  6. IMPACT ON GROUND ACTIVITIES

  7. GENERAL PROBLEM International community unanimously declares that solutions shall be found to mitigate the problem Satellite infrastructure and related space operations are critical for the world economy. Spy satellites, telecommunications, weather forecasting, remote sensing satellites, etc. all have a key role on the global security and on current quality of life (source: Le Scienze, June 2014) Today it is not clear if risks and costs derived by collisions justify the investments on solutions to remove already existing debris and defunct satellites (ADR missions*) or if it would be enough to stop creating new debris (*) Active Debris Removal missions are currently under study in Europe and US. Delivery estimation is in at least ten years from now. Cost estimation is about billions per mission

  8. GENERAL PROBLEM It is commonly accepted by the whole international community that the best current approach is to adopt solutions that prevent the creation of new space debris (prevent better than heal) International guidelines and national regulations are now in place and are currently becoming more strict and severe

  9. GENERAL PROBLEM Exploitable orbits are gettingcrowded with satellites and debris Satellite operators pain (*) Collision risk Number of debris growing Revenues reduction for operators High risk of losing orbital space in the future Huge and critical impact on human society (*) not only for satellite operators

  11. D-SAT Mission & Sat-Alert Experiment

  12. D-SAT Mission • The D-SATsatellite is aThree Unit cubesat platform designed, build and integrated by D-Orbit. • The D-SATsatellite carries out two innovative experiments: • the SatAlert experiment that will be performed during the D-SAT mission; • the first and uniquedemonstration of an independent, quick and safe satellite decommisioning.

  13. Decommissioning Demonstration FIRST SATELLITE TO BE REMOVED IN A QUICK, SAFE AND CONTROLLED WAY D-ORBIT Decommissioning Device fully qualified for space applications

  14. D-SAT Configuration(1/2) D-SAT is composed by three main elements: • the Platform, a complete standard cubesatsystem; • the Decommissioning Device, with an independent electric power system, on-board computer and attitude determination and control system; • the Decommissioning Motor, to provide the propulsive thrust for the deorbiting maneuver.

  15. D-SAT Configuration(2/2) • Satellite • Mass: 4000 g • Dimension: 340 x 100 x 100 mm • Power System: • AverageInput Power in orbit: 4.25 W* • Maximum Input Power: 9.6 W* • 2 Battery Pack with 21Whr capacity, integratedon ElectricPower System • Communication System: • 2 independent Communication System that provide Half duplex communication • omnidirectional turnstile antenna • Transceiver: • Frequency: 437.505 MHz • Morse Beacon FM Modulated • Tele-command and Telemetry digital data • Baud rate 4800 bps • GMSK signal FM • Satellite Transmitted Power = 1 W * calculated for a 450 km circular equatorial orbit (Orbit period ≈ 93)

  16. D-SAT Integration Progress

  17. D-SAT Mission Analysis (1/2) • Deployed from Nanorack (Internation Space Station) • Expected Launch Date: Last quarter 2015 • Mission Lifetime (2 months) • Operative Mission Center: • Main Ground Station at Lomazzo (CO) • Secondary Ground Station at Firenze • Communication Session: • Visibility windows per day: 3 or 4 • Visibility period: 480s

  18. D-SAT Mission Analysis (2/2) • Decommissioning Maneuver • Impact location in uninhabited regions, in open sea (Arabian Sea) • Reentry Time 20 min

  19. SatAlert Experiment Objectives SatAlert experiment consists of a short MAMES message transmission over a LEO-satellite. Objectives: • To prove the applicability of direct LEO satellite reception of MAMES messages. • To validate the MAMES transport enhancers (reception robustness improvements). • To evaluate the on-board processing load on ARM-based host processor for the capture, processing and relaying of MAMES alert envelopes. • To provide a demonstrated proof-of-concept of low-cost on-demand satellite alerting system.

  20. SatAlert Experiment Details • Earth-to-Satellite path • Satellite-to-Earth path • During the visibility period the Earth station sends to the satellite a MAMES message (maximum width of 4KB). • The MAMES Message will be stored in the satellite On-Board Computer memory. • As a trigger command is sent by the Earth Station (NOC), the MAMESmessage stored on satellite will be broadcasted (on-demand transmission). • MAMES broadcast transmission will be actived in all the available visibility windows. • Two dedicated Earth Stations will be implemented for the reception and de-encapsulation of the MAMES messages. Satellite TX Earth Station - NOC- (uplink) Dedicated RX Satellite Earth Stations

  21. ITALIAN GLOBAL IMPACT EMERGENCY AND CRITICAL SCENARIOS SPACE DEBRIS MITIGATION AND PREVENTION NANOSATELLITES AS THE NEXT SATELLITE INDUSTRY • Warn population to avoid critical scenarios and lives losses • Connect in real time institutions, national security and doctors to help containing diseases spreading (i.e. current project for Ebola) • Possibility to aid Search and Rescue operations in helping rescue teams retrieving missing people • Stop the increasing concentration of defunct object in Space • Reduce the risk of collision with people and critical asset on Earth • Reduce costs of access to space • Improve reliability of Earth Observation satellites • First step for a sustainable space • Exponential growth: 300% growth in three years, 2000 nanosatellites expected to be launched in the next 2 years • Less material wasted, less cost for launch, less cost for services

  22. OUR RESPONSIBILITY Every profitable choice should be sustainable. Every responsibility should take care of who we care most.
