- 24 satellitesThe current GPS constellation consists of 24 satellites1. Each satellite travels in a 12-hour, circular orbit, 20,200 kilometers above the Earth1. The satellites are positioned so that six are observable nearly 100 percent of the time from any point on Earth1. As a result, GPS now effectively operates as a 27-slot constellation with improved coverage in most parts of the world2.Learn more:✕This summary was generated using AI based on multiple online sources.
