Abstract : This report contains the description and results of an Omega/VLF flight program conducted in the continental United States (CONUS). The data collection period was during May 1983. The purpose of the program was to collect Omega and VLF signal coverage and accuracy data representative of low altitude, low speed operations typical of helicopters and general aviation aircraft. The aircraft used was a Beechcraft Queen Air, Model 65. The aircraft was configured with a data collection palate and multipin electrical connectors located in the aircraft cabin. An ARINC 599 type Omega/VLF navigation receiver was used in the project. A flat plate, E-field antenna was mounted in the bottom of the fuselage near the empennage. A microprocessor controlled data collection system, utilizing a scanning DME and other aircraft navigation instruments, was used to record data and establish aircraft reference position. Route segments, totaling over 7000 nm covering much of CONUS, were flown during the project. Data were recorded on all route segments. Over 7000 data points were used in the accuracy analysis.
