You could still fail to see the value, considering that the 66-satellite constellation went bankrupt just 8 months after its commercial launch last January.
Made up of a 24-satellite constellation encircling the Earth, the GPS system helps hikers, motorists, pilots and mariners navigate their way by giving them an accurate fix on their location.
Building a geostationary satellite that can monitor such emissions for many years is very challenging, and the existing constellation therefore was designed to do just that.
