GNSS Limitations During Position Determination and Receiver Rerformance Testing Using Android Mobile Application
Wide GNSS (Global Navigation Satellite System) availability has its advantages, however, in that case the system is exposed to a large number of external influences, from interference with other signals to deliberate blocking and jamming. There is also a huge increase in GNSS user number for both professional and private purposes. The technology of protection and regulation is partly behind the technological development and leaves room for undesired impacts from both natural and artificial causes. Through this paper GNSS errors are described using an android mobile application, "GNSS Analysis Tool", that allows observation of the GNSS signal characteristics.
