Rain attenuation is considered to be the dominant fading mechanism at this frequency range. The acceptable intersystem interference probability AIIP of the carrier-to-interference ratio CIR of a terrestrial station interfered by a satellite is defined and analytically calculated. Adaptive power control schemes are assumed to operate for both networks. The correlated propagation fading phenomena over multiple terrestrial and slant paths are accurately incorporated. The proposed model is physical and can be applied on a global scale since incorporates properly the local climatic conditions concerning the point rainfall rate and the spatial rainfall inhomogeneity. Useful numerical results of the present model are finally provided and the impact of various crucial operational and geometrical parameters of satellite and fixed wireless networks' coexistence is also examined.","PeriodicalId":51158,"journal":{"name":"Space Communications","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89641648","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 crucial aspect is the capability to accurately retrieve the tropospheric path delay along the line-of-sight of the deep space probe in order to allow precise tropospheric calibration of deep space observables range and range-rate with particular reference to the BepiColombo spacecraft and its primary DSA at Cebreros ES. The study focuses on two main aspects which lead to the preliminary design of the Mercury Orbiter Radioscience Experiment MORE MCS: the characterization of current microwave radiometers MWRs available at ESA/ESTEC and the atmospheric fluctuation effects on the MCS error budget, in terms of the Allan standard deviation ASD. In the course of the study, further critical aspects have been identified effects of Sun contamination, effects of ground noise emission, and mitigation strategies have been proposed. The final outcome is a preliminary design of the MWR and the entire MCS to be deployed at the ESA/ESTRACK ESA Tracking station network sites and being compliant with MORE requirements.","PeriodicalId":51158,"journal":{"name":"Space Communications","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90930371","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}

Cronin","doi":"10.3233/SC-130006","DOIUrl":"https://doi.org/10.3233/SC-130006","url":null,"abstract":"This paper reports on satellite beacon measurements at 12.7 GHz from late October 2010 until the end of June 2012 at two geographically separated Arqiva Teleport sites in Southern England in order to obtain propagation data to be used in operational decision making and improvement of the scientific understanding of such effects. These sites operate at very low elevation angles 4.1 and 5.3 degrees and therefore experience significant propagation effects. Measurements are on-going to achieve meaningful long term statistics, however there is value in comparing the results obtained at both sites over the common period of measurement data to date approximately 20 months. The measurements are performed at 1/2 second intervals and statistical analysis applied. A primary objective of this work is to assess the influence of tropospheric scintillation and consequently the paper will focus on this with the addition of some lesser material on rain fade effects. The measurements and analysis have been performed as a collaborative effort between Arqiva and staff who work at the University of Surrey. It is emphasised that the primary objective of this work is to assess the influence of tropospheric scintillation and rain attenuation from an operational perspective and to a lesser extent from an academic viewpoint.","PeriodicalId":51158,"journal":{"name":"Space Communications","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2013-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79735372","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}
