Problem statement. A promising direction for the development of the global navigation satellite system is the creation of new types of signals with code separation. High availability and accuracy of consumer location determination refer to signals having an autocorrelation function with a narrow main peak and a low level of side lobes. One of the types of such signals is promising multiplexed TMBOC signals. But the processing of this signal has not been fully studied, namely, signal processing with TMBOC modulation in an incoherent reception mode.

Purpose. Synthesis of an algorithm for incoherent reception and processing of a multiplexed TMBOC signal at a single intermediate frequency.

Results. Analytical expressions are obtained for the output voltages of the discriminators of the frequency tracking system and the delay tracking system. The schemes of discriminators of the frequency tracking system and the delay tracking system are obtained.

Practical significance. The results can be used by specialists in the field of satellite radio navigation in the modernization of global navigation satellite systems.
