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).
You need to be a member of diydrones to add comments!
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
The Digi m10 satellite modem provides worldwide satellite data transmit and receive capabilities for a wide variety of asset-tracking and industrial remote communications. Operating on the ORBCOMM low-earth orbit (LEO) satellite network, it is designed to enable Machine-to-Machine (M2M) communication with virtually unlimited global coverage and no blockage.

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

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.
