description: Application of low-orbit satellites for automatic ship identification system. The paper describes the principle of operation of AIS. The problem of insuffi-cient efficiency of satellite AIS and the presence of a high probability of collisions during the transmission of messages was found. The object of the study is the appearance of message collisions in the satellite AIS. To solve the identified problem, the method of processing signals on Board the spacecraft was used as the most effective of all the considered options for reducing collisions. The purpose of this work is to increase the level of initialization of ships in the system with AIS based on the use of signal processing received from sea vessels using Doppler filtering directly on the spacecraft. A calculation was performed that provides the efficiency of the signal processing method using a Doppler filter, which showed the result of increasing the detection of ships up to 4 times. However, this method does not make global changes to the AIS system. Proposals have been prepared for conducting a space experiment based on the "Polymorph" multi-purpose platform synergy. The location of the test, the method of controlling the onboard equipment, and the software for processing the received data on the ground were selected. Options for magnetic orientation of nanosatellites are considered and the optimal option for use in CubeSAT satellites is selected.
