Abstract:	The basic work of designing and establishing System of Radio Navigation for aircraft has the so-called Polar Coordinate or Rho Theta been accomplished. Through the RTCA coordinating facilities the details of this system have been worked out to the satisfaction of all users. The system is now being installed and will shortly come into primary use in the U.S. Of the two elements of the system, the theta, or azimuth, equipment is leading in its practical application; over 250 stations throughout the United States are now commissioned and operating. The Rho, or distance, equipment is being purchased and will lag the theta component in practical use by about three years. Both are, of course, being installed at the same navigation reference points, which dot the country in a grid-like system.
