The time-reference scanning-beam microwave landing system (TRSB MLS) is a system approach to the landing-guidance problem--it can meet a wide variety of diverse performance, economic, and safety requirements and still supply a universal airborne receiver-processor able to operate with all ground systems. The TRSB is an "air derived" system operating in the C-band. Ground-based equipment supplies signals to a receiver in the landing aircraft to determine position information: two angle coordinates and a range coordinate. The angle information is derived by measuring the time difference between the successive passes of highly directive, narrow fan beams. One beam scans in azimuth and one in elevation. The range information is derived from equipment similar to conventional L-band distance-measuring equipment (DME) modified for additional precision.
