In this context, delay-tolerant networking (DTN) protocols are a native fit for data transfer. Unfortunately, the state of the art in the DTN domain is incomplete to fulfill this role. A Ring Road deployment would for example heavily benefit from an approach to dynamically integrate ground stations into the overall network. In this paper, we present a novel concept applicable on LEO satellites to dynamically discover ground stations and predict future contacts to them. The approach does not only enable dynamic integration of constantly active ground stations, but as well of intermittently available ones. The predicted contacts are intended to be leveraged by a DTN routing algorithm, e.g. a modified variant of Contact Graph Routing (CGR). The approach has been designed for low-cost LEO satellites with low hardware resources such as CubeSats. Finally, focusing upon microcontroller-based execution environments, we have intensively evaluated our results within realistic test cases based on an existing DTN protocol implementation.","PeriodicalId":177862,"journal":{"name":"2016 IEEE International Conference on Wireless for Space and Extreme Environments (WiSEE)","volume":"119 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116024430","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}

Especially for long distances between the observer and the environment, required data volume for transmitting a parametric description of the spatial distribution becomes critical. Simple physical models or assumption of parametric base functions do not provide sufficient prediction accuracy. Statistically based methods for field reconstruction such as Kriging or Gaussian Process Regression provide good accuracy, even if the measurements are overlaid with noise, provided all sensor data is transmitted. The new method presented in this paper calculates a small set of quasi optimal virtual sensor positions located in-between the real sensors. By transmitting only the predicted values of these virtual sensors, the spatial field can be reconstructed with less transmitted data and without significantly increasing the prediction error. The new approach was verified in a simulation scenario for a temperature field caused by diffusion and advection phenomena, which yielded a data compression by a factor of up to four. For large variations of the number of sensors and of the magnitude of measurement noise, the prediction error was always lower compared with the parametric base function models.","PeriodicalId":177862,"journal":{"name":"2016 IEEE International Conference on Wireless for Space and Extreme Environments (WiSEE)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123948847","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}

To enable interoperability within this satellite network particularly for autanomous operations and provide on-orbit data handling through distributed processing, a reliable inter-satellite communication (ISC) is required. In this paper, we examine the suitability of Light-Emitting Diodes (LEDs) for ISC in multi-satellite networks, and further propose an approach of the physical layer design that meets the requirements of the platform in terms of the size, weight and power (SWaP) of the satellite. An analytical model of the ISL is developed to test feasibility of using LEDs for reliable data communication in the presence of steady solar background illumination. Finally, the performance of the ISL is evaluated in terms of the Bit Error Rate (BER) and achievable data rates for four different intensity modulation and direct detection (IM/DD) schemes.","PeriodicalId":177862,"journal":{"name":"2016 IEEE International Conference on Wireless for Space and Extreme Environments (WiSEE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130261460","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}

At the sensor, optical power in form of monochromatic laser light is converted to electricity by photovoltaic laser power converters. These photovoltaic cells are optimized for the monochromatic wavelength of the light — opposed to solar cells, where the cell is optimized for efficeint conversion of the entire solar spectrum. By fine-tuning the absorber material's bandgap to the photon energy thermalization losses can be minimized. Consequently, highest photovoltaic conversion efficiencies of up to 60 % can be achieved. One advantage of optical power transmission is the possibility to combine the power supply with optical communication in a single channel. There exist different ways to realize such combination. One interesting idea is the concept of combined transceiver devices for both optical power reception as well as data reception and transmission. This work gives an overview of latest achievements in the development of photovoltaic laser power converters, including results from various absorber materials for different wavelengths, cell architectures with increased output voltages, and combined power and data transceiver device architectures.","PeriodicalId":177862,"journal":{"name":"2016 IEEE International Conference on Wireless for Space and Extreme Environments (WiSEE)","volume":"108 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115075003","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}

The fast development of power grid urgently requires reliable, efficient, and broadband wireless communication techniques for monitoring, protection, and control. High-voltage equipment and power-line, however, generate strong electro-magnetic (EM) field in its neighboring area. In this harsh environment, the performance of traditional radio-frequency (RF) wireless methods is significantly degraded, if not impossible. The authors developed an OWC system for this environment, which is able to satisfactorily solve the problem. Being different from the RF solutions, it uses light as the wireless information carrier to effectively resist electromagnetic interference (EMI). In order to further adapt this technique to the high-voltage situation, the authors developed and attached special isolation and self-powered supply modules to conventional OWC designs. The system was compared with a fiber system in the EM field of a 3kV converter. The results show OWC is able to provide satisfactory performance similar to a fiber system. In addition, it has exclusive advantages of being wireless, such as mobility, scalability and installation flexibility.","PeriodicalId":177862,"journal":{"name":"2016 IEEE International Conference on Wireless for Space and Extreme Environments (WiSEE)","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132777072","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}
