Radio TrackingRadio collars transmit radio waves of a specific frequency at a rate of approximately one signal per minute (can be varied). A directional antennae and receiver are needed in order to pick up the transmitted signal. This equipment can either be hand held as the biologist walks or drives slowly through the area, or it can be mounted on the wings of a plane. A very accurate location of the collared animal can then be determined by a field triangulation method which requires the use of GPS locates, compass directions and maps. (Next Brady - show the following pictures: radio collar, directional antennae, receiver, entire telemetry set) At the bottom of this page I would like this: Excellent resources on radio telemetry: Handbook of Animal Radio-Tracking; University of Minnesota Press - written by L. David Mech (LINK HERE TO MECH"S WEB PAGE ALSO) ATS (Advanced Telemetry Systems) (LINK HERE TO ATS document - I will resend this and label it as ATS document so you know what I am referring to) |
