Introduction

As a leading provider of satellite communication solutions, SatHarbor is proud to offer the Comtech CDM-570A series satellite modem. Known for its robust performance, advanced Forward Error Correction (FEC) options, and support for Comtech’s patented DoubleTalk® Carrier-in-Carrier® technology, the CDM-570A helps organizations achieve efficient and cost-effective connectivity. Whether deployed for emergency satellite connectivity, disaster recovery satellite solutions, or offshore satellite communication for oil and gas applications, this modem excels in diverse environments—including the Ku-band networks in Central Asia—thanks to its flexible design and intelligent bandwidth management.

Key Features & Technical Highlights

1. VersaFEC-2 and Multiple FEC Options

   • Supports VersaFEC-2 high-performance LDPC, VersaFEC low-latency LDPC, Turbo Product Codes (TPC), and more.
   • This versatile approach ensures optimal data transmission rates with minimal latency, making it ideal for real-time operations.

2. Carrier-in-Carrier® Bandwidth Compression

   • By allowing transmit and receive carriers to share the same transponder space, DoubleTalk® Carrier-in-Carrier® slashes bandwidth needs and lowers operating costs.
   • Carrier-in-Carrier Automatic Power Control (CnC-APC) enables the modem to adjust for rain fade and maintain total composite power, boosting network availability.

3. Wide Data Rate Range

   • Handles data rates from 2.4 kbps to 10.239 Mbps, accommodating everything from low-data SCADA requirements to high-throughput corporate data exchanges.
   • Multiple modulation schemes (BPSK, QPSK, 8PSK/8-QAM, 16-QAM, 32-ARY) let users balance performance with spectral efficiency.

4. Flexible Frequency Bands

   • The CDM-570A model supports 70/140 MHz IF (50–90 MHz or 100–180 MHz).
   • The CDM-570AL or CDM-570A-L-IP covers the L-Band range (950–2250 MHz).
   • This adaptability suits both traditional satellite bands (C, Ku, and X) and higher-frequency Ka-band configurations.

5. Advanced Network Management

   • Seamless integration with Vipersat Management System (VMS) enables dynamic SCPC allocation and on-demand bandwidth—key for mobile backhaul and large enterprise networks.
   • Automatic Uplink Power Control (AUPC) adjusts transmit power to maintain link quality, especially crucial for harsh environments or varying weather conditions.

6. IP/Ethernet Traffic and QoS

   • The -IP models include a high-performance packet processor supporting header/payload compression, advanced Quality of Service (QoS), and VLAN configurations.
   • These features reduce overhead, optimize throughput, and prioritize mission-critical data—especially important in congested or latency-sensitive networks.

Typical Application Scenarios

1. Emergency & Disaster Recovery

   • The modem’s robust design and optional ruggedization ensure reliable operations for emergency satellite connectivity during natural disasters or critical outage events.

2. Offshore Oil & Gas

   • High-performance networking is indispensable for real-time data gathering on drilling platforms. The CDM-570A’s SCPC/TDMA modem approach and Carrier-in-Carrier® efficiency lower bandwidth costs.

3. Government & Military

   • Secure, low-latency connectivity is essential for government agencies. The modem’s advanced FEC, remote M&C (monitor & control), and encryption-friendly design support mission-critical environments.

4. Telecom & ISP Services

   • For providers extending coverage to remote regions—such as villages in Central Asia—the flexible data rates and high spectral efficiency facilitate broadband internet, VoIP, and backhaul for mobile networks.

Best Practices & Considerations

• Choose the Right ModCod: Align the modem’s modulation and coding (BPSK to 32-ARY) with your link budget to maximize throughput without sacrificing link reliability.
• Enable CnC-APC: For two-way links in rain-prone areas, enabling Carrier-in-Carrier® Automatic Power Control maintains service quality during downpours.
• Utilize QoS & Compression: In IP/Ethernet-driven networks, activating QoS and header/payload compression can substantially reduce overhead and cost.
• Regular Maintenance & Monitoring: Schedule routine checks, firmware updates, and leverage remote M&C to detect performance degradation early.
• Consult with Experts: Always involve experienced satellite communication engineers (like the team at SatHarbor) to optimize your SCPC or TDMA network configurations.
