Software-defined radio (SDR) technology can emulate several subsystems of a small satellite. These subsystems include:

Communication System:

SDR can simulate the communication subsystem, which includes transceivers, antennas, and signal processing components used for transmitting and receiving data between the satellite and ground stations or other satellites.

Navigation and Positioning System:

SDR can emulate the navigation and positioning subsystem, replicating GPS receivers or other navigation sensors that help determine the satellite’s location and orientation in space.

Onboard Data Handling and Processing:

SDR can mimic the onboard data handling and processing subsystem, which involves the satellite’s computers and software responsible for managing and processing data collected by its sensors or payloads.

Power Management System:

SDR can replicate the power management subsystem, including solar panels, batteries, and power distribution systems that provide electrical power to various satellite components.

Thermal Control System:

SDR can emulate the thermal control subsystem, which uses temperature sensors and heaters to regulate the satellite’s temperature and prevent it from overheating or getting too cold.

Attitude Control System:

SDR can simulate the attitude control subsystem, which includes sensors, gyroscopes, and actuators used to control the satellite’s orientation and ensure it points in the desired direction.

Payload and Scientific Instruments:

SDR can also emulate specific payloads or scientific instruments onboard the satellite, depending on the mission’s objectives. This may include sensors, cameras, or scientific instruments used for data collection and research.

SDR technology’s flexibility makes it a valuable tool for testing, developing, and validating the functionality of these subsystems in small satellite missions.
