Principal Accomplishments

The differential phase-shift keying modem built and environmentally tested by Lincoln Laboratory will be transitioned to industry. This modem provides near-quantum-limited communication performance over a very wide dynamic range of received input power and data rates.

  • The Lincoln Laboratory Ka-band Test Terminal was upgraded with enhanced Ka-band instrumentation and will be utilized for post-launch on-orbit characterization of the Wideband Global System Flight 7 through 10 satellites.
  • A real-time network test bed developed by the Laboratory was deployed at Aberdeen Proving Grounds, Maryland. The test bed, which is operated by U.S. Army personnel, is being used to evaluate the performance of vendor equipment and to optimize the configuration of tactical networks.
  • A novel adaptive array antenna design will give fighter aircraft an enhanced communications capability in a highly contested electromagnetic environment.
  • The Protected Tactical Waveform was demonstrated over the air. This test confirmed the viability of providing jamming resistance when the waveform is operating over existing military and commercial transponders.
  • The Laboratory is transitioning operations of the Interim Command and Control Terminals to the U.S. Air Force. These terminals are used to operate the nation’s protected military satellite communications (MILSATCOM) constellation.
  • Flight tests using the Laboratory’s Boeing 707 airborne networking test bed aircraft were completed to support the development phase of the Air Force Family of Advanced Beyond-Line-of-Sight Terminals.
  • A full network and waveform model of an advanced airborne waveform was developed and demonstrated. The waveform is designed to provide increased robustness and capacity while still being able to coexist with the military standard Link 16 tactical data link.
  • The Laboratory designed, implemented, and extensively tested a new Group Centric Networking protocol, which promises to provide improvements in scalability and resilience over traditional mobile ad hoc networking protocols.
  • The final design of a prototype airborne laser communications terminal was completed. This terminal operates over a wide field of regard through a conformal interface.
  • A command-and-control terminal for the Enhanced Polar System was delivered to Clear Air Force Station, Alaska, to support initial terminal checkout.
  • Lincoln Laboratory developed an algorithm that enables tactical radios to synchronize timing without reliance on GPS. Future work will implement this algorithm as a protocol that can be run in software-defined radio platforms.
  • Using a custom-developed high-performance capacity-achieving forward error correction code, the Laboratory demonstrated world-record binary phase-shift keying communication performance of <1.5 photons-per-bit at a 2.88 Gbps data rate.
