Teleoperations (or Teleops) is critical to current military tactical needs and so there is an urgent need for enabling technologies and quick deployment. The SRW-UAG PHY has new mission enabling capability such as broadband data rates, discontinuous spectra, and robustness to airborne dynamics and terrestrial multipath. In addition, the SRW-UAG PHY can be quickly deployed using existing JTRS platforms and the upper layers of SRW, i.e. without any new hardware or waveform development. During previous SBIR phases, TrellisWare has demonstrated the capability of the SRW-UAG PHY in the field using SDR development platforms. As part of this Phase II.5, TrellisWare will port the SRW-UAG PHY to a JTRS platform and thus enable more rigorous field testing and participation in Army NIE tests.

Phase II.5 proposal, extension of Phase II contract N00014-09-C-0510. Free-space Laser communications (Lasercomm) or free-space optical (FSO) communications is rapidly gaining traction as a next-generation line-of-sight (LOS) wireless technology for both commercial and military applications. Over short time scales (e.g., milliseconds), these high-bandwidth links are plagued by scintillation fading due to atmospheric turbulence and (possibly) boundary layer effects (e.g., at the surface of fast moving aircraft in ship-air links). Although somewhat analogous to the mutlipath-induced fading that is familiar in mobile RF communications, optical scintillation-induced fades typically span thousands to millions of symbols rather than tens to hundreds due to the higher symbol rates and longer fade durations. Consequently, solutions for combating fading in RF links do not readily extend to Lasercomm. During Phase I, TrellisWare showed that a modern coded-protocol can offer dramatic throughput improvements over existing state-of-the-art baseband approaches in scintillation-induced fading FSO links. In Phase II.5, TrellisWare proposes to design and implement a hardware prototype FSO modem, to include optics, to demonstrate that our approach can be effectively and efficiently implemented for use on real maritime and expeditionary links. TrellisWare has already received interest from its FSO industry partners in the proposed hardware thus demonstrating a clear path to commercialization during Phase III and beyond.

Under this multi-phase SBIR program, TrellisWare is developing a low size, weight, and power (SWAP) public key (PK) cryptosystem that combines any off-the-shelf PK algorithm with an innovative key generation protocol that allows multicast groups to securely generate common public/private key pairs via messaging over a non-secure wireless channel. The resulting cryptosystem will provide the benefits of public key cryptography i.e., dynamic network support with features currently found only in symmetric systems i.e., energy efficiency and native multicast support. During Phase I, TrellisWare developed a series of group key generation protocols, the most sophisticated of which operates in a fully ad hoc manner and requires only O(log t) transmissions to generate an encrypt/decrypt key pair for a t-node multicast group at steady state. For Phase II, we propose a Base program that combines basic research with protocol development, integration, and demonstration. During the Phase II Option, we will first integrate an off-the-shelf, low SWAP encrypt/decrypt module with our tactical MANET products; a series of operationally relevant test exercises will then be performed to demonstrate our low SWAP cryptosystem in hardware.

ABSTRACT: There are many situations where military receivers require coordinated universal time (UTC) in GPS-denied environments. TrellisWare has already developed and fielded a TRL 9 military waveform that synchronizes to microsecond-to-millisecond accuracy without GPS. This waveform provides a feasibility proof for the capability sought by the Air Force. In this program, TrellisWare will identify and develop the lowest-complexity and most cost-effective solution for realizing our proven techniques for secure time delivery via the existing commercial and tactical wireless infrastructure. BENEFIT: The techniques developed in this program could be applied to provide time sync and wireless localization capabilities to commercial and first responder radios that are used in GPS-denied environments. Examples include mining, tunnels, and post-disaster recovery efforts.

The Navy"s focus continues a decade-long shift from blue water to green water operations. The Littoral Combat Ship (LCS) is a key component of this new focus, providing a flexible platform which can be configured to fulfil a wide variety of roles, including anti-submarine and anti-surface warfare, mine countermeasures, and special operations support. Several of these roles require the LCS to remotely operate unmanned vehicles. No currently available radio system is capable of supporting the LCS and UVs in their mission. In this program, TrellisWare Technologies, Inc. will leverage its deep experience with anti-jam (A/J) waveform design as well the MIDS JTRS terminal to design, prototype, and demonstrate a next-generation, highly-robust A/J waveform that will operate on a MIDS JTRS-compatible module. At the end of the Phase I Base program, we will demonstrate the concept waveform in the final MIDS JTRS compatible hardware form-factor in a realistic jamming environment.
