RTTC Electro-Optical Sensor Flight Evaluation
Laboratory (EOSFEL)
The EOSFEL is a state-of-the-art facility for
testing EO missile guidance sections and control
systems. The facility provides a real-time
closed-loop high-bandwidth 6 degree-of-freedom
(6-DOF) HWIL test environment that provides a
non- destructive environment for performing
missile subsystem testing throughout the weapon
system life-cycle.

RTTC Modeling and Simulation Testbed (MSTB)
The RTTC MS Testbed is Helping to Define a
Re-usable Common Architecture to interface with
the Army Test and Evaluation Command (ATEC)
Virtual Proving Ground. Initial implementation
focused to Support Army Tactical Missile
Simulations and HWIL Facilities.

Federation Execution

• Configured a 20 Mbit/Sec Bridged Permanent
  Virtual Circuit (PVC) between RTTC and WSMR
• Data Throughput Requirement
• Real-Time IR Scenes of 5000 Byte packets at 30
  Hz.
• Utilized Point to Point instead of Multicast due
  to Routing Issues
• To Support Point to Point Networking
• Had to Modify RID File
• Utilized Directions Found Under the HLA Homepage
  RTI FAQ for Does the RTI Work Outside the
  Confines of a LAN
• Had to Modify Federation Execution Data (FED)
  File
• Modified the FOM to Change the Transport
  Mechanisms for Every Attribute from Best Effort
  to Reliable
• Generated New FED File
• Distributed New RID and FED File

Network Results

• Bridged PVC between RTTC and WSMR
• Ping Results 5000 Byte Packet size at 30 Hz
• Sent 2,296,000 Packets
• Received 2,295,731 Packets
• Lost Packets 269 for .021 Loss
• Latency Tests
• Using the DMSO Benchmark Tools and the RTI 1.3v5
  Running on 1 Processor of the HPC with Reliable
  Transport
• Max One-way 37.96 msecs
• Min One-way 34.87 msecs
• Mean One-way 36.38 msecs
