There is no need to add another satellite; there are already 24 active ones and six or so on standby. You can usually "see" or "be seen" but somewhere between five and ten satellites at any place on the Earth. Strangely enough, the only limitation is altitude as in an aircraft. Above a certain altitude, GPS does not function. The only thing left to do is to think up new applications for this locating capability and link with with another function, as is done with getting the location of an object like a smart phone or a stolen car and sending this information to whoever needs to know it. A GPS device alone does not have this capability. If need be, GPS locating is very active. as proven by be US military, who is allowing us to use their system.

How I think GPS systems will advance by being more positioning accuracy.

The GPS III satellites will continue to be launched through about 2025. The new GPS satellites can provide better positioning accuracy because of a new set of atomic clocks carried aboard each satellite. Because they have more transmitter power, GPS reception can be more reliable, even indoors and in dense urban areas.

Maybe in a near future the GPS will be able to work with just one satellite capable enough of doing the work of four as it will be more powerful

I think that the gps will advance by putting them in cars, bikes, etc.

I think that GPS systems will advance by telling the user the location of friends or possibly their car. (for those forgetful people)

I think that GPS systems may be able to eventually show what places look like in real time. For example, when using either hybrid or satellite view on Google Maps on the iPhone, it is showing what the location looked like during the last time that Google filmed the location, which is often a few years behind.

I think that GPS systems may advance in many ways! People could possibly add another satellite into the air and measure more thing that we may not yet in today's time.
