Zipping across the sky is as warm of satellites that enables global navigation, weather monitoring, and telecommunication. But have you ever wondered how messages travel across the globe in an instant? When a message needs to be sent, it is first transmitted through an uplink channel, which carries it from a ground station to the satellite. Once received by the satellite, the message is then relayed to the next ground station via the downlink channel, completing its journey. Together, these channels allow for seamless and global connectivity bridging the distance between the ground and the sky.
