Comparison of an Earth-Orbiting Optical Communication Relay Transceiver and a Ground-Based Optical Receiver Subnet
Optical communications can provide high-data-rate telemetry from deep-space probes with subsystems that have lower mass, consume less power, and are smaller than their radio frequency (RF) counterparts. However, because optical communication is more affected by weather than is RF communication, it requires groundstation site diversity to mitigate the adverse effects of inclement weather on the ...
