GPS is primarily a navigation system for real-time positioning. However, with the transformation from the ground-to-ground survey measurements to ground-to-space measurements made possibly by GPS, this technique overcomes the numerous limitations of terrestrial surveying methods, like the requirement of intervisibility of survey stations,

the capabilities of GPS to give more benefits to the civil community. In addition to the existing GPS signals, new signals will be transmitted by GPS satellite; see Figure 5. Moreover, this will increase the robustness in the signals and improve the resistance to signal interference. This definitely will lead to a better quality of service (QoS).

2.1.2 GPS Accuracy Factors The accuracy of the basic GPS system is approximately 15m. GPS accuracy can be affected by a number of factors including the Selective Availability feature, atmospheric delays, satellite clock and orbit errors, multipath signals, signal strength, and satellite geometry relative to the user.

PART III: GPS Signals "GPS signals travel 20,000 kilometers from a medium earth orbit and arrive at the earth's surface with a power density of only 10 -14 to 10 13 watts/m2." Electro-magnetic whispers: - Enable high-precision ranging even in the presence of natural noise and modest amounts of man-made interference.

GPS History, Chronology, and Budgets 241 system concept that emerged is what is known today as the NAVSTAR Global Positioning System. In December 1973, DoD granted the JPO approval to proceed with the first phase of a three-phase development of the NAVSTAR GPS.11 Testing the GPS Idea (1974-1979). The first phase of the GPS program was in-

Like any other approach, GPS based method also has advantages and disadvantages. It is simply one of the many tools that should be in the surveyor's tool box. Let us now discuss about some of the advantages and disadvantages of GPS over conventional surveying methods. 3.2.1 Advantages The several advantages of the GPS satellite surveying ...
