This gives sufficient margin for data reception from direct readout and remote sensing satellites. Designed for optimal maintainability and reliability, the MEOSTM Antenna utilizes the most modern industrial components available. 25 years of satellite ground system experience is built into the design.When integrated with a MEOSTM receiver and processing system, the total unit is a high performance data reception and processing terminal.High reliability• Positioner internals and electronics operate in dehydrated environment• X/Y geometry for lower stress to drive chain• TCP-IP on fibre cable between pedestal and indoor unit• Low mean time to repair, < 2 hours• Drive chain replacement possible with reflector and positioner installed• Stable antenna control unit running Linux, supporting 24/7 operations without operator intervention.• Resumes operation automatically after a power break• Self test and remote diagnostics• Robust computers and servo units.
