Satellite Tracking of Animals

Have you ever wondered how satellites can track birds, fish and other animals?
They use  dedicated satellite systems and tiny lightweight transmitters that send signals to polar orbiting satellites. The high speed of the satellites causes a Doppler shift as the satellite passes overhead in its low polar orbit.

Here are some websites to help your research.
