| Doppler effect |
Apparent frequency change of waves which results when the source and recipient of the waves move toward, and then away, from each other. A shift in frequency caused by satellite movement toward or away from your location. When the satellite is coming toward you, the Doppler shift decreases the frequency. When the satellite is going away from you, the frequency increases. Like the waves from the ocean piling up in front of a storm.
