A satellite navigation or satnav system is a system that uses satellites to provide autonomous geopositioning. A satellite navigation system with global coverage is termed global navigation satellite system ( GNSS ). As of 2024, four global systems are operational: the United States 's Global Positioning System (GPS), Russia 's Global ...

Geostationary satellites appear to be fixed over one spot ...
The United States said Monday that Russia last week launched a satellite that could be part of weaponizing space, a possible future global trend that members of the United Nations Security Council ...
Satellite flare. Top: a simulated animation of a typical Iridium flare. Bottom: Both images show a flare of an Iridium satellite. Comet Holmes can be seen in the right image, slightly above the tree branch. Satellite flare, also known as satellite glint, is a satellite pass visible to the naked eye as a brief, bright "flare".
