    PW-SAT – What is it and how we made it PW-SAT – What is it and how we made it Presentation Transcript

    • PW-SAT – What is it and how we made it Maciej Urbanowicz Students Space Association, Warsaw University of Technology TS2 Satellite Technologies
    • PW-Sat – the beginningAt the Warsaw University of Technology➔The beginning: 2004, 2005 (mission statement)➔Students Space Association(Faculty of Power and Aeronautical Engineering)➔Student Space Engineering Scientific Group(Faculty of Electronics and Information Technology)
    • PW-Sat – the beginningAt the Warsaw University of TechnologyWhy should we build a satellite?➔➔ Increase prestige and reputation (the 1 st satellite!)➔ Enhance education and technical knowledge➔ Build space capabilities and sustainability➔ Space promotion and advocacy (Poland is joining ESA as a full state member!)
    • PW-Sat – mission statementObjectivesPW-Sat as...➔… educational project➔… technology demonstratorMission statement:To educate students at spacecraft development and Credits: Maciej Urbanowiczspace project management to demonstrate the newtype of a de-orbitation system in the CubeSat projectas a technology demonstrator for the small satellitemission.Objectives:➔To test a technology developed by POLES!➔De-orbit the satellite Credits: Maciej Urbanowicz
    • PW-Sat – mission statementMission(s) definition(s)The motivation:➔PW-Sat selected by the EducationOffice of the ESA as a payload to theVega Maiden Flight! Credits: ESA Credits: ESA
    • PW-Sat – mission statementMission(s) definition(s)Concept➔Increase a cross section:balloon → sail → tailStrategy: 3Bs Credits: PW-Sat➔B (Build)➔B&B (Build & Buy) Credits: P. Sańczyk➔B (Buy) Credits: M. Urbanowicz
    • PW-Sat – designMission schedule and level of success (1):➔ 1. The satellite successfully passed all of the tests. It has been approved toflight by the ESA.➔2. The satellite was integrated with other CubeSats in the P-POD and preparedto the flight. The satellite was integrated with the launch vehicle.➔3. The satellite was launched to space.➔4. The antennas were released and the transceiver started working in the basicmode. All subsystems are in a good condition.➔5. The satellite is fully operational, downlink and uplink* transmission workproperly. It is possible to operate the satellite.➔6. The tail was deployed. The deorbitation phase has been started.➔7. The satellite has been deorbited.➔* - Currently (26th September 2012) the PW-Sat has reached 4 th level andparticularly 5th.
    • PW-Sat – designMission schedule and level of success (2): Phase name Time Purpose Commissioning T+0 – T+ 30 min. Satellite separation. Separation switches turn on satellite. The OBC starts counting down T30 min. Antenna deployment T+30 min Deployment of antenna system. The satellite starts send telemetry and receive signals from ground station. Operational phase 1 T+30 min Satellite sends telemetry, receives data. Normal operational phase is performed. Operational phase 2 T+1 month The tail is deployed from the payload container. Deorbiting phase is started. AP&P gathers tails parameters. Telemetry is sent to ground station. Deorbiting T – (~1 year) Satellite is being deorbited.
