It is the most widely used type of WebThe GPS satellites broadcast on two carrier frequencies: L1 at 1 575.42 MHz and L2 at 1 227.6 MHz. Each satellite broadcasts a spread-spectrum waveform, called a pseudo-random noise (PRN) code on L1 and L2, and each satellite is identified by the PRN code it transmits. There are two types of PRN codes. blue advantage arkansas claims address
