Two or more satellites occupying approximately the same geostationary orbital position such that the angular separation between them is very small when viewed from the ground. The satellites appear to be exactly collocated to a small receiving antenna. In reality, the satellites are kept several kilometres apart in space to avoid collisions. An example of a collocated satellite system is the EUTELSAT HOT BIRD(tm) system located at the 13ยบ East geostationary orbital position.
