- Higher frequencies desirable to reduce atmospheric effects
- The frequencies selected have to balance power needed
for transmission vs. distortion from atmosp heric effects.
- Each satellite transmits on two frequencies, 1575.42
MHz (Link1 or L1)), and 1227.60 MHz (Link 2 or L2), slightly above Cellular
phone band. (Compare to FM ~ 100MHz)
