# Brainstorm Smallsat

## Stipendium: 
- ~~DAAD: https://www2.daad.de/ausland/studieren/stipendium/de/70-stipendien-finden-und-bewerben/?status=&target=&subjectGrps=&intention=&daad=&q=kongress&page=1&detail=57479681~~
- Student Travel Award: 16th of May 

## Ideas/Topics
- Mission proposal
- Specific topic, such as actuator
- overlapping topic where everyone can contribute from their perspective
- exhibit move (350$)
- Topic related to SS23 theme
    - MOVE constellation for Space Debris? "Scaling the MOVE-III satellite concept to a constellation for Space Debris Awareness and Modelling"
        - costs?
        - coverage?
        - does it bring more knowledge?
        - adaptations of the satellite necessary?
        - Constellation operations concept?

## To-Do:
- Contact PhD's/Reviewers until 17th of January:
    - David Messmann (Johannes)
    - Xanthi (Natia)
    - Martin Langer (Lucien)
- Preliminary results until 17th of January:
    - Cost (Lucien)
        - Literature Research
        - MOVE interviews (Felix (?): money spent, DLR grants etc
        - MOVE-II people
    - Coverage (Johannes)
        - statistic research
        - number of satellites necessary
        - orbit

## Johannes
* IDEA: older space dust constellation with statistical verification of MASTER: https://conference.sdo.esoc.esa.int/proceedings/sdc6/paper/70/SDC6-paper70.pdf
* Maybe we can proof this? https://arc.aiaa.org/doi/10.2514/1.A34269
  > Thus, a flux of micrometer-size space debris is thought to be relatively lower in the region where the declination is approximately +-60 deg. 
* Space dust (clouds) is believed / modeled to be distributed by a Poisson likelihood
* Constellation options: 
    * polar (100% coverage, highest coverage close to poles)
    * walker with lower inclination + one sat in polar orbit
    * Combination of many different inclinations and heights for great and equal coverage --> much more expensive to launch
* Is the direction of orbit / inclination (0-90 / 91-180) of importance?
* 5 year deobrit rule (after mission completion) https://www.fcc.gov/document/fcc-adopts-new-5-year-rule-deorbiting-satellites

## Meeting with David
* Gegenüberstellung von move iii mit konstellation
* mögliche verbesserungen: coverage, vergleich mit move iii design (ADLER, IDEA)
* talk with science-> was wollen die (ursprüngliches MOVE-III Ziel genau untersuchen)
* kostenvoranschlag an pns lehrstuhl als basis für uns
* ausgangsbedingungen klar machen
* requirements die fix sind (Ausgangsbedingungen, Kosten, Fragestellung, …)
* was wollen wir untersuchen
* fragestellung die man beantworten kann
* keine ergebnisse versprechen, eher offen halten
* herausarbeiten wieso wir das machen haha
* verschiedene orbits mit gradialler abdenkung, 3d modell von space debris
* drama und master verwenden um modelle/vermutungen zu bestätigen
* abstract zum probelesen abgeben
