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 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.
System Components • Outdoor Unit • 1.2M or 1.8M Parabolic Dish • 303T Antenna Controller • Tunable Low Noise Block (TLNB) • Block Up Converter/Solid State Powered Amplifier (BUC/SSPA)
System Components • Indoor Unit • SATCOM (RF) Case • Linkway Satellite Modem • Frequency Reference System • Monitor and Control Laptop • Modular Power Supply Control • Network (A1) Case • NIPR Integrated Services Router • SIPR Integrated Services Router • KG-175 TACLANE • Turbo IP Accelerator • UPS (A2) Case
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 • Personnel: • RF and MRT: 0621/27 • Data Networking: 0651 • Maintenance: 2844/46 • Embarkation • Site Selection: • Clear LOS to satellite • Stable base, ballast material available
Planning Considerations • Boot Files • Contain satellite, network, and site configurations • Created and distributed by the hub • Cryptographic Material • FIREFLY • PPK • SAA/GAA
Planning Considerations Note: Utilize 2000 Kbps for SWAN data rates at BCOC.
