    Hello everyone,

    (Sorry for my bad english, I'm trying to be as clear as possible.)

    Our team is looking for GPS systems that work otherwise than with mobile phone (in altitude, we lose the phones signals). The goal is for an ultra-marathon (Bromont Ultra, a race of more than 30 hours), we must know at all times where our rider is, if he follows the track and tell him where to go in real time.

    - We must be able to load a route (GPX), loaded by us (where the rider is, where he must go).

    - We must be able to be precise at ~10m. near.

    - We must be able to transmit the position of the runner to a base (screen), we are in radio communication (CB) with this base.

    - A system that transmits satellite signals (longitude - latitude - altitude), not mobile phone signals.

    - Need two systems that work in parallel in case one of the two breaks. Can one system harm the other?

    Is it all possible? I really need your advice, I know nothing about GPS. ;)

    Thanks for your help ! We look forward to hearing from you! :)

    It is hard to think of a single device that will do all that you require, here is a list of devices, what they can do and can't do :-

    1) GPS device :
    can accept a downloaded GPX file
    can display route
    can't transmit location (it is only a receiver)

    2) GPS tracker = GPS + cell phone
    can transmit location (via cell phone)
    can't accept GPX file
    can't display a route (no screen)

    3) Smart Phone (running Apps.)
    can accept a downloaded GPX file
    can display route
    can transmit location (via cell phone)
    can receive remote instructions (via cell phone)

    A satellite phone (very expensive) can do a lot of what you want without cell phone communication

    the Garmin Rino can also do a lot of what you want without cell phone communication, note maximum 2Watt transmitter in Canada may not have adequate range
