Aviation Spectrum Resources, Inc.

Aviation Spectrum Resources Inc, or ASRI, is based in Annapolis, Maryland. It manages radio communication licensing for the aviation industry in the United States and its territories. The site says the company is owned by the aviation users of the United States.

ASRI manages the Aeronautical Enroute VHF spectrum and the Long Distance Operational Control HF spectrum. The site says these are used by aircraft operators and controllers for the safety and regularity of flight.

The company's AGSA service assigns frequencies for aviation business purposes. Customers need FCC approved radio equipment. The site says ASRI helps with new frequency assignments, changes and license renewals.

The site gives two figures for ground radio stations. One says over 5,000 ground stations, and another says over 6,000 licenses. It says ASRI performs 1,000 radio station inspections a year to check compliance with FCC rules.

ASRI is the ICAO registrar for all SELCAL codes. SELCAL is a radio calling system used by ground station operators to contact aircraft. The site says the SELCAL database holds more than 30,000 assignments.

The site says ASRI supports the Aeronautical Frequency Committee, an industry committee. It says ASRI represents aviation positions at ITU and ICAO spectrum committees. It also works with the FCC and FAA on U.S. positions for World Radio Conference meetings.

The company is at 180 Admiral Cochrane Drive, Suite 300, Annapolis, MD 21401. The phone number is +1-410-266-6030. The site lists forms for interference reports, frequency requests, and decommission requests.
