SBIR Success Story

Echo Ridge’s GPS-contested PNT technology solution has been featured in a SBIR success story published by the Air Force.  The article reviews the technology and recent field demonstration performed in Fort Bragg, North Carolina.

Low Probability of Intercept PNT Augmentation Network

Echo Ridge LLC has been awarded a Phase II SBIR contract from the Air Force under topic F16-091 "Low Probability of Intercept PNT Augmentation Network".    Under this effort, Echo Ridge is developing, prototyping, and field testing a Low Probability of Intercept/Detect (LPI/LPD) Position, Navigation, and Timing (PNT) augmentation system using a hybrid frequency hopping, spread spectrum signal-based waveform.  The LPI PNT augmentation will include the ability to take advantage of partial GPS availability, and transparently and seamlessly maintain PNT performance.  Both the beacons and user equipment will be based on SDR technology, allowing PNT and communications functionality to be hosted economically on a common platform. 

Software Defined Radio Test Bed

Echo Ridge, LLC has been awarded a contract from the Naval Research Laboratory (NRL), Solicitation Number N00173-16-R-DH01, “Software Defined Radio Test Bed”. Under this effort, Echo Ridge will provide a complete Software Defined Radio (SDR) Test Bed system, including equipment, engineering support consisting of system design and tailoring/configuration, technical documentation, delivery, setup and training for the test system. The SDR Test Bed will allow NRL engineers to perform high fidelity laboratory testing of RF devices/equipment/systems, including effectively evaluating algorithms on software defined radios (SDRs) in diverse real-world RF environments prior to field deployment. The SDR Test Bed will be based on the Echo Ridge DYnamic Spectrum Environment emulator ("DYSE") product and will include channel emulators, software defined radios, RF enclosures and equipment racks. DYSE is an existing, proven Echo Ridge test asset that emulates varied realistic RF environments in real-time to support testing of a broad variety of wireless devices and systems in the convenience of a controlled laboratory environment. The test bed will include provision for simultaneous testing of up to 24 GNU-radio-compatible SDRs.

Spectrum Sensing & Sharing by Cognitive Radios in PNT Systems

Echo Ridge, LLC has been awarded a Phase II STTR contract from the Air Force under topic AF15-AT23 “Spectrum Sensing & Sharing by Cognitive Radios in PNT Systems”. Under this effort, Echo Ridge is developing an architecture and algorithms to support spectrum sharing for position, navigation, and timing (PNT) that focuses on spectrally congested operational scenarios. The architecture defines the new functionality and necessary improvements to the PNT elements, spectrum sensing elements, and communication elements to support spectrum sharing for PNT. The end result will be a system whereby measurements in the discontinuous and disparate shareable spaces can be used jointly by MGUE to estimate PNT. In Phase II, we will be developing and demonstrating prototype hardware in a series of operationally realistic laboratory and field test environments.

Low Probability of Intercept PNT Augmentation Network

Echo Ridge LLC has been awarded a Phase I SBIR contract from the Air Force under topic F16-091 "Low Probability of Intercept PNT Augmentation Network".    Under this effort, Echo Ridge will design and performance characterize an LPI/LPD PNT augmentation system (including beacons and user equipment) using a hybrid frequency hopping, spread spectrum signal-based waveform which we believe can achieve compliant performance in ground applications.  In addition to PNT and LPI performance, a key criteria in our design is operational utility measured in terms of flexibility/lack of constraints and SWaP-C.  For operational flexibility and low cost, it will include battery and prime-powered beacons, and vehicular and dismount user equipment.  Both the beacons and user equipment will be based on SDR technology, allowing PNT and communications functionality to be hosted economically on a common platform.

Air Force EW Training Tool Delivery

Echo Ridge LLC has been awarded a funding enhancement for the Phase II STTR contract from the Air Force under topic AF14-AT28 "Electronic Warfare:  EMS Monitor & Broadcast Training Capability Enhancement".  Under the enhancement, additional EW capabilities will be developed to support realistic warfighter training in congested and contested RF environments.

Wearable Precision PNT in GPS-challenged Environments

Echo Ridge LLC has been awarded a Direct-to-Phase II SBIR contract from the Air Force under topic AF153-002 "Handheld Dismount Kit for Persistent, Precision Navigation in GPS-challenged Environments for Military Operations".  Under this effort, Echo Ridge will build and test handheld prototypes of the Augmented Positioning System (APS) using previously developed components.  APS will use highly abundant and globally available RF signals of opportunity (SoOPs) to provide error-growth-constrained position in GPS-challenged environments.  APS employs an SDR architecture which allows it to use a broad variety of terrestrial and space based SoOP sources in a low weight/power package.  Dismount position as well as SoOP position estimations are shared between dismounts using existing low-bandwidth, latency tolerant radio links.  The light-weight APS module is easily worn by dismounted military forces; can operate on batteries for extended periods of time; can operate in day or darkness, in inclement weather, and in environments with little or no infrastructure such as remote deserts and forests.  The project will develop demonstrable technology within the first year, achievable due to the significant progress and risk reduction that has been carried out under previous contracts.

Air Force EW Training Tool Delivery

Echo Ridge LLC has been awarded a Phase II STTR contract from the Air Force under topic AF14-AT28 "Electronic Warfare:  EMS Monitor & Broadcast Training Capability Enhancement".  Under this effort, Echo Ridge will build and deliver a suite of prototype EW training tools to support realistic warfighter training in the congested and contested RF environments expected in future operational engagements.  The tools consist of an opposing force broadcast capability and an Electromagnetic Spectrum (EMS) monitoring capability which supports multiple EW functionalities.  The broadcast tools will support a wide range of commercial and military waveform synthesis and playback capabilities.  The EW tools will be based on Echo Ridge’s previously developed Software Architecture for Intelligent Jamming (SAIJ); an open integrated development environment (IDE) for EW.  This capability will offer signal detection, identification, and characterization functions that may be used by warfighters to conduct effective EW.  The tools will be based on the extensive use of the latest modern software defined radio (SDR) technology, commercial of the shelf (COTS) hardware, and open-source software, providing a highly economical, and easily upgradable platform basis.

Air Force GPS Enhanced Dynamic Spectrum Access Phase II Enhancement Contract Awarded

Echo Ridge, LLC has been awarded an 18-month Phase II SBIR enhancement contract from the Air Force under topic F121-158 "GPS Enhanced Dynamic Spectrum Access." The enhancement effort includes the design, development and delivery of prototype performance enhancement algorithms operating on host software defined radio (SDRs), and developmental testing and functional performance demonstrations of the prototype algorithms.  These efforts build on Phase II results where we developed algorithms which provide cross-application performance enhancements to networked software defined radio and navigation systems.  These algorithms are enabled by dynamic spectrum access (DSA)-based cognitive radio (CR) and GPS navigation functionality operating on a common software defined radio (SDR) platform in a cognitive network (CN).  The algorithms exploit functionality and information traditionally present in each organic application to provide mutual-benefit through tightly coupling measurements in the multifunction common SDR-cognitive network context.
