SNR

SNR stands for Signal-to-Noise Ratio, which is a measure of the strength of a signal relative to the background noise. In space and astronautical engineering, SNR is an important parameter for communication systems, as it determines the quality of the received signal. A higher SNR indicates a stronger signal and better communication quality, while a lower SNR indicates a weaker signal and poorer communication quality. SNR can be improved by increasing the signal power or reducing the noise level. In space applications, SNR is particularly important for deep space communication, where the signal strength is very weak due to the long distance from Earth. In such cases, specialized antennas and signal processing techniques are used to improve the SNR and enable reliable communication.
