The basic element of the satellite subsystem is the on-board computer, which usually consists of standard elements such as: processor, memory, dedicated FPGAs and input/output interfaces. The on-board computer is responsible for executing the software that accomplishes the mission's objectives. In accordance with the ESA requirements, the software consists of at least two layers: boot and application software.

On-board systems are on the verge making use of state-of-the art multi-core processors and FPGA technologies that encompass multiple functional blocks and features. The investigations on how to exploit such technologies was started in the three-ways TRP activities (T701-504ED, T702-502SW, T705-504EC) under the umbrella of Compact Reconfigurable Avionics. In such systems, the Software running on multiple-cores can be tightly coupled to functions implemented in the reconfigurable FPGA.

SIDLOC (Spacecraft Identification and Localization) is a new transmission scheme proposed by Libre Space Foundation to enable LEO satellite identification and tracking. The SIDLOC system relies on a reduced size autonomous transmitter that requires minimal integration and area on the carrier spacecraft. The ground segment of the SIDLOC system utilizes the existing SatNOGS network and the UHF band to perform the signal demodulation and identification. The SIDLOC system uses DSSS (Direct Sequence Spread Spectrum) PSK modulated signals with an effective bitrate of ~50 bits/s.

The main objective of the activity was to evaluate the usage of Rust programming language in space applications, by providing an RTOS targeting ARM Cortex-M7 SAMV71 microcontroller, a BSP (Board Support Package) and a Demonstration Application. RTOS is implemented in the form of an executor instead of a classic scheduler. The scope of this project doesn’t include preemption. This executor runs tasklets, which are fine-grained units of computation, that execute a processing step in a finite amount of time.

A critical function on board all spacecraft is the Failure Detection, Isolation and Recovery (FDIR) subsystem, which is vital in ensuring the safety, autonomy and availability of the system. Modern satellites complexity is increasing, and these highly complex systems require bespoke FDIR solutions with complicated architectures and difficult testability.

LIDAR for GNC developments in the past years, targeting rendez-vous applications, have proven to be a very successful product in the world market. This LIDAR can also be adapted for other scenarios and in particular for landing applications. There is quite a high demand for this type of product which is not available yet on the market.
