A Study on Real-Time Signal Observations Acquired by Multi-Frequency Multi-GNSS Septentrio PolaRx5 Receiver

Global Positioning System of Americans, GLONASS of Russians, Galileo of Europeans and BeiDou of Chinese have been continuously transmitting radio signals on various frequencies for the applications of PVT. In addition to them other countries constellations like NavIC of India and QZSS of Japan are providing service in limited area. The multiple constellations can improve the signal quality which helps to the robustness and stability for measuring position and navigation. The main intention for this investigation is for tracking the accuracy and capability of the GPS receivers in addition to the status of PVT for the total number of constellations available at the setup location. This will help in developing various navigation parameters like latitude, longitude, velocity and also studying TEC values related to time. Locality of user will defers depending on the DOP (dilution of precision) values in this receiver. Elevation and azimuthal angles along with SNR of the signal can be observed. Through the help of PolaRx5 receiver, a Real-time observations data were collected from which was setup at our institute located in Kurnool (15o.47'N, 78o.04E). Overall results shows that this Septentrio model of Rx5 can have the capability of receiving minimum of 64 constellation signals along with azimuth and elevation angles, having more accuracy and can study the impact of different ionization effect on different constellations and can be helpful for the future applications on navigation and satellite positions.
