Small-scale magNetosphere and Ionosphere Plasma Experiment (SNIPE) mission is aimed to observe a small-scale structure of the physical phenomena in near-Earth environment. SNIPE comprises four 6U size nanosats that perform formation flying meet scientific objectives mission. In this study, we designed system validated it using numerical simulations collect temporal spatial differences for The requirements spacecraft are pass same point at different times be located longitude points on...
This paper presents the systems of CANYVAL-C mission—a mission that demonstrates concept a virtual space telescope for solar science mission, which is achieved by using two CubeSats (1U: Timon, 2U: Pumbaa). The aim to capture images corona performing precise formation flying. Two CubeSat were developed this investigation: 1U and 2U CubeSat. can take several pictures corona, whereas blocks sunlight with its payload, called Occulter. To accomplish goal guidance, navigation, control...
This study designs a multistatic synthetic aperture radar (SAR) formation-flying system for very-high-resolution stripmap imaging (VHRSI) using manufacturable SAR microsatellites. Multistatic formation specifications VHRSI are derived based on the image theory. For simultaneous multi-satellite operation, advantages of autonomous orbit and attitude control prominent in terms workload ground station or efficient performance missions. Therefore, relative-orbit-control algorithm relative orbital...
In a launch environment, all satellites are subjected to severe random vibration and acoustic loads owing rocket separation, airflow, injection/combustion of the fuel. Structural vibrations induced by mechanical cause malfunction vibration-sensitive components in satellite, leading failures during process or an on-orbit mission. Therefore, this study, shape memory alloy-based isolator was used on connection between vehicle satellite reduce transmission satellite. The exhibited high...
This study designs and analyzes satellite formation flying concepts for the Small scale magNetospheric Ionospheric Plasma Experiments (SNIPE) mission, that will observe near-Earth space environment using four nanosats. To meet requirements to achieve scientific objectives of SNIPE three are analyzed: a crossshape formation, square-shape cross-track formation. Of scenarios, crosstrack scenario is selected as final mission. The result this suggests relative orbit control maintenance...
This paper presents the operational scenario of CANYVAL-X (Cubesat Astronomy by NASA and Yonsei using Virtual telescope ALignment eXperiment) mission along with resulting lessons learned from early operation.The objective this demonstration is to verify a vision alignment system two CubeSats in low Earth orbit.The were launched on 12 January 2018 at Sriharikota launch site PSLV-C40.CubeSat team designed developed automatic communication programs manage normal CubeSat operation.After 43 days...
This paper suggests a relative orbit control strategy for the CubeSat Astronomy by NASA and Yonsei using Virtual Telescope Alignment eXperiment (CANYVAL-X) mission whose main goal is to demonstrate an essential technique, which arrangement among two satellites specific celestial object, referred as inertial alignment, next-generation virtual space telescope. The alignment system has requirements state. Through proposed strategy, consisting of separation, proximity keeping, reconfiguration,...
For the low-cost improvement of laser communication, which is critical for various applications such as surveillance systems, a study was conducted on relative distance control based orbital drift rate modulations multiple CubeSats during formation flying. The VISION mission covered in this paper comprises two to demonstrate communication technology space. During mission, deputy CubeSat changes execute objectives within scenarios. Impulsive controls decrease, maintain, and increase between...
