    Default Satellite phones....

    Does anyone have experience/info using them, satellite use and satellite shielding from EMP... I've done the consumer search stuff and realize they can be pricey, but how are they as an option in a teotwawki/grid down scenario ???

    The Chinese are currently testing anti satellite weapons.

    I imagine in a WW situation that would be one of the first comms they hit as our country relies so heavily on it for communication.

    I've looked into these too, Sat phones. Yes they are expensive, and if I recall, there is thread here already on it, pros, cons, ect.

    Bottom- line, satellites in orbit are just as susceptible to EMP effects as the hand held unit in your hand (as opposed to being in a Faraday cage), so really it's a matter of the satellites orbital position at the time the EMP effects hit.

    In the end, I passed.

    I've used Iridium based sat phones in the past, I have no experience with Globalstar or inmarsat.

    They are great for areas without cell coverage, but.......

    As other have mentioned they are somewhat expensive, most Sat Phones are around $1000 and a basic plan with 250 minutes with unlimited texting will cost around $129 a month

    Also mentioned sat phones are easily jammed/disrupted due to their very low power output and distance from phone to satellite

    Also the data rate for an iridium satphone is somewhere around 2400 Baud (think very, very old dial -up modem speed)



    However if you want global sat comms (and can live without voice) there is the Delorme InReach http://www.amazon.com/Delorme-AG-009...elorme+inreach

    It's 1/3 the cost of a sat phone and still uses the same Iridium satellite constellation. An unlimited texting/location sharing plan is $50 a month. which is way less expensive than an unlimited texting plan on a sat phone.

    I did an initial search of the site and didn't see much on the subject... There are 2 major systems ... One with stationary satellites over the equator and one with orbiting pole satellites... I would imagine that these satellites are exposed to CMEs and are shielded for them...

    Iridium has the best coverage (true worldwide) followed by inmarsat, and finally globalstar with the worst coverage

    Does the system need 'earthy' support that would cause the system to fail in a grid down event???

    Good question.....I'm not sure about Iridium

    I know without constant monitoring and tiny orbit adjustments the GPS satellite constellation would soon be useless, I would assume the same to be true of any satellite constellation, that they would need terrestrial support to continue functioning

    I wonder if the satellites have on board monitoring to make such adjustments???
