- Abstract
The main characteristic of the communication between spacecraft subsystems is the communication reliability. The performance growth of the low power wireless network may lead to their use for avionics communication. The ISA100.11a standard by the time, frequency and space diversity allows the implementation of a robust network and can reach the communication requirements for the spacecraft equipment. This paper analyses the resource allocation in an ISA100 network, for achieving the same throughput and latency as existing wired MIL1553B or CAN buses. Based on the this study the ISA100 network, on the current specifications, does not achieve the spacecraft communication requirements, but by adopting the UWB as the physical layer it can become a strong competitor for intra-spacecraft communication.
