GPS accuracy refers to the level of precision with which a GPS receiver can determine its position. Several factors affect GPS accuracy, including the number of satellites in view, their positions, and the quality of the received signals. The more satellites a GPS receiver can receive signals from, the more accurate its position calculation will be.

Geometric Dilution of Precision (GDOP) is a measure of the quality of the satellite geometry. It takes into account the positions of the satellites and their relationships to each other and the GPS receiver. A low GDOP value indicates a good satellite geometry, which results in higher GPS accuracy. On the other hand, a high GDOP value indicates a poor satellite geometry, which can lead to reduced accuracy or even no position fix at all.

To improve GPS accuracy and reduce GDOP, it is essential to have a clear view of the sky. Obstructions such as tall buildings, mountains, and dense foliage can block the signals from the GPS satellites, leading to weaker and less accurate position calculations. When using marine GPS systems, it is recommended to install the GPS antenna in a location that provides an unobstructed view of the sky.

Differential GPS (DGPS) and WAAS/EGNOS

Differential GPS (DGPS) is a technique used to enhance the accuracy of GPS positioning. It involves using a reference station with known coordinates to calculate the differences between the actual positions of the GPS satellites and their predicted positions. These differences, known as correction factors, are then transmitted to DGPS-enabled GPS receivers, which use them to improve their position calculations.

One popular form of DGPS is the Wide Area Augmentation System (WAAS) in the United States and the European Geostationary Navigation Overlay Service (EGNOS) in Europe. These systems use ground-based reference stations and geostationary satellites to provide real-time correction data to GPS receivers. WAAS/EGNOS can significantly improve GPS accuracy, especially in areas where DGPS reference stations are not available.
