UART base satellite terminal?

Hi,Is there any wireless terminal that base on satellite communication(not base on radio something like xbee, wifi, bluetoth)?That can be use with Micro controller(Arduino) base on serial(UART).

  • Hi Thanks for your reply.

    I don't know much about satellite communication.

    Am I need to pay for sending data.

    It is no need in Xbee radio.

    Can I continues sent data after 90 days on M10 Development kit.

  • this is what i found regarding satellite based communication

    in short:
    tha throughput is to small and the latency is to high



    Digi M10 Satellite Modem - Provides World wide connectivity for M2M Apps

    For Satellite Connectivity for M2M Applications we have three kinds of Connectivity .

    LEO – Low Earth Orbit
    ‐ Satellites in Low Earth Orbit are within 1000 miles of the surface, and routinely go around about 18 times every day
    MEO – Medium Earth Orbit
    ‐ Satellites in Medium Earth Orbit are up around 6000 to 20,000 miles, and orbit generally twice/day (some are more)
    GEO – Geosynchronous Earth Orbit
    ‐ Satellites in geosynchronous orbit are placed there so they remain fixed over the Earth's surface, and go around exactly once per day

    For the above connectivity , we have 3 Satellite service providers


    Orbcomm
    ‐ Mobile to Sat “Up” Link: 148‐150 MHz
    ‐ Sat to Mobile “Down” Link: 136‐138 MHz
    Satellites Type is LEO with 29 Satellites , Message capability of 6-8K Bytes , Two way communication, Latency is 3-15 Mts, & heavily Focused on M2M

    ‐ Inmarsat
    ‐ 16xx MHz Mobile up‐link;15xx Mobile down‐link
    ‐ 4 GHz Earth Station down‐link
    ‐ 6 GHz Earth Station up‐link
    Satellite Type is GEO with 11Satellites , Message capability of 10-20 Bytes , Two way communication , Latency is <1 Mn . Focus is not heavy on M2M Applications’

    Iridium
    ‐ Mobile to Sat Link: 1616 ‐ 1626.5 MHz
    ‐ Sat to Ground Link: 29.1 ‐ 29.3 GHz up‐link; 19.1 ‐19.6 GHz down‐link
    ‐ Sat to Sat Link: 22.55 ‐ 23.55 GHz
    Satellite Type is LEO with 66 Satellites , Message capability of 100-200 bytes , Two way communication , Latency is 30 seconds to 2 Mts . Is New to M2M Applications
