Welcome to the Global Space Situational Awareness Sensor Database, an online compendium of SSA sensors around the world.
There are many different technologies used for SSA. Radars (both mechanical and phased array) provide an accurate range to a target but are expensive to build and operate and require large amounts of power. Optical telescopes can be cheaper and can cover a much wider area, but can only operate at night and in good weather. Lasers can also be used to get very precise locations, especially large geostationary satellites. In many cases, the most accurate position of a space objects is derived by combining observations from multiple types of sensors.
