PHASE 1 - Commissioning
As soon as ION SCV LUCAS reaches orbit, our spacecraft operations engineers establish a bidirectional communication channel. We then start the launch and early orbit phase (LEOP), neutralizing the rotation imparted by the launch vehicle during separation, correcting the attitude, testing the satellite’s subsystems, and preparing for the next phases.
PHASE 2 - Commercial Phase, Orbital Transportation
Once concluded the commissioning phase, ION SCV LUCAS starts the commercial phase of the mission with the deployment of satellites into a 500km sun-synchronous orbit. The deployment strategy, called fast dispersion, enables an even distribution along the operational orbit within a fraction of the time allowed by traditional dispersion techniques.
PHASE 3 - Commercial IOD
After completing the deployment, ION SCV LUCAS performs in-orbit demonstration and validation (IOD/IOV) of commercial payloads integrated within the platform, including a green propulsion system developed by a third-party company.
PHASE 4 - Educational Program
The Origin mission includes an educational program in collaboration with an “Istituto Statale di Istruzione Superiore" (ISIS) in the Lombardy Region and Aviosonic. The program enables high-level students – who have been involved in the development of an amatorial ground station– to establish a communication channel with the satellite through a UHF transceiver that works in satellite amateur radio band (435 – 438 MHz). Once connected, the students will be able to downlink telemetry and execute a number of educational operations through telecommands.
PHASE 5 - Internal Experiments
Before the official end of the mission, our engineers perform additional testing of subsystems, maneuvers, and procedures in preparation for the upcoming Pulse and Wild Ride missions.
PHASE 6 - Decommissioning
At the end of the mission, the spacecraft is decommissioned in compliance with the Space Debris Mitigation guidelines. The pressure vessels are depleted from leftover fuel and oxidizer, the battery charging system is deactivated, and the batteries are completely discharged. The spacecraft, now inert, enters a decommissioning trajectory that will bring it to burn up upon atmospheric re-entry within a few years.
