Satellite telemetry is an incredibly powerful research tool for tracking animal movements.  By capturing an animal and fitting it with a PTT (platform transmitter terminal), it is possible to monitor the movements of that individual for a period of months or even years, without ever needing to have contact with the animal again.  This technology has made it possible to research the movements of many species which were previously impossible to track in any detail.

For those interested in the technical aspects of how satellite telemetry functions, a very informative summary on location determination by Fancy et al. is available online at the United States Geological Service.  Another great reference is the Argos Inc. web page, which describes the satellite network in use.  Additional details about satellite telemetry will be discussed within the context of MRF research programs utilizing this method, including Peregrine Falcon and Short-eared Owl studies.
