Manchester encoder–decoder for optical data communication links

SpaceWire is a point-to-point bit shipping protocol for high-speed data communication links and networks providing equipment compatibility and seamless component reusability. It has found great application in many space missions reducing the development cost, offering architectural flexibility and improving reliability. This chapter delves into the standard describing the SpaceWire, focusing on the lower levels that play a key role in the electromagnetic behavior of the system and concern cable assemblies, shielding, bonding, and grounding. Findings regarding emissions affecting spacecraft components are presented as well as other EMC issues that have an impact on the system performance. Recent developments and upcoming updates to the standard are also presented and discussed.

This paper presents a communication network for a squadron of unmanned aerial vehicles (UAVs) to be used in the scanning rocket impact area for Barreira do Inferno Launch Center—CLBI (Rio Grande do Norte, Brazil), aiming at detecting intruder boats. The main features of communication networks associated with multi-UAV systems are presented. This system sends information through Wireless Sensor Networks (WSN). After comparing and analyzing area scanning strategies, it presents the specification of a data communication network architecture for a squadron of UAVs within a sensor network using XBee Pro 900HP S3B modules. A brief description is made about the initial information from the construction of the system. The embedded hardware and the design procedure of a dedicated communication antenna to the XBee modules are presented. In order to evaluate the performance of the proposed architecture in terms of robustness and reliability, a set of experimental tests in different communication scenarios is carried out. Network management software is employed to measure the throughput, packet loss and other performance indicators in the communication links between the different network nodes. Experimental results allow verifying the quality and performance of the network nodes, as well as the reliability of the communication links, assessing signal received quality, range and latency.

Multiple Channel

Electronics for burst mode data communication over an optical data link will contribute to wider acceptance of photonic technology. This paper describes the concepts and difficulties inherent in burst mode optical communication systems, and proposes a new solution employing an ultra-high speed, high accuracy peak detector. Sensitivity penalties associated with this technique are reviewed. The method was implemented in an optical receiver with dc to 500 Mb/s operation, and at 200 Mb/s, demonstrates an isolated pulse sensitivity of −29.5 dBm, and pulse width distortion less than lns. An example application, the Multiple channel Optical Data LINK (MODLINK), is described: a fully dc-coupled, 12 parallel channel digital data link system designed for high speed optical fiber communication at bit rates ranging from dc to 200 Mb/s per channel, applicable at distances of centimeters to over 3 km.
