Our Projects

We work primarily on researching and improving the current state of the UAS industry in both commercial and military applications.

Current Performance

  • NASA Phase II SBIR: Independent Authentication of ADS-B And Transponder Equipped Aircraft Location

    Phase II commercializes the phase I results demonstrating that existing, “trusted” ATC technology, in combination with a tiny, low cost, state-of-the-art micro-avionic, validates GPS-based ADS-B (Automatic Dependent Surveillance-Broadcast) position reports as reliable and accurate for safe navigation and collision avoidance in the NAS (National Airspace System). With minor rule changes, this approach results in safe, fully autonomous V2V (vehicle to vehicle) operation at very high traffic densities within the current Air Traffic Control System (including some UAS) and provides direct paths to accommodate exponential growth of UAS in the future.

  • Navy Phase II.5 SBIR: Identification of Friend or Foe

    R Cubed Engineering is developing a 2087/ZPX Transponder with IFF Capabilities and a KIV-79 Cryptographic Computer. The IFF will be less than 4 oz., under 4 cubic inches in volume, and can be used for mode Mode 5, as well as Mode 3 A, 3C, ES, S and UAT. Pak power is 500 watts, with a diversity and battery option in a double size package. Included is internal GPS so that the device can operate stand alone, or interfaced with a platform. The size is also suitable for use on personnel.

  • Army Phase III SBIR: IFF Flight Testing and Data Capture on a Shadow RQ-7 UAS with Trusted Time Loader

    R Cubed Engineering is designing and developing a Identification Friend or Foe (IFF) transponder system, with capability for Modes 1, 2, 3/A, C, 5, S, and Automatic Dependent Surveillance-Broadcast (ADS-B), with a small form factor to meet the space, weight, and power (SWaP) requirements for Group 2 Unmanned Aerial Vehicles (UAVs). R Cubed plans to interface this transponder directly with the Shadow RQ-7 Aircraft. Using the self-developed R Cubed Emulation of ADS-B Data Capture System (READS), R Cubed is able to perform realtime logging of ADS-B data, comparing outbound ADS-B messages against what is received on neighboring aircraft.

  • Army Phase I SBIR: Micro IFF Transponder

    R Cubed Engineering will conduct a research program to provide the Army with multiple low cost Micro IFF options in Phase I.

  • We are a reseller of both Garmin and uAvionix Products

Past Performance

  • NAVY Phase I and II SBIR: Identification of Friend or Foe

  • NASA High Density UAS Operations with 978Mhz ADS-B

    Flight Safety in the NAS consists of multiple layers: Flight Planning, routing, Radar coverage, transponder coverage, and Dual band ADS-B are examples. R Cubed Engineering focused on optimization of the existing active RF Dual band ADS-B and transponder system for use with anticipated large numbers of SUAS. SUAS will often be operating in areas and at altitudes that will not be visible to the existing FAA infrastructure. They will also have much higher densities of aircraft than the current infrastructure can handle. R Cubed has investigated the use of very small software defined transceiver technology (under 1 oz) tri-band avionics that includes the ability to receive full UAT including ADS-B, ES ADS-B, and Mode A,C, and S transponder responses that can keep track of all transmitting aircraft. The SUAS will also transmit low power UAT ADS-B with dynamically configurable time slots allowing very high density of SUAS. There is also the use of a low power 'all call' interrogator when the operational area is not already interrogated by a local source.

  • NASA Phase I SBIR: Jam Proof and Spoof Proof GPS System

    Automatic Dependent Surveillance - Broadcast (ADS-B) is the most CSWaP compatible safety solution for Unmanned Aerial Systems (UAS) and will be mandated for use by the FAA in the National Airspace System (NAS) by 2020. The ongoing miniaturization efforts will continue to enable a cooperative approach to the integration of UAS into NAS moving forward. A critical limitation of ADS-B is the use of GPS-derived position vector in its broadcast, which can be easily spoofed or jammed, or confused by reflections in urban areas. We present a low-CSWaP solution to secure and verify the GPS integrity using a novel antenna design so that ADS-B can be used as a trusted vehicle to vehicle communications and navigation link for UAS.

  • NASA Phase I SBIR: ADS-B Validation

  • Office of Naval Research (ONR): All Weather Sense and Avoid System (AWSAS)

    Military and other national security agencies have been denied unfettered access to the National Air Space (NAS) because their unmanned aircraft lack a reliable and effective collision avoidance capability. To overcome the constraints imposed on UASs use of the NAS, a new, conformable collision avoidance system has been developed - one that will be effective in all flyable weather conditions, overcoming the shortfalls of other sensing systems. Upon implementation this system will achieve collision avoidance capability for UASs deployed for national security purposes and will allow expansion of UAS usage for commercial or other civil purposes.
