Fieldwork GPS report: “The Global Positioning System (GPS) is a space-based radio navigation system that is managed for the United States Government by the U.S. Air Force (USAF), which is the system operator. GPS was originally developed as a military force enhancement system, and it still continues to play this role.
The first type is the Total Station, which is classic equipment and is not only a GPS system. The other two types of equipment used are the Trimble Juno SB handheld and Leica antenna. These two types of equipment are used in similar ways to position points, but the Leica antenna is more accurate and expensive. On the other hand, the Trimble is cheaper than the Leica antenna. This report will show how the devices can be used and a comparison between all three based on the results each type of equipment’s accuracy. Aim: To understand how GPS systems work by using different types of equipment, and to know which device is most accurate. List of equipment: GPS Leica antenna Total Station GPS Trimble Juno SB handheld Explanation and results of fieldwork: (Figure 1: Wild Park area from Google maps) The field work was conducted at Wild Park in Brighton (Figure 1). The first step was set two points as references by using Leica antenna GPS devices. The benefit of these two points is to make the work more accurate. The group started with using a handheld Trimble for each student. Firstly, we opened the device and added information to it. We then made a line across the valley. Finally, each student took random points to show the land in the valley. ...
