The development of deposits in the Far North is one of the global projects implemented by the Russian Federation. Effective control and monitoring of the condition of unattended objects (UO) engaged in hydrocarbon fishing, reliable communication of control commands to them is possible only with the help of low-orbit satellites (LOS) combined into one grouping. However, as the number of countries involved in the development of deposits in the Far North expands, the number of LOS groupings will also grow. As a result, the receiver located on the UO will see several repeater satellites at once. In this case, a low-orbit intruder satellite (LOIS) may try to impose a previously intercepted control command on the receiver, which may lead to the failure of the UO. To prevent the possibility of imposing such spoofing interference, you can use the low-orbit satellite identification system (LSIS). The effectiveness of the LSIS depends largely on the identification protocol. In order to increase the speed of authentication of the NS, in a number of works it is proposed to use a zero-knowledge protocol, which is performed in modular codes (MC). This result is achieved by parallel execution of arithmetic operations on the basis of the code. However, this property of the MC can be used to increase the noise immunity of the LSIS, which must function in various weather conditions. The goal is to develop a noise-resistant protocol for recognizing an LOSrepeater, executed in modular code and requiring less time for error correction
