1. 1. Microsatellite Constellation for Wildfire Monitoring

   University essay from KTH/Geoinformatik

   Author : Citlali Bruce Rosete; [2022]
   Keywords : microsatellite; shortwave infrared sensor; active fire monitoring; burned area detection; satellite constellation; mikrosatellit; kortvågig infraröd sensor; aktiv brandövervakning; detektion av brandhärjat område; satellitkonstellation;

   Abstract : I flera års tid har antalet svåra och okontrollerade skogsbränder ökat i antal. Det finns ett behov av att detektera skogsbränder med hjälp av satelliter som har högre tidsupplösning samt högre geometrisk upplösning än de satelliter som är i bruk idag. READ MORE

3. 2. Conceptual Design of an Air-Launched Three-Staged Orbital Launch Vehicle

   University essay from KTH/Rymdteknik

   Author : Måns Rasmussen; [2021]
   Keywords : Air-launched; Launch Vehicle; Three-staged; Rocket; Sun-Synchronous orbit; Solid propellant; Liquid propellant; Trajectory optimization; Nonlinear programming; JAS 39 Gripen; Fighter aircraft; Luftlanserad; Trestegsraket; Solsynkron bana; Fast bränsle; Flytande bränsle; Bananalys; Icke-linjär optimering; JAS 39 Gripen; Jaktflygplan;

   Abstract : The objective of this study was to design a launch vehicle capable of deploying a nanosatellite into a Sun-synchronous orbit at 500 km orbital altitude from the JAS 39E/F Gripen fighter aircraft. This was achieved by first performing theoretical calculations for the required nozzles and solid propellant grain configurations for the first two solid stages, followed by the necessary liquid propellant configuration for the third stage.

4. 3. The I2T5 : Enhancement of the Thermal Design of an Iodine Cold Gas Thruster

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : Roger Michael Pereira; [2020]
   Keywords : Cold gas thruster; I2T5; CubeSat propulsion; thermal analysis; heat transfer; thermal resistance; orbital heat fluxes;

   Abstract : The I2T5, an iodine-propelled, cold gas thruster, developed by ThrustMe, France, is the first of its kind to make it successfully to space. Due to its simple, reliable and cost-effective design, it is a suitable propulsion system for CubeSat missions with low delta-V (ΔV) requirements. READ MORE

5. 4. Robust and Agile Attitude Control for Triple CubeSat Eye-Sat

   University essay from KTH/Rymdteknik

   Author : Benjamin Charbaut; [2018]
   Keywords : ;

   Abstract : Eye-Sat is a student-designed 3U-CubeSat, to be launched to a sun-synchronous orbit from where it will map the zodiacal light, a faint glare caused by the reflection of Sun on interplanetary dust. Such mission requires an accurate 3-axis attitude control, for which Eye-Sat is equipped with reactions wheels, magnetorquers, magnetometers and a star tracker. READ MORE

6. 5. Thermal Control Design and Simulation of a Space Mission

   University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

   Author : Vincent Still; [2018]
   Keywords : ;

   Abstract : The following document describes an example mission, which originated from a real life concept of an imaging satellite in a Sun Synchronous Orbit (SSO)around Earth. This report takes the reader through the thermal analysis and evaluation of space equipment performed with Airbus Space & Defence’s Systema/Thermica tool, at Space Structures GmbH. READ MORE
