MITAS

The Worlds First PC Based Wildlife Telemetry Receiver!

  

MITAS revolutionized wildlife telemetry. As major projects were initiated in the Columbia River Basin to study the dwindling salmon stocks, conventional receivers became awkward to manage. MITAS combined the functionality of several receivers into a single PC based system capable of displaying activity in real time in several different formats. The collection of data became as easy as burning a file onto a disk or having the system automatically FTP it overnight. MITAS was the first system to automatically monitor its own status and report it to researchers.

Features:

  • 149MHz to 170MHz
  • 25 Channels
  • Code or Beeper Detection
  • Multiple Code Protocols
  • -105dBm sensitivity
  • 50 Antennas
  • Real Time Displays
  • Auto FTP Upload of Data
  • Auto Email Reporting
