<name>eSWua IONORING tool: acquisition of GNSS observables from RING network</name>
<description>
IONORING input data are GPS carrier phase observables on L1 and L2 frequencies (1575.42 MHz and 1227.60 MHz, respectively), Coarse Acquisition (CA) code observables on L1, and Y-code observables on L2 that are broadcasted at a 1-second rate through Networked Transport of RTCM via Internet Protocol (NTRIP) by the selected receivers. Additionally, navigational information (i.e., orbital parameters for GPS satellites) are retrieved by NTRIP streaming from the considered receivers or, alternatively, by the IGS navigational information streaming.
