The electronic systems and components installed on a launch vehicle that is responsible for its guidance, navigation, control, and communication during all phases of the mission are referred to as launch vehicle avionics. These avionics systems are critical to the successful launch and delivery of payloads to their desired orbits.
Flight computers serve as the avionics system's central processing units, performing computations, executing control algorithms, and coordinating data exchange between different subsystems. They handle tasks such as sensor data processing, trajectory calculations, and actuator control in real-time. GNC systems oversee determining the position, velocity, and attitude of the launch vehicle, as well as controlling its trajectory. They are typically made up of sensors like accelerometers, gyroscopes, and GPS receivers that provide input to navigation algorithms.
To ensure precise trajectory and mission objectives, the GNC system calculates optimal commands for vehicle control, including thrust vector control and steering. During a mission, launch vehicles generate massive amounts of data, including vehicle health status, sensor measurements, and telemetry data. Telemetry systems collect, process, and transmit data from the launch vehicle to the ground control center, allowing for real-time monitoring and analysis of the launch vehicle's performance.

Telemetry systems collect, process, and transmit data from the launch vehicle to the ground control center, allowing for real-time monitoring and analysis of the launch vehicle's performance. Avionics on launch vehicles require a dependable and efficient power supply.
Power distribution and management systems are in charge of distributing electrical power to various subsystems and ensuring that each component receives the proper voltage and current. These systems frequently include backup power sources, voltage regulation, and fault protection mechanisms. Avionics systems use a variety of sensors to collect information about the launch vehicle's performance and the environment. Accelerometers, gyroscopes, altimeters, pressure sensors, temperature sensors, and attitude determination sensors are examples of these sensors. These sensors' data is used for real-time control, monitoring, and safety evaluations. Avionics software consists of embedded software and algorithms that control the launch vehicle's operations, process data, and perform guidance and control functions. To ensure reliability and robustness, software development includes rigorous testing, verification, and validation.
Avionics systems must be seamlessly integrated with the launch vehicle's other subsystems, such as propulsion, structures, and payload systems. To enable data exchange and interoperability between avionics and other components, interface standards and protocols are established.
