Synchronization between a Vertical Incidence Pulsed Ionospheric Radar & Ionospheric Echoes Receiver
European GNU Radio Days 2023 presentation by Isaac Mario Tupac Davila
In this presentation you will see how to synchronize a Vertical Incidence Pulsed Ionospheric Radar (VIPIR) and an Ionospheric Echoes Receiver (IER), made of an USRP N200, using GNU Radio Companion 3.8 and a generator pulse circuit, which will send one pulsed signal (trigger) in a specific time to beginning the transmission. It is used a GPSDO by the Ionospheric Echoes Receiver to set its time by NMEA's in the reception. Furthermore, you will see how the use of message passing and tags programmed in out of tree blocks affect the synchronization in the acquisition of ionospheric echoes.
