A spacecraft equipped with such technology is what we refer to as a federated negotiator spacecraft. A federated negotiator node acts as a middle man between spacecraft missions that would be otherwise unable to interoperate, acting as a protocol translator and enabling the opportunistic, ad-hoc exchange of resources envisioned in the FSS paradigm. This paper presents the ongoing efforts in the development of a negotiator spacecraft for federated satellite systems. These efforts include the implementation of Software-defined Radio (SDR) systems as an enabling technology for negotiator spacecraft. In particular, this work evaluates the use of commercial-off-the-shelf SDRs and GNU Radio as the technical solution to implement negotiating functions on federated spacecraft. The live signal received from ESTCube-1 is used for the demonstration of the protocol translation between SDRs, emulating different spacecraft operating at different protocols.

This new paradigm requires the utilization of several technologies in order to confer flexibility and re-configurability to communications systems among heterogeneous spacecrafts. The paper illustrates the results of the experimental demonstration of the value proposition of federated satellites through two stratospheric balloons interoperating with a tracking ground station through Commercial Off-The-Shelf Software Defined Radios (SDRs). The paper reports telemetry analysis and characterizes the communications network that was realized in-flight. It further provides details on an in-flight anomaly experienced by one of the balloons, which was recovered through the use of the federated technology that has been developed. The anomaly experienced led to the early loss of the directional link from the ground station to the affected stratospheric balloon node after 15 minutes in flight. Nevertheless, thanks to the federated approach among the systems, the ground station was still able to retrieve the balloon’s data in real time through the network system, for which the other balloon operated as a federated relay for 45 minutes in flight, uninterrupted. In other words, the federated approach to the system allowed triplicating the useful lifetime of the defective system, which would have not been possible to realize otherwise. Such anomaly coincidentally demonstrated the value of the federated approach to space systems design. The paper paves the way for future tests on space assets.
