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.
