Geotag Accuracy

Geotag accuracy is the accuracy of the raw GPS data collected by the GPS reference station. When the accuracy of this data is low, it has an effect on your final data in Kespry Cloud.

The most common reasons for geotag accuracy being low are the following:

1. Power lines/transformers: Ensure your GPS reference station is mounted at least 660 feet (200 meters) away from any power lines. Although this does not always affect the geotags accuracy, there may be cases where it does. 

2. Multipath: Multipath refers to errors associated with GPS signals reflecting off buildings or other objects before reaching the GPS reference station. It is best to mount your GPS reference station away from any buildings, vehicles, or structures.

3. Number of satellites available during your mission: In general, the more satellites the GPS reference station is able to receive signals from the better, however, keep in mind that the number of satellites in a given area at any given time fluctuates. To let the GPS reference station receive signals from as many satellites as possible, it should be mounted in an area with an open view of the sky.
