A minimum of 24 operational Navstar satellites are required for the GPS system to work effectively. These satellites are strategically positioned in orbit to ensure global coverage and accurate positioning for GPS receivers on Earth.

The concept of GPS (Global Positioning System) was developed in the early 1970s by the United States Department of Defense. The first GPS satellite was launched in 1978, and the full constellation of 24 operational satellites was completed in 1993.
Around 19591959? Not likely since GPS didn't exist then.The first GPS satellite was launched from Vandenberg Air Force Base on February 22, 1978. However, it wasn't until the mid-1980s that commercial GPS equipment appeared on the market.

Early GPS technology began in the 1960's with the United States military. The launch of GPS as we know it happened in 1973, and was called NAVSTAR.
GPS is the successor to several earlier systems of measuring position. Loran in WWII, then Radar, Navstar, and so on. GPS is such a complex system that it is doubtful if any one person can understand all of it.
Satellite navigation was first developed in the United States, primarily through the Global Positioning System (GPS) project initiated by the U.S. Department of Defense in the 1970s. The first satellite, Navstar 1, was launched in 1978, marking the beginning of operational satellite navigation. The system was designed for military use but later became available for civilian applications, revolutionizing navigation worldwide.
