Design of Onboard Avionics Based on Commercial Off-the-Shelf Parts for TianQi-2 Nanosatellite J. Spacecr. Rockets (IF 1.6) Pub Date : 2024-04-05 Lianxiang Jiang, Wang Lei, Li Mingxiang, Zhang Teng, Xu Peipei
With the development of modern small satellite technology, short development cycles, low cost, and high reliability have become trends in the era of New Space. To achieve the above goals, an integrated centralized architecture of onboard avionics for an internet of things CubeSat was proposed, and CAN, I2C, and 1-wire buses were employed for telemetry collection and command sending. The implementation

Thermospheric Density Estimation Method Using a First-Order Gauss–Markov Process J. Spacecr. Rockets (IF 1.6) Pub Date : 2024-04-03 Jinyuan Li, Hong-Xin Shen, Pu Huang, Yin Chu, Hexi Baoyin
Low-Earth-orbit (LEO) spacecraft are significantly influenced by atmospheric drag. Accurately estimating thermospheric density is pivotal for the precise calculation of drag acceleration. However, thermospheric density along a specific orbit, computed using existing thermospheric models, has certain inaccuracies. In this work, a first-order Gauss–Markov process is used to model the deviation of atmospheric

Orbital Facility Location Problem for Satellite Constellation Servicing Depots J. Spacecr. Rockets (IF 1.6) Pub Date : 2024-03-25 Yuri Shimane, Nicholas Gollins, Koki Ho
This work proposes an adaptation of the facility location problem for the optimal placement of on-orbit servicing depots for satellite constellations in high-altitude orbit. The high-altitude regime, such as medium Earth orbit, is a unique dynamic environment where low-thrust propulsion systems can provide the necessary thrust to conduct plane-change maneuvers between the various orbital planes of

Low-Thrust Resonance Gravity-Assist Trajectory Design for Lunar Missions J. Spacecr. Rockets (IF 1.6) Pub Date : 2024-03-23 Jinsung Lee, Jaemyung Ahn
This paper introduces a procedure to optimize a low-thrust gravity-assist trajectory to the Earth–moon L1 periodic orbit utilizing the resonance-orbital structure as a guideline. The Earth–moon circular restricted three-body problem formulation is used to describe the problem. The proposed procedure determines the gravity-assist geometry and then finds the gravity-assist linking based on the multiple-point

Neural Network-Based Formation Flying Using Aerodynamic Forces via Variable Shape Function J. Spacecr. Rockets (IF 1.6) Pub Date : 2024-03-19 Shogo Kitamura, Saburo Matunaga
Conventional formation flying Earth-orbiting satellites control their orbits to perform their missions using thrusters, but the amount of propellant loaded into a satellite is limited. Therefore, the use of aerodynamic forces for orbit control has been attracting attention, particularly in low Earth orbit. The orbit control can be achieved by appropriately changing the state of satellite, such as attitude
