The used ionosondes are bistatic PRC radar transmitting and receiving almost continuous wave. The surveys will allow to map the ionosphere over large regions for the verification of theoretical models of the global ionosphere and local disturbed ionospheric conditions, and to investigate possible ionosphere- lithosphere coupling phenomena. Oblique surveys involve the placement of TX and RX in different points, even thousands of kilometers away. Iononet is a network of severall transmitters and receivers ionosondes sincronized to work at the same time. The PRC ionosondes have been built using Software Defined Radio (SDR) devices that act as transmitter or receiver of the Radio Frequency (RF) signals. They generate all the signals necessary for the operation of the ionosondes such as the GPS signals acquisition used for time synchronization, the triggering of the RF power amplifier for long distance sounding, and the antennas switches. The SDR device is able to convert into an RF signal a pseudo random numerical sequence generated by a Personal Computer (PC) or receive and convert the RF antenna signals into a pseudo random numerical sequence on the PC The receiving PRC ionosonde, placed at one of the ionospheric observatory, allows receiving and detecting at the same time the pseudo random coded signal transmitted contemporarily from different ionosondes, multiplying the observation possibilities of the ionosphere from different directions. It is possible to use the code with different random seed (used as station identifier parameter) at the transmitting ionosondes and using a precise time synchronization between transmitting and receiving ionosondes; the high precision is obtained using a GPS Disciplined Oscillator (GPSDO).
