Robust Receiver Tracking

Description Data Details

In order to test the proposed tracking schemes real Intermediate Frequency (IF) data affected by equatorial scintillation have been used. The data has been collecting by exploiting a GNSS front-end based Universal Software Radio Peripheral (USRP) installed in Hanoi (21° 2' 0" N / 105° 51' 0" E), Vietnam. The equipment was set-up at the NAVIS Centre, Hanoi University of Science and Technology in collaboration with the European Joint Research Center based in Ispra, Italy and the NavSaS group of Politecnico di Torino/Istituto Superiore Mario Boella based in Turin, Italy.  The installation includes an antenna AT1675-120W SEPCHOKE_MC with Spike Radome, and an Ettus Research USRP Model N200 front-end. Moreover, an external 10MHz Rubidium oscillator has been used to drive the front end in order to minimize the clock noise. Data were collected from February to September 2013 at 5 MSamples/sec in the L1/E1 band in a 20 minutes basis each day after sunset local time in order to catch the ionospheric disturbance peak. A general scheme is reported, respectively in Figure 1. Table 1 summarizes the data details.
