Single Channel Per Carriar

SCPC is used for economical distribution of broadcast data, digital audio and video materials, as well as for full-duplex or two-way data, audio or video communications.

In an SCPC system, user data is transmitted to the satellite continuously on a single satellite carrier. The satellite signal is received at a single location, in the case of a point-to-point system, or at many locations in a broadcast application, providing hubless connectivity among multiple sites.


SCPC got its name from the older analog transmission technology, when a single satellite channel could carry only one data carrier. With today's digital technology, SCPC can actually operate in a MCPC (Multiple Channel Per Carrier) mode, with several data carrier multiplexed into a single digital aggregate. For example, two earth stations transmitting 64 kbps carriers to each other can actually provide several compressed digital telephone circuits as well as full-time low speed data circuits if proper voice/data multiplexing equipment is added to each basic system.

Examples of SCPC VSAT Applications:

• Credit authorizations
• Highspeed access to IP networks
• Replacement of terrestrial circuits
• PABX extensions
• Backup circuits for redundancy or diversity
• Inventory management
• Supports true multimedia capabilities--voice, data, fax and e-mail
• Access to remote locations where high-speed terrestrial

       digital connectivity is not available
• Policy and account management
• Method to bypass PTT’s or local infrastructure
• WAN connectivity
