Missile telemetry system design and performance analysis

Telemetry is either wired or wireless remote monitoring or control of a system. It is also used in the sense of 'receiving remote measurement' as a word meaning. Thanks to the telemetry system, various data belonging to a system are collected from a certain distance and this data is transmitted to a point to be displayed. Telemetry system is used in many application areas. Within the scope of this study, the focus is on the missile telemetry system. During the development phase of the missiles, various External Store Certification tests are carried out. These tests are very important for collecting data and determining the working limits for the design of the weapon system and its subcomponents under development. The more ground and flight tests performed, the more accurately the design works. A telemetry system is needed at the stage of collecting this data. Thanks to the test head part placed instead of the warhead, data is collected from the electronic card and various sensors in the missile. In this study, the missile telemetry system design and the Telemetry System Performance Calculator Interface program developed in line with this design are emphasized. Thanks to this interface, Link Margin of the Signal to Noise Ratio value is calculated by taking into account the Radio Frequency communication values used in the telemetry system on both the transmitting and receiving sides and the modulation types. According to these modulation types, telemetry communication performances are compared. As a result of the study, Link Margin of the Signal to Noise Ratio in Binary Phase Shift Keying and Quadrature Phase Shift Keying modulations are better than other modulations. As a result of these studies, we provide a more reliable environment for pre-flight by pre-determining the communication parameters of the telemetry equipment required for missile telemetry system design.
