Among others it provides a method to estimate the communication link capacity requirement for future ATM services. Nevertheless, the COCR document is written as a general guideline, without taking into account any technological implementation.<\/jats:p>\n          <jats:p>In this work we present a methodology to estimate the capacity in terms of communication bit rate requirements for ATM services in a constellation of geostationary (GEO) satellites with spot beams. The complete approach is illustrated using concrete scenario elements and assumptions as well as numerical parameter values along the whole process.<\/jats:p>\n          <jats:p>The bit rate requirement per spot beam is determined using a similar approach to the one in the COCR, with some parameters adjusted to fit in a satellite system scenario. Furthermore, the criticality of one particular service message, the A-EXEC, is verified by comparing the required bit rate when it is excluded from the computation. A condition when this criticality applies is also determined.<\/jats:p>\n          <jats:p>The result of this work may thus contribute to the assessment of appropriate technologies used for ATM in the Future Communications Study (FCS) framework [EUROCONTROL\/FAA, Technical report].<\/jats:p>","DOI":"10.3233\/sc-2008-0342","type":"journal-article","created":{"date-parts":[[2019,12,3]],"date-time":"2019-12-03T16:15:17Z","timestamp":1575389717000},"page":"123-141","source":"Crossref","is-referenced-by-count":0,"title":["Capacity dimensioning for Air Traffic Management (ATM) services in a GEO satellite system with spot beams"],"prefix":"10.3233","volume":"21","author":[{"given":"Eriza Hafid","family":"Fazli","sequence":"first","affiliation":[{"name":"TriaGnoSys GmbH, Argelsrieder Feld 22, D-82234 Wessling, Germany.
