In years gone by the surveyor had to rely on instruments like the theodolite and the surveying compass to measure the lie of the land. Today using the Global Navigation Satellite System and a Sokkia GPS system it is far easier for the surveyor to measure the land far more accurately often to within a meter or less. This type of measuring has become extremely popular with professions such as archeologists, engineers and land surveyors based on its incredible accuracy.
While the Sokkia GPS system may seem somewhat complicated it is no different than any other GPS system in that it makes use of 4 orbiting satellites that were first put into place by the US military. These 4 satellites operate on 6 orbital planes that orbit every 12 hours at an altitude of approximately 12.550 miles above the earth's surface.
The satellites broadcast a carrier wave that can then be used by the GPS system to triangulate any position on the ground to within less than a meter in many cases.
In recent years use of GPS by Sokkia and other surveying equipment manufacturers by surveyors and engineers has allowed them to create both two dimensional and three dimensional maps of the terrain. If all they need is two dimensional position or location then access to only three of the four satellites is needed, on the other hand if a full three dimensional map is required then you must have access to all four satellites. Sokkia GPS surveying equipment has become very popular with civil engineers to help them with their fieldwork.
This type of equipment makes mapping, topography, mapping exact locations and earth work far simpler than ever before. By using GPS equipment along with the latest techniques in surveying, it is beginning to edge out the conventional equipment that has been used for centuries.
There are different levels of Sokkia GPS equipment depending on the degree of accuracy you are looking for. For many engineers the accuracy provided by a simple hand held unit is more than sufficient. The hand held unit has become an essential part of most engineers toolboxes and while it may not be the best unit on the market for some tasks in fine for many applications with an accuracy to within one meter.
Where once the total station was the preferred method for laying out trench work, conducting site surveys or completing topographical surveys the Sokkia GPS unit has begun to take over. This is especially true for archeologists and surveyors who find themselves in areas where line of site is not feasible. The GPS does not require line of site as it relies solely on input gathered from the satellites in orbit above the planet. With the right unit it is possible to attain accurate readings to with millimeters.
