Ionosphere Real Time Monitoring System using Septentrio GNSS Receivers

G. Nykiel, M. Figurski

Abstract:	Disturbances occurring in the atmosphere are one of the most important factors affecting the precision and accuracy of GNSS measurements especially during ionospheric storm. Therefore, a precise investigation is extremely important in the context of conducting and developing high frequency satellite measurements. In this paper we present a network monitoring system of the atmosphere parameters, which is currently being developed in the Polish territory by the Centre of Applied Geomatics at the Military University of Technology. Ionospheric parameters are calculated on the basis of 50Hz measurement data received from the reference stations. Among the parameters available in the system worth mentioning are: S4 Index, TEC, ROT and ROTI. They are calculated for both GPS and GLONASS satellites. However, S4 is also calculated for SBAS measurements. The whole system is also prepared to work with the Galileo. In addition to the above parameters, the system includes data such as position determined by the GNSS receiver with covariance matrix, signal to noise ratio for each of the observed frequency, the effect of multipath and the position of satellites. All the information collected in one place and available online allows for continuous monitoring of the ionosphere and its impact on the determined coordinates. The presented system is still under development.
