    hi all ... i have seen the term "satellite receiver" used everywhere in RC hobby "literature" ... can someone please point me in the right direction to understand what it really means?

    i am sort of losing my head trying to figure this one out, so anyone's help would be greatly appreciated!

    thanks in advance.

    You may be referring to the use of multiple receivers for RC systems operation on 2.4 GHz. That practice is used most notably by JR/Spektum radios to avoid multi-path and shadowing problems. Other manufacturers have solved those problems with other methods. See:

    Thanks for your response. From what I figured out, I think a satellite receiver is basically a receiver that outputs a PPM (Pulse Position Modulated) signal. On the other hand, a remote receiver refers to a device that is a combination of a satellite receiver and a PPM decoder, which gives us the multiple PWM outputs on the various channels.

    Please correct me if I am wrong. Thanks!

    I think you are wrong. They are linked to the "mother" receiver for the purpose I mentioned. I do not know what the interface protocol is. I doubt it is PPM, but it might be.
