Debris Collision Alert System

DeCAS mission

During the DeCAS in-orbit test validation, alert messages forecasting the D-SAT simulated re-entry footprint position will be encapsulated in MAMES protocol, making it one of the MAMES emergency messages stored in D-SAT for re-broadcast. Aviosonic has established a ground station at Andrea Ponti Institute in Gallarate Center to validate all of the DeCAS communications and the three-segment DeCAS system - specifically space, ground and user.

DeCAS

D-SAT validates this approach by simulating the use of DeCAS during the orbital phase, performing an actual test during re-entry. This helps develop our technology which will greatly improve re-entry safety for the next generation of space vehicles.

END OF THE MISSION

September 14th, 2017: Aviosonic Space Tech, D-Orbit and CNIT announce the successful completion of the orbital segment of the D-Sat mission. Launched on June 23rd, D-Sat completed an eleven-week flight plan, during which it performed multiple iterations of DeCas and SatAlert experiments.

This exciting result was made possible by an outstanding collaboration between Aviosonic Space Tech D-Orbit and CNIT.

To validate the system, D-Sat’s ground operators have submitted 83 messages simulating uncontrolled re-entry. DeCAS was able to process more than 98% of these in real-time and afterwards it sent them to CNIT for the encapsulation into MAMES protocol messages and for the consecutive upload. Ten of these alerts have successfully completed the entire process, simulating a DeCAS satellite broadcast service. Thanks to a collaboration with Ponti Institute and ARI of Gallarate, where Aviosonic had installed its ground station, all DeCAS messages have been received, along with more than 14 hours of D-Sat broadcasts, validating the whole system architecture.
