Radiometrics Corporation

Atmopsheric Systems Corporation (ASC) was acquired by Radiometrics Corporation (www.radiometrics.com) in April, 2016. Radiometrics was established for the design, manufacture, sales and use of surface based atmospheric remote sensing instruments and systems to monitor the atmospheric boundary layer parameters such as wind, turbulence and temperature profiles.

Below is a timeline that captures the progression of the company and milestones in its research, innovation, and design of sodar technology.

ASC History

  • 1972

    AeroVironment designs the Acoustic Radar. This design laid the foundation for the high resolution Digital Facsimile display incorporated in the ASC products.
  • 1976

    Xontec enters the world of SoDAR by designing a Bistatic SodDAR system.
  • 1976

    AeroVironment, with support from participants Melborne, designs a monostatic SoDAR which provided the basis for the modern day Model 2000.
  • 1979

    The EPA invites both Xontec and AeroVironment to participate in an intercomparison. This study results measurable correlations and paves the way for another study in 1982.
  • 1982

    Xontec and AeroVironment participated in another intercomparison sponsored by the EPA again proving the technology. This study results in EPA sign off on SoDAR as an acceptable monitoring device that meets the EPA criteria.
  • 1982

    Dr. Underwood, after completing his PhD on SoDAR and teaching at Florida State University, joins Xontec to work with the Xondar, Xontec�s existing SoDAR.
  • 1982

    Dr. Underwood designs the revolutionary phased array antenna (this design has been implement in the ASC 3000 and 4000 products and mimicked by other SoDAR manufacturers). Dr. Underwood also designs the 1st PC based signal processor for the SoDAR application.
  • 1988

    Dr. Underwood joins Aerovironment Inc.
  • 1990

    AeroVironment purchases the Xondar product lines (phased array and Bistatic) from Xontec.
  • 1990

    NAVY SBIR project begins.
  • 1992

    The miniSoDAR (Model 4000) product line is developed through the efforts of the SBIR grant resulting in a successful commercialization of the system.
  • 1994

    Aerovironment sells the 1st Network of miniSoDARs (Model 4000 product line) systems to Berkley Network Labs for emergency response purposes. These units were in operation for over 12 years.
  • 1994

    SodarPro and PADS data products are developed allowing for real-time data streaming and data storage in a database.
  • 1997

    The 3000 Hz phased array SoDAR is completed (Model 3000)
  • 1998-9

    The Range Standardization and Modernization program results in the sale of 14 systems (8 to Cape Canaveral and 6 to Vandenberg). This program requires a minimum 15 year enclosure lifetime resulting in the fiberglass enclosures still in use today. These enclosures provide a 20 year life expectancy.
  • 2002

    AeroVironment develops the 1st solar charged, battery powered SoDAR. This system is also made portable by mounting it on a trailer.
  • 2003

    SodarPro and PADS data products are developed allowing for real-time data streaming and data storage in a database.AeroVironment develops the acoustic refractive index for laser propagation studies.
  • 2005

    Atmopsheric Systems Corporation (ASC) is started when Dr. Underwood (Director at AV) purchases the SoDAR product lines and rights.
  • 2007

    The WindExplorer is born. This self operated system utilizes both solar and generator power sources (as needed) while detecting rain, snow, and operating a heater.
  • 2007

    ASC develops a new signal processing system that allows for the implementation of an easy to use LCD interface.
  • 2008

    ASC and Globalstar join forces to offer satellite data transmission of system data.
  • 2009

    ASC and Digi International reach an agreement for ASC to provide Digi cellular products.
  • 2009

    Complete real-time diagnostics of the entire SoDAR including individual speaker monitoring is finished. This enables users to easily see all systems statuses from any where in the world.
  • 2009

    ASC widens its distribution network reaching agreements with companies in Australia, Argentina, Chile, and several locations within the United States.
  • 2016

    Radiometrics Corporation (www.radiometrics.com) acquires Atmospheric Systems Corporation. Primary operations are now out of Boulder, CO.
