Controlling of L-Band Switch Matrix
Overview
- Headquarter of e.g a tv broadcaster which receives transmissions from other television stations or SNG vans via satellite
- A number of moveable and fixed antennas
- Multiple Digital Receiver (IRD) with different features (e.g. encryption)
- Every antenna could be assigned to every IRD
System overview
Network structure
- Primary M&C Server controls the devices
- Backup M&C Server syncronises the current configuration with the primary server
- The User can access the system from an unlimited number of client PC's
- In case of trouble with the primary server, the serial connections to the devices are switched over to the backup server and the system is ready to use in a few minutes
Network structur
Using the M&C system
- Select the antenna and point it to the satellite (left)
- If the antenna is already is locked it cannot be moved anymore
- Easy pointing with a set of predefined satellite positions (presets)
- Adjust the receive parameter of the IRD Chain
- manual setting of frequency, symbol rate etc.
- or loading of predefined presets
- The system selects automatically the L-Band In- and Output of the Switch Matrix regarding the current antenna, frequency and polarization selection.
Operator Interface
IRD Chain Device
- Logical device to simplify the handling without knowing how the ports of the matrix are connected to IRD's and antennas
- The IRD selection defines the output port of the switch matrix
- The selected antenna, frequency and polarization defines the input port of the switch matrix
- IRD Chain does the LO-frequency translation
- Used IRD Chain can be locked
