OWLS: a ten-year history in optical wireless links for intra-satellite communications

Using Light-Emitting Diodes for intersatellite links

“…LEDs have been evaluated and flown in orbit for intrasatellite communication between internal assemblies onboard satellites [17], but have not been used for intersatellite communication with LED intersatellite links.…”

“…Return-to-zero (OOK-RZ) was recommended for its simplicity and ease of use [17]. Assuming the rise and fall times are included in a conservative pulse width of 600ns, a raw bitrate of over 1.5Mbps can then be supported before coding overhead to decrease errors.…”

Free-Space Optical Communications in Vehicular Networks Using Rectangular Guiding Models

“…PTICAL wireless communication (OWC) has become established using both infrared and visible light [1][2][3][4][5][6][7], and the utilization of OWC in confined vehicular environments was proposed by Green et al [8]. Both the doors and the vehicle frame form potential waveguiding structures that are free of sun and ambient light.…”

Wireless optical communications for intra-spacecraft networks based on OCDMA with random optical codes

“…In recent years, spacial agencies have shown a growing interest in optical wireless as an alternative to wired and radio-frequency communications [1,2]. The use of these techniques for intra-spacecraft communications reduces the effect of take-off acceleration and vibrations on the systems by avoiding the need for rugged connectors and provides a significant mass reduction.…”
