It's kind of surprising that single satellites can still be so crucial, given that we have at least three operational navigation systems which phones can easily use (GPS, GLONASS, BeiDou and Galileo). Are those not all truly global?
- abfan1127 3y agoWhile these may be truly global, I don't know that all "GPS" satellites are. They reference a specific brand of satellites. Their website mentions that this satellite only services the asian pacific region.
- bluGill 3y agoThis is a navigation satellite, it is a communication satellite that sends information you cannot get via GPS. The speed of light in the atmosphere is not a constant, this satellite is sending corrections so you can account for that (that is there is some other GPS 'near' you, at a known location, and then it compares where GPS says it is to where it really is and you subtract that difference).
