Marpu","doi":"10.1109/JMASS.2024.3355754","DOIUrl":"https://doi.org/10.1109/JMASS.2024.3355754","url":null,"abstract":"Nanosatellites, in particular, CubeSats, suffer from limited power and communication capabilities, which creates data throughput (DT) limitations imposing challenges on developers in implementing high data generating payloads, such as the ones deployed in Earth observatory missions. The study presents a framework—variable power modulation (VPM)—that involves varying the transmitter’ s output power within the adjustable range, such that in the case of power availability, the transmission output power is increased accordingly. VPM allows optimal derivation of power for the transceiver, leading in an increase in the average pass duration, thereby providing higher DT. The implementation of VPM involves initiating communication with ground stations at lower elevation angles. However, this approach necessitates a thorough examination of the impact of small-scale fading, particularly Rician Fading, which can affect the signal reliability. In addition to VPM, the study also explores the integration of variable coding and modulation (VCM), a standard practice in communication systems. This article provides a comprehensive analysis of how VPM and VCM can collaborate to enhance the DT of CubeSats. Results from the study indicate that VPM can increase the DT of a standard 1U CubeSat by approximately 43%, while VCM alone can boost it by around 250%. When both VPM and VCM are combined, the DT experiences a remarkable improvement of approximately 340%. However, it is worth noting that the introduction of Rician Fading has a modest adverse effect, leading to a reduction in DT of up to 19%. It is important to highlight that while VPM does not necessitate complex or customized components for CubeSat adoption, it does require transceivers with in-flight configurability. Additionally, it is crucial to consider potential tradeoffs in link reliability when applying the proposed framework, as it can impact this aspect in certain scenarios.","PeriodicalId":100624,"journal":{"name":"IEEE Journal on Miniaturization for Air and Space Systems","volume":"5 2","pages":"85-93"},"PeriodicalIF":0.0,"publicationDate":"2024-01-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141091178","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Utilizing the multiresolution and scale-invariant properties of undecimated wavelets, our model separates low-frequency information component and three high-frequency information components from a low-resolution image. Our model achieves decorrelation of image pixel information and generates wavelet domain energy normalization features. Utilizing a fully connected neural network, we construct a wavelet-based image SR quality prediction network. This neural network combines four subnetworks to enhance the network representation and learning capabilities. The network is trained using wavelet domain energy normalization features, while autonomously learning the mapping relationship between input data and evaluation metric. This model is validated on infrared image data sets. The experimental results indicate that the proposed model can accurately predict SR image quality metrics by utilizing frequency-domain energy features of a low-resolution image.","PeriodicalId":100624,"journal":{"name":"IEEE Journal on Miniaturization for Air and Space Systems","volume":"5 2","pages":"79-84"},"PeriodicalIF":0.0,"publicationDate":"2024-01-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141091216","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on the obtained time-series data, the surface deformation pattern is extracted, the risk level of subsidence hazard is classified, and the spatial and temporal evolution patterns of typical areas are analyzed to further explore the causes of ground subsidence in the study area. The results show that the maximum subsidence rate in the main urban area of Nanjing from 2018 to 2023 reaches 23 mm/yr, and the cumulative subsidence reaches 50 mm. The total area of the subsidence high-risk zone is about 2.3 km2, which accounts for 0.4% of the total area of the main urban area, and the risk of ground subsidence is relatively low. A small part of the surface subsidence area is concentrated in the zone near the Yangtze River, which needs to be focused on. This article proved that the combination of the PS-InSAR method and subsidence risk assessment is effective for urban surface deformation monitoring, and the results of this article can provide a scientific and reliable basis for urban management.","PeriodicalId":100624,"journal":{"name":"IEEE Journal on Miniaturization for Air and Space Systems","volume":"5 2","pages":"73-78"},"PeriodicalIF":0.0,"publicationDate":"2024-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141091215","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Like many satellites, CubeSats also entails the integration of different subsystems for successful execution of the mission(s) requirements. Among these subsystems, onboard computer (OBC) is one of the integral parts of the CubeSat and its failure could result in the loss of the entire mission. This article presents a study guide to design any mission-specific OBC for CubeSats with considerations to make it reliable while assessing performance and power consumption. Reliability is addressed by electronic components selection, architectural design, and fault-tolerant techniques at both hardware and software levels. A performance enhancement methodology is also discussed by coherent selection of storage devices, interfaces, and the processing unit. Then, different hardware and software level techniques are discussed to reduce OBC power consumption. Finally, an OBC architectural design is proposed for the National CubeSat of Pakistan (ICUBE-N) while considering its reliability, low-power consumption, and enhanced performance.","PeriodicalId":100624,"journal":{"name":"IEEE Journal on Miniaturization for Air and Space Systems","volume":"5 2","pages":"59-72"},"PeriodicalIF":0.0,"publicationDate":"2023-12-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141091152","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
