Abstract
The civilian GPS system was intentionally developed at first with limited precision, and so later several systems were developed to improve the quality and reliability of this and the other civilian systems. Some are ground-based and others are space-based. These use a technique referred to as differential GPS, or DGPS. These were originally developed to defeat selective availability, and to provide higher precision in applications such as civil aviation that require both higher precision as well as system integrity not provided in the basic signals.
