Last updated: October 2026
Key Features
Represents the satellite, ground station, transmitting antenna and receiving antenna
Shows the uplink signal from the transmitting station to the satellite
Shows the downlink signal from the satellite to a receiving station
Helps explain how satellites relay data, voice, television, internet and navigation signals
About This Product
Teachers trace the uplink from the transmitting ground station to the satellite, explain how the satellite receives the signal and relays it onward, and then follow the downlink to the receiving station. The model supports lessons on space science, radio waves, broadcasting, navigation and communication technology in physics, geography and electronics classes.
Frequently Asked Questions
Q1. What is the difference between uplink and downlink on this model? The uplink is the path from the transmitting ground station up to the satellite. The downlink is the path from the satellite down to the receiving ground station.
