system overview
System Overview

Note: Mbps=Msps x FEC x modulation factor (QPSK = 2)

  • Provides NIPRNET and SIPRNET connectivity, as well as secure and unsecure voice services for deployed Marine Corps units.
    • On-the-Pause (OTP)
    • Beyond Line of Sight (BLOS)
    • Commercial Ku-band Satellites
    • Carrier sizes (symbol rate) up to 5 Msps (2.5 Msps most common); 1 symbol=1 Hz (bandwidth)
    • Deployable by trained operators in 30 minutes or less
system overview1
System Overview
  • Support Wide Area Network (SWAN) systems purchased by USMC in support of Operation Iraqi Freedom (OIF) in 2004.
  • Several Urgent Universal Need Statements (U-UNS) were submitted by the Marine Corps operating forces that requested SWAN-like capability:
    • VSWAN: submitted by I MEF
    • LSWAN: submitted by II MEF, 2nd MLG
    • HSWAN: submitted by CJTF-HOA
    • GSWAN: submitted by Force Reconnaissance
    • MSWAN: submitted by 26th MEU
    • SI-SWAN: submitted by 2nd Radio Bn

System Overview

Note: FDMA is required for Standard Tactical Entry Point (STEP) access.

In December 2006, contract was awarded for SWAN-D to General Dynamics for procurement.

swan satellite networks
SWAN Satellite Networks

Note: The SWAN-D (V1/V2) can only transmit and receive TDMA Ku-band satellite signals.

Time Division Multiple Access

Bandwidth shared between all sites

Each site assigned a time period to transmit as needed

All sites can typically talk to other sites in hub/spoke via the hub

SWAN Satellite Networks

Note: SWAN-D network operation requires one and only one MRT be present and operating in the system.

  • TDMA networks require a Master Reference Terminal (MRT) to control the timing of the network to prevent data collisions.
  • Each SWAN-D network hub requires a dedicated MRT Suite consisting of:
    • Master Reference Terminal (MRT)
    • Alternate Master Reference Terminal (AMRT)
    • KVM Drawer
    • Network Management System (NMS) Laptop
    • Ethernet Switch*
    • Network Control Computer (NCC)
    • Alternate Network Control Computer (ANCC)

SWAN Satellite Networks

Frequency Division Multiple Access

Also referred to as point-to-point links

Bandwidth is dedicated to sites

Each site is assigned a pair of frequencies to communicate with the other side (1 transmit and 1 receive)

Note: The SWAN-D (V3) can transmit and receive TDMA and FDMA Ku-band satellite signals.

planning considerations
Planning Considerations
  • Personnel:
    • RF and MRT: 0621/27
    • Data Networking: 0651
    • Maintenance: 2844/46
  • Embarkation
  • Site Selection:
    • Clear LOS to satellite
    • Stable base, ballast material available
