Problem statement. The onboard time and frequency standard synchronizes the onboard equipment, time-stamps data, and controls the exchange of service information as part of the radar system. The overall accuracy of the onboard time and frequency standard and the entire radar system is directly affected by parameters such as absolute error, stability, and discreteness of time stamp readings. Given the restrictions on the use of imported electronic components, it is necessary to create an onboard time and frequency standard based on domestic electronic components.

Goal. Creation of a mock-up of the onboard time and frequency standard unit using domestically produced electronic components.

Result. A project has been developed in the Quartus II software environment to replace imported FPGAs with a domestically produced base matrix crystal. A mock-up of the onboard time and frequency standard unit has been proposed using domestically produced electronic components to obtain synchronized, highly stable time stamps and frequency signals in space-separated onboard devices for various purposes. The main characteristics of the domestic-made electronic component base used in the node layout are presented. The article discusses the algorithm of operation of the onboard time and frequency standard node layout and provides a description of a project for obtaining highly stable time stamps, which was implemented in the Quartus II software environment in order to replace imported FPGAs. A program for checking the specified characteristics of the node is presented, and the specified technical requirements are confirmed.

Practical significance. The presented results confirm the possibility of replacing the imported electronic component base with the domestic electronic component base in the onboard time and frequency standard node. The results of this work can be used in the aviation and space industries.
