Current Projects

1) GTMR currently has staff supporting:

  • NAVSEA NSWC Dalghren, VA
    • Air Force Hibeam/Malet
    • Air Force C2ISR Division
    • Special Aircraft Army Test Program
  • NAVAIR Programs, including:
    • EP-3E Aircraft
    • Navy Component Airborne Common Sensor
    • P-8
    • Navy Special Mission Aircraft
    • Office of Navy Intelligence (ONI)
    • Other advanced Research and Development Projects

2) GTMR responds to current and anticipated requirements in the design and prototype of Omni narrow- and broad-band antennas with bandwidths up to 5GHz. Our family of lightweight, low-cost spinning and Doppler direction finding antennas continues to evolve as platform, operating environment, and target set specifics are defined by our customers and partners. We "quick reaction capability" design and fabricate specialty antennas and hardware including highly directional high gain antennas against point- or RF range specific targets for specific vehicles in minimum time; often in less than five days. We are also working on systems capable of exploiting HF targets from very small vehicles.

3) Ruggedization and qualification of commercial off the shelf components for military and harsh environments. These efforts have included vibration isolation for sensitive drive components in computers to on-site test participation where our engineers are called in to participate, analyze failure modes and provide the solutions to fix the problem and qualify the unit.

4) Design and production of a wideband (1GHz) RF filter assembly capable of removing/mitigating harmonics from the output of high power (100W+) transmitters, with insertion loss less than 2dB and 30+dB of isolation. The prototype weighs less than six pounds, is automatically controlled, and is currently installed in operational aircraft. We are in the preliminary design stage for a similar system capable of handling transmitter power up to 500 watts. We are in the final stages of the design and test of narrow band filter capable of removing/mitigating harmonics generated by metallic propellers that severely impact the performance of array type DF systems.

5) We are currently and have been engaged to develop a line of low cost, high performance UAV's (Unmanned Air Vehicle) for test and evaluation purposes capable of lifting payloads ranging in weights from a few ounces up to 200 pounds.

6) As an adjunct to the UAV development, the design and production of a lightweight, low cost modular essential flight instrument/navigation/autopilot/datalink system suitable for UAVs and light manned aircraft.

7) We have developed the concept for, and are in the design phase of a zero-emissions hybrid vehicle power train that balances the strengths and weaknesses of pneumatic- and electric power sources to extend the range and efficiency of the system.

8) Additionally, we have developed and tested, at our facility in the high desert of California at Ridgecrest, a "smart controller" that optimizes the performance of evaporative coolers by balancing fan speeds and fluid flow rates against the real-time environmental factors of temperature and humidity.

9) RFD Control Unit We have developed a RFD (Radio Frequency Distribution) antenna switching control hardware, firmware, control software, and test software to be used in a radio dense environment. This unit is designed to switch radios to specific antennas within the surrogate vehicle. The software for this unit is intended to be installed and operated on a Personal Computer (PC) or Workstation running Windows XP, Windows-7 or Windows 8 operating systems. The software utilizes a single serial data interface between the host computer and a RFD Control Box, which replaces the same function found within the existing customer switching control unit.
