Detect Unique Identifier
Analyze Signal Characteristics Determine modulation type and symbol rate Determine Convolutional FEC Determine Block Coding FEC
Hand Off to Receiver Program receiver Collect decoded data
CSM decodes data and determines Unique Identifier

Determine Signal Characteristics
DSA can detect Mod type Symbol Rate FEC
Even if Interference is sitting underneath a carrier

Hand Off to Receiver
Use a modem as Receiver Feed data stream back to CSM
Use CSM as Receiver Limited capture range DSA with Decimation give increased
performance

CSM Decodes Unique Identifier
CSM uses agreed standards to search for header containing unique identifier
New standards can easily be added by software upgrade
Mandatory backward compatible hard coded firmware info: Equipment Manufacturer Serial Number Part Number Firmware Revision Number
Optional firmware forward compatible info to be developed by committee

To be proactive in interference reduction the driver for change must be the customer/user.
Satellite operators and vendors can suggest process, system and educational changes; however, without the buy-in of the customer SUIRG’s ability to be proactive and mitigate interference is limited.
The customer or user of satellites must have some ownership of the process and actions taken.
If you support what SUIRG is doing then please consider membership.
