About Tracking with GPS or Argos

One of the most effective ways to track an animal in the wild is to equip it with a GPS, ArgosTrack or GPS Argos wildlife collar. Using the Navstar Global Positioning System (GPS), a constellation of 24 satellites that orbit the earth and transmit navigational data, the Lotek GPS collars provide an accurate means of monitoring animal movements through a variety of terrains and climates. Similarly, our ArgosTrack collars take advantage of the Argos system's array of satellites to transmit and obtain positional data on animals equipped with the collars.


Lotek GPS collars contain the following:

  • GPS receiver
  • VHF tracking beacon
  • computer/memory module
  • radio modem (GPS 4400)

ArgosTrack collars can be equipped with:

  • ArgosTrack PTT
  • VHF tracking beacon
  • Drop off
  • Temperature sensor
  • Activity sensor

Types & Options

Lotek offers a choice of GPS collars: the GPS 3300 for small and midsize mammals, and the GPS 4400, GPS 7000, and GPS 8000 for midsize and large mammals.

We offer two types of Argos collars: ArgosTrack are typical Argos positioning transmitters, whereas GPS Argos are GPS dataloggers which transmit GPS locations through the Argos system.


Lotek was the first in the world to introduce GPS for wildlife research. Since we introduced the GPS_1000 in 1994, we have added a number of innovations to this product line, including:

  • remote two-way communication, which allows you to retrieve data on demand and/or reprogram the collar while it is still on the animal
  • temperature and mortality sensors
  • VHF tracking beacon
  • user-programmable scheduler
  • field uploads & downloads
  • differential GPS accuracy

More complete lists of GPS features and innovations can be found through links within the pages devoted to the GPS 3300, GPS 4400, GPS 7000, GPS 8000, and ArgosTrack & GPS Argos.

Species & Habitats

The GPS 4400 collars can be used on a variety of midsize and large mammals including caribou, moose and elephants. The GPS 3300 can be deployed on animals as small as roe deer, coyotes, bobcats, wolves, bears, large cats and deer. Our Argos collars can also be used on animals such as moose, wolf, deer and bear, to name but a few. GPS and Argos tracking can be done in almost any terrestrial habitat.


To give just a few examples, our satellite collars have been used in habitat analyses of:

  • moose in northern Ontario and Sweden
  • caribou in Québec and British Columbia
  • red deer in France
  • elephants in Kenya
  • plains bison in Saskatchewan
