Abstract

Sensor networks based on Impulse-Radio Ultra Wideband (IR-UWB) technology have gained traction in fields where precise localization and robust communication links are required. In spacecraft and launchers these networks can be used to connect sensors to a central on board computer or to provide a communication link between the different subsystems. This contributes to a reduced cable harness, a key driver in overall spacecraft mass and design complexity. A problem in low power wireless sensor networks is the low data throughput. This paper presents a high data throughput extension to an 802.15.4 standard compliant MAC layer for Ultra Wideband to accommodate for e.g. payload data acquisition or software update distribution to the different subsystems. Where the previous protocol allowed for a mere 3 kB/s of throughput in a typical configuration, the augmented MAC layer now is able to achieve up to 341 kB/s.
