“…While having very low mass and size as well as good transmission range, these transceivers utilized infrared LEDs (IREDs), which have been shown to suffer from radiation-induced displacement damage depending on the device's construction [4] [5]. The resulting drop in LED effi ciency could cause signifi cant degradation of range, data rate, or power effi ciency.…”

This paper summarizes the on-going work at the Johns Hopkins University Applied Physics Laboratory (JHU/APL) towards implementation of a free-space optical bus for small spacecraft applications. After reviewing the current state of the art as well as previous work at JHU/APL, a comparison of several protocols, including USB, RS232, 10Mbit Ethernet (IEEE 802.3) is summarized, with Ethernet being the chosen protocol. Component selection is discussed in the context of radiation environments. Finally, a prototype point-to-point link that was assembled using COTS hardware and several different transmitting elements is described. It was found that the key technical challenge that remains is the receiver sensitivity. Plans for follow on work to complete the link are also summarized.

“…The optical components [31][32][33] are more prone to space radiation effects; therefore, their testing is necessary before use. The optical components mostly suffer from the displacement damage effect [28][29] and the device tolerance to this damage can be tested by exposing it to the radiation source with and without bias and measuring the performance. The components were evaluated with various The percentage decrease after the exposure of radiation dose of 10 times the mission life is plotted in Fig.6.…”

The ever-decreasing size of the small satellites with more demanding payloads has opened new research areas to investigate innovative onboard data handling solutions. The paper presents the use of optical intra satellite communication using discretely designed transceivers. The transceiver can handle large variations in the received photocurrents and implements filtration against the ambient light. The designed transceiver has been tested with selected optical components including infrared diodes, photo detectors and optical guides to validate its functionality. The displacement damage testing on selected optical components was performed to validate their suitability for use in space. The experimental communication schemes have been presented for free space as well as glass fiber based intra spacecraft communication. 10% of the total satellite mass [38]. The added harness mass puts additional constraints on the cost of the mission launch and fuel requirements. Therefore, the space industry is considering novel and out of the box solutions for future small satellite missions. The European Space Agency, in particular, has initiated projects to implement optical communication for inter as well as intra spacecraft communication [39-40]. As part of the inter-satellite communication activities, the first optical inter-satellite communication link was successfully established between the SPOT-4 and ARTEMIS satellites, proving the concept of utilizing optical communication technologies. In 2006, the Japanese Space Agency (JAXA) demonstrated a bidirectional optical link between its satellite and ARTEMIS. A number of in orbit communication solutions have been demonstrated on-board the spacecrafts in the last few years [10-15]. Although there have been initiatives of light based communication for relatively larger satellites, there has not been much research and development of implementing optical communication for relatively smaller satellites. A trade-off analysis of wire and wireless communication solutions for small spacecrafts was performed based on the recent literature review [20-27]. The traditional wired approach is least affected by the radio interference, achieves high security and reliability but at the expense of harness complexities.

“…Because radiationinduced attenuation (RIA) bands in fibres are centred in the ultraviolet, fibres have better radiation resistance at longer wavelengths [6]. However, the radiationhardness of laser-optimised 50-µm graded-index fibres was recently tested in the ESA' s SpaceFibre project [7].…”
