During the 1970s and 1980s Israel began developing the infrastructure needed for research and development in space exploration and related sciences. Israel launched its first satellite, Ofeq-1, from the locally built Shavit launch vehicle on September 19, 1988, and has made important contributions in a number of areas in space research, including laser communication, research into embryo development and osteoporosis in space, pollution monitoring, and mapping geology, soil and vegetation in semi-arid environments. Israel is among the few countries capable of launching satellites into orbit and locally designed and manufactured satellites have been produced and launched by Israel Aerospace Industries(IAI), Israel's largest military engineering company, in cooperation with the Israel Space Agency. The AMOS-1 geostationary satellite began operations in 1996 as Israel's first commercial communications satellite. It was built primarily for direct-to-home television broadcasting, TV distribution and VSAT services. Further series of AMOS communications satellites (AMOS 2 – 5i) are operated or in development by the Spacecom Satellite Communications company, which provides satellite telecommuncations services to countries in Europe, the Middle East and Africa. Israel also develops, manufactures, and exports a large number of related aerospace products, including rockets and satellites, display systems, aeronautical computers, instrumentation systems, drones and flight simulators. Israel's second largest defense company is Elbit Systems, which makes electro-optical systems for air, sea and ground forces; drones; control and monitoring systems; communications systems and more.
