What is a GPS. A GPS is a navigational system. Robert Easton and other co workers were the first people yo actually get the idea a navigational system in 1973. The GPS wasnt built till 2003. The GPS is made by different by different compainies a popular brand is Garmin. Gramin spent about 12,000,000 on starting the program.To actitave the gps you type in the location you are planning to go to. The Gps will begin the journey as you listen to its signals on where to go. The GPs is smart and handy and when you have taken a wrong route the Gps recalculates and takes you back to the road you were on. The Gps can be found in cars and phones. The Gps is becoming popular by the minute and will this energing technolgy fad or will it live on? What came before the Gps was the Compass. A Compass is a navigational instrument modefied my the magnetice field around the earth. I think that in the future we might create a 3d maps that we can fit in our pockets like a cell phome almost. By pressing a button on teh 3d map we can activate a hologram of the city or town you are living in. If you are moving top a different country you would able to change the settings to match that country. I hope that you have learned a bit about the Gps, what can before, and whats coming after.
