Solid-rocket Among the more than 8700 objects larger than 10 cm in Earth orbits, motors use aluminium as a catalyst (about 15% only about 6% are operational satellites and the remainder is space by mass) and when burning they emit debris. Europe currently has no operational space surveillance aluminium-oxide particles typically 1 to 10 system, but a powerful radar facility for the detection and tracking of microns in size. In addition, centimetre-sized space debris and the imaging of space objects is available in the form objects are formed by metallic aluminium melts, of the 34 m dish radar at the Research Establishment for Applied called ‘slag’. -

Rafael was established as part of the Ministry of Defense more than 70 years ago and was incorporated in 2002. Currently, 7% of its sales are re-invested in R&D. Rafael’s know-how is embedded in almost every operational Israel Defense Forces (IDF) system; the company has a special relationship with the IDF. Rafael has formed partnerships with companies with leading aerospace and defense companies worldwide to develop applications based on its proprietary technologies. Offset activities and industrial co-operations have been set-up with more than 20 countries world-wide. Over the last decade, international business activities have been steadily expanding across the globe, with Rafael acting as either prime-contractor or subcontractor, capitalizing on its strengths at both system and sub-system levels.

Satellite Systems
Chapter 18 REST-OF-WORLD (ROW) SATELLITE SYSTEMS For the longest time, space exploration was an exclusive club comprised of only two members, the United States and the Former Soviet Union. That has now changed due to a number of factors, among the more dominant being economics, advanced and improved technologies and national imperatives. Today, the number of nations with space programs has risen to over 40 and will continue to grow as the costs of spacelift and technology continue to decrease.

And it was indeed a fortunate coincidence that the ninth session of the WMO Executive Committee – known today as the WMO Executive Council (EC) – was in progress precisely at this moment, for the EC members were very quick to realize that satellite technology held the promise to expand the volume of meteorological data and to fill the notable gaps where land-based observations were not readily available. -

In standard satellite acquisitions, satellites can take years and billions of dollars to reach operational status. Should there be delays in schedule or on-orbit failures, gaps in data integral to US operations can be lost. -
