Angular Properties of Ionic Liquid Electrospray Emitters
(American Institute of Aeronautics and Astronautics, 2023-01)
The angular distribution of emitted species in electrospray ion beams is not well characterized and can have negative effects on propulsive performance and emitter lifetime. We present an experimental characterization of ...
Ultra-Long Baseline Time-of-Flight Mass Spectrometry with the AMIGAS Multi-Spacecraft Concept
(Institute of Electrical and Electronics Engineers, 2023-03)
Time-of-flight mass spectrometry allows for the study of elemental, isotopic, and molecular composition from a material sample. The mass sensitivity and resolution of time-of-flight mass spectrometers increases with the ...
A Method for Direct In-Space Thrust Estimation from Low-Acceleration Orbital Maneuvers
(2023-06)
This paper presents a method for performing direct in-space thrust estimation for low-acceleration propulsion systems using measurements of the spacecraft's position taken during an orbital maneuver. The method is based ...
Segmented Reconstruction of Low-Acceleration Orbital Maneuvers
(American Institute of Aeronautics and Astronautics, 2023-08)
This paper considers the problem of inferring the acceleration acting on a spacecraft in a near-circular orbit around a large planetary body when the acceleration is known to act in the along-track direction. A segmented ...
