1. 1. Conjugate Heat Transfer Analysis of HPGP Thruster

   University essay from Luleå tekniska universitet/Rymdteknik

   Author : Lisa Svensson; [2024]
   Keywords : aerospace; HPGP; ECAPS; ANSYS; conjugate heat transfer; thruster; space;

   Abstract : This master's thesis was conducted in collaboration with ECAPS, where a conjugate heat transfer analysis on their High Performance Green Propulsion (HPGP) 22N thruster was done. ECAPS is a Swedish propulsion company specializing in green propulsion. They develop thrusters for spacecraft orbit and attitude control, utilizing the propellant LMP-103S. READ MORE

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Therese Bäckström; [2023]
   Keywords : Electric Propulsion; Field Emission Electric Propulsion Testing; FEEP Testing; Thruster Testing; Heaterless Hollow Cathode Testing; HHCTesting; Cathode Testing; Anode Design; Anode Configuration; Electrical Interface; Elektrisk Framdrivning; Fältjonisationsframdrivningstestning; Framdrivningstestning; Värmelös Hålkatodstestning; Katodtestning; Anoddesign; Anodkonfiguration; Elektriskt Gränssnitt;

   Abstract : Electric Propulsion (EP) is widely acknowledged as a crucial technology for future space missions, offering significant propellant savings and enabling exploration of planetary missions with smaller spacecraft (s/c). For precise attitude control of these smaller spacecraft, Field Emission Electric Propulsion (FEEP) has emerged as a favorable option due to its exceptional thrust controllability. READ MORE

5. 4. Real Time Navigation Algorithms for LEO Small Satellites using COTS GNSS

   University essay from KTH/Lantmäteri – fastighetsvetenskap och geodesi

   Author : Nathan Groisne; [2023]
   Keywords : PNT; Small Satellite; COTS; GNSS; Navigation; ACS; PNT; små satelliter; COTS; GNSS; navigering; ACS;

   Abstract : Many satellites in LEO use a GNSS-based navigation system, taking advantage of the GNSS constellations in MEO to enhance navigation capabilities. The thesis work focused on developing the software enabling GNSS-based navigation for Hemeria's future small satellites operating in LEO. READ MORE

6. 5. Improving the guidance, navigation and control design of the KNATTE platform

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

   Author : Lars Lundström; [2023]
   Keywords : Multisensor Data Fusion; Nonlinear Kalman Filter; Neural Network;

   Abstract : For complex satellite missions that rely on agile and high-precision manoeuvres, the low-friction aspect of the space environment is a critical component in understanding the attitude control dynamics of the spacecraft. The Kinesthetic Node and Autonomous Table-Top Emulator (KNATTE) is a three-degree-of-freedom frictionless vehicle that serves as the foundation of a multipurpose platform for real-time spacecraft hardware-in-the-loop experiments, and allows emulation of these conditions in two dimensions with the purpose of validating various guidance, navigation, and control algorithms.
