These are, namely, a 20-channel GPS receiver, GPRS modem, display, and a sound
With the introduction of PS services by the GPRS subsystem it became necessary to extend the MAP protocol to the interfaces between GPRS support nodes
GPS satellite MAP navigation operate simultaneously to form a constellation that orbits around the Earth every 12 hours. Ground stations can track each satellite's location. GPS satellite MAP navigation synchronize with each other so they can repeat the signals and transmit them at the same time. Transmitted signals arrive at the GPS receiver at slightly different times because some satellites are farther from Earth than others. To calculate the distance of the GPS satellites, you must determine how long it takes the signals to reach the receiver. The GPS satellite MAP navigation receiver estimates the distance to at least four GPS satellites by calculating their positions in three dimensions.
A GPS satellite MAP navigation system in your car–with the help of global positioning satellites (GPS) sending out synchronized signals to wandering souls all over the planet–pinpoints your location with great accuracy. When your position is compared with the GPS satellite MAP navigation system's embedded maps, frustrating voyages of all kinds turn into precision-guided tours.
這些是，即，一個20通道的GPS接收機，GPRS調製解調器，顯示和聲音

GPS衛星地圖導航同時運行，形成一個星座軌道繞地球每12小時。地面站可以跟蹤每個衛星的位置。 GPS衛星導航地圖相互同步，這樣他們可以重複的信號，並發送它們在同一時間。發送信號到達GPS接收機的時間略有不同，因為一些衛星是更遠離地球比其他。為瞭計算GPS衛星的距離，必須確定需要多長時間的信號到達接收機。 GPS衛星地圖導航接收機通過計算在三維空間的位置估計到至少4個GPS衛星的距離。
