An optical ground station (OGS) is a vital part of the infrastructure that links space to the ground. The system helps in providing real-time communications for various applications at much higher data rates (up to several Gbps) than RF. The increasing need for higher-resolution data for missions that require scientists to get a detailed look at the Earth and solar system results in the high demand for OGS systems. The system also helps in providing large volumes of data to fulfill mission requirements and locate the ground assets relating to mission orbit parameters. Thus, the demand for OGSs is increasing globally for more accuracy and high-speed data transfer.
Furthermore, the number of satellite launches has increased, and the need for optical ground stations also rose as they are used for commissioning and routine checkout of the satellite and transmitting and receiving the data simultaneously. Moreover, optical ground stations provide real-time communications at much higher data rates, up to several Gbps, compared to RF, which can be used for various applications such as broadband, navigation, and research. In addition, the optical ground station also helps survey space debris in different orbits around the Earth. Also, it is used to conduct surveys and follow-up observations of near-Earth objects, which can help protect the satellites in space and understand the accurate time and place to launch the satellite.
