  3. Abstract:
  4. Satellite-based navigation has rapidly evolved into an efficient tool extensively used in a wide variety of civilian applications covering numerous modes of transportation, communication, administration, geodesy, agriculture, etc. The current systems globally available are the US Global Positioning System (GPS) and the conceptually very similar Russian Global Navigation Satellite System (GLONASS). The European Union (EU) has also decided to press ahead with plans to develop Galileo system, a European version of the Global Positioning System (GPS) after the system definition during 1999/2000. The development phase of Galileo is expected, to run from 2002 to 2005 with a deployment phase, leading to a full operational capability in 2008. Choice of Galileo constellation is based on two options, one using satellites in MEO (medium Earth orbit) and the other using a mix of MEO + GEO (geostationary Earth orbit) satellites with Emphasis put on providing high quality services globally and in particular over all of Europe including the northern latitude regions. The MEO constellation will have totally 30 satellites in three equally spaced planes, all with an inclination of 56 degrees at an altitude of approximately 23200 km from the earth surface. Safety requirement is an important factor for a satellite constellation system. In this regard, orbital debris is a serious threat to satellite navigation systems such as Galileo. Therefore risk analysis on orbital debris for a satellite constellation in different positions before launching is desirable. In this paper probability of collision of orbital debris on the global Galileo satellite constellation is calculated and some results are presented
