Navigation Systems
Background:
MnDOT Aeronautics establishes, operates and maintains electronic navigation aids to augment the federal system in Minnesota; installs, maintains and upgrades radio navigational aids such as Very High Frequency Omnidirectional Radio Range (VOR) systems, Distance Measuring Equipment (DME), Non-Directional Beacons, and Instrument Landing Systems (ILS). Technical, planning and financial assistance to publicly-owned airports for airport electrical systems is also available. Examples are upgrading lighting systems, power distribution systems, visual navigation aids, and radio controllers for airport lights.
Aeronautics is also responsible for installing and maintaining Automated Weather Stations Systems (AWOS) at Minnesota public airports and for collecting and disseminating aviation weather information to pilots through use of electronic devices. Click here for a list of AWOS in Minnesota.
For questions and information regarding Minnesota's navigation systems and AWOS contact Bob Milton at 651-234-7250 or bob.milton@state.mn.us.
Wide Area Multilateration (WAM)
The Minnesota Office of Aeronautics wants to fill a large radar coverage gap in Minnesota with a new technology called Wide Area Multilateration (WAM). The project will be 100% State funded through bonding and the State Airports Fund. Although FAA has just begun phase two of a WAM project with Colorado, they favor another technology, Automatic Dependant Surveillance - Broadcast (ADS-B), and will not approve a WAM project in Minnesota.
