The relative positioning technique involves static and kinematic GPS surveying technique, differential GPS technique, and real-time kinematic technique. These are to be identified before conducting GPS surveying method.

Fast static positioning follows same principle of static positioning. In static positioning, all receivers are kept stationary where as in fast static positioning, only base receiver is kept stationary.

An Operation Control Segment generally involves a master control station, an alternate master control station, commands and control antennas. Monitoring sites were also developed which can access progress of work.

Though re might be an improvement in modern GPS surveying, it lags behind conventional GPS method in terms of accuracy. Conventional GPS methods serve as an ideal method for obtaining accurate output by having less impact of orbital error.

The Global Positioning System can also be determined as NavStar. The main functioning of GPS is to track location of specified place or object using satellites and receiver.

The principle of position determination involves same principle as that of resection in surveying. It indicates location of a set point by help of reference point and n transferring to anor point and locating remaining points. Later, on joining it can end up obtaining result.

OCS can be used in GPS mounted satellites like IIR-M and IIF which are currently in orbit of rotation. These are having high accuracy GPS tracker which can function better than any or satellites.

Among different GPS surveying techniques available, kinematic positioning technique is considered as modern GPS surveying technology. It requires usage of all specialized hardware and software as well as new filed procedures.

There are certain factors which can affect accuracy of position obtained by GPS. Those include position of satellite, atmospheric conditions, satellite clock errors and ephemeris errors.

In process of pseudo ranging, at least four observations are taken. By using se, solution of 2D and 3D GPS positions can be determined. But in general, only three are required for 2D GPS positions.
