Hello guys, We're developing an automatic satellite dish pointer controller (for Satellite News Gathering vehicles and other applications), and it will be based on a mini-itx Atom motherboard running debian.
I'm looking for options for measuring the received signal strength and quality for the auto-track and signal lock confirmation, and would like to use an off-the-shelf dvb-s card, supported by a vanilla kernel if possible. I've looked at this list's archive, and found good recommendations for the Technotrend TT-S3200 and TT-S1600. Remote control and hardware mpeg2 decoding are not needed; the 2Ux19" dish pointer controller will have no display (other than a 480x220 touchscreen which cannot show video, and a web user interface). Eventually we'll allow the connection of a monitor if the 1.6GHz fanless single-core Atom can handle the decoding, but that would be just a interesting feature, not a must. The card can be PCI or USB2 (the mini-itx board also has a very useful mini-pcie). I've never used a DVB card, so I'd like to please ask you guys if the dvb-s support under linux can be used in this situation: - no X running - send tuning/cps/etc configuration/commands via command line - get signal strength (dBm?) and quality (BER?), signal lock, and other sat info via command line or api or somewhere in /proc/ for example Considering that this is all I need (and users-do-not-need-to-know-this-is-a-computer stability), are the Technotrend TT-S3200 and TT-S1600 still good bets? Any less featured but still good quality cheaper option? Thank you!
