ps

• Commercially

– Bandwidth needs double every 2-3 years

• Meeting the needs

– More satellites

• High Throughput Satellites (HTS)

– More efficient BW Utilization

• Dynamic reallocation of available bandwidth

• Leveraging concepts from Adaptive Coding and Modulation (ACM)

• Wide-band frequency hopping

• Direct sequence spread spectrum (DSSS)

– Improved SATCOM Planning

• Automated systems at electronic speeds

• Dynamically responsive to BW availability

• Smart interference detection and avoidance

• Automatic equipment control at both ends of the SATCOM links

– Reliable Protected Communications

The first step

• Fast and reliable IP traffic

– WAN issues

• Dropped packets, indeterminate latency, variable jitter, packet duplication,

packet reordering, etc.

• TCP/IP generally masks these, and delivers data acceptably

• Many mission critical applications cannot tolerate TCP/IP retransmit/ack

behavior when attempting to deliver consistent data at required rates

– Helpful Protocols

• Packet Forward Error Correction (PFEC)

• Intelligent Retransmission Protocol (IRP)

– End-to-end latency control

– Real-time network health monitoring and reporting

– Cyber attack detection via National IA Partnership (NIAP) and Security

Information and Event Management (SIEM)

– Antenna Site Diversity (and other capabilities) via Digital IF

• Fail-over, WX issues, etc.

• Signal Monitoring

– Tactical tools for troubleshooting and SA

– EMI detection for overt EMI, covert EMI, operator error, equipment

malfunction, etc.

– Strategic tools for enhanced decision making & attribution

– Spectrally-aware / reporting devices

– Self-healing SATCOM devices
