Special Issue Information

Dear Colleagues,

The miniaturization of spacecraft and in-orbit technologies is leading to a broader usage of small satellite platforms for technology demonstration, scientific experiments, and New Space businesses in the Earth's orbit. Given the number and the significance of the small satellite market and the exploitation of such platforms for scientific purposes, we propose the Aerospace Special Issue on “Small Satellite Missions”.

This aims to bring together cutting-edge research on the development of novel technologies, experiments, and methodologies for the development, assurance, and operations of small satellites. We encourage submissions that explore a wide range of innovative techniques and technologies, including but not limited to:

  • Small satellite (mini-, micro-, nano-, and pico-satellite) missions design and development.
  • Miniaturization of technologies for implementation in small satellites.
  • Assembly, Integration and Verification (AIV) approaches to small satellite missions and constellations.
  • Constellation and swarms design and operations.
  • Distributed ground segment networks for small satellite missions.
  • Innovative approaches to system engineering applied to small satellite missions.
  • Subsystems development and operations for small satellite missions and operators.
  • New mission profiles (MEO, HEO, Near-Earth, Lunar, Deep Space, Planetary) for small satellite missions.
  • Trajectory design and navigation systems.
  • Small satellites tracking and space traffic management.

Authors are encouraged to present original research articles that provide a comprehensive overview of the state-of-the-art in this rapidly evolving field.

This article focuses on the development of a 3D-printed 2-degree-of-freedom (DOF) joint for the payloads’ orientation on small satellites. This system is a compliant mechanism, meaning that this monolithic system composed of cross-axis flexural pivots (CAFPs) produces complex movements through the elastic deformation of its structure. Using fused filament fabrication (FFF), a demonstrator made of Polyetherketoneketone (PEKK) is printed to determine its potential compatibility with space conditions. Focusing on a segment of the joint, the CAFP, this study aims for an enhancement of its mechanical behavior through the study of its printing direction and the creation of an accurate finite element model of this compliant mechanism. First, material characterization of 3D-printed PEKK is achieved through differential scanning calorimetry tests of the filament and flexural and tensile tests of specimens printed in different printing directions. Then, these data are used to perform a finite element analysis of different CAFP designs and compare their mechanical response of their 3D-printed twin using digital image correlation software. Finally, the CAFP structures were observed by X-ray tomography. The results show that printing direction greatly influences both flexural and tensile strength. Voids induced by the FFF process could impact the mechanical behavior of 3D-printed parts as the simple CAFP design has a better test/model correlation than complex ones. This could influence its resistance to space environment. Full article

The atmospheric total water vapor content (TWVC) affects climate change, weather patterns, and radio signal propagation. Recent techniques such as global navigation satellite systems (GNSS) are used to measure TWVC but with either compromised accuracy, temporal resolution, or spatial coverage. This study demonstrates the feasibility of predicting, mapping, and measuring TWVC using spread spectrum (SS) radio signals and software-defined radio (SDR) technology on low Earth-orbiting (LEO) satellites. An intersatellite link (ISL) communication network from a constellation of small satellites is proposed to achieve three-dimensional (3D) mapping of TWVC. However, the calculation of TWVC from satellites in LEO contains contribution from the ionospheric total electron content (TEC). The TWVC and TEC contribution are determined based on the signal propagation time delay and the satellites’ positions in orbit. Since TEC is frequency dependent unlike TWVC, frequency reconfiguration algorithms have been implemented to distinguish TWVC. The novel aspects of this research are the implementation of time stamps to deduce time delay, the unique derivation of TWVC from a constellation setup, the use of algorithms to remotely tune frequencies in real time, and ISL demonstration using SDRs. This mission could contribute to atmospheric science, and the measurements could be incorporated into the global atmospheric databases for climate and weather prediction models. Full article
