NG ocean-patrol aircraft, new OMEGA radio navigation gear, and a new ARAR 12 radar and radio location ( " electronic support measures / ESM " ) system.

New radio location systems provided navigation information which could be used to control an autopilot pre-set to fly a specific course rather than to simply maintain the present altitude and heading.

Second, locating the transmitter's position is usually part of SIGINT . Triangulation and more sophisticated radio location techniques, such as time of arrival methods, require multiple receiving points at different locations.

Data was held at a number of sources, and doubts about completeness or consistency of standards led to a remapping project coordinated by Steve Worthington and supported by cave radio location work by Ian Drummond.

In August 1939, it made a flight near the coastline of Great Britain in an attempt to determine whether the 100-metre towers erected from Portsmouth to Scapa Flow were used for aircraft radio location.

Engineers at the PVO came up with the concept of " radiolokatory " ( radio location ) for extending the reconnaissance range, and Oshchepkov was assigned to prepare a paper for the Defense Commissar, asking that a special research unit be set up for a " razvedyvlatl naya elektromagnitnaya stantsiya " ( reconnaissance electromagnetic station ).
