GPS collar tracking system helps understand the wildlife migration habits

Lynx GPS trackingNature scientists have tracked the movements of wild animals with electronic collars that emit radio signals in the VHF band. The data received from the collars helps researchers to better understand the animal's social structure, mortality rates, feeding ecology and other behavior patterns. That method of  tracking wild animals requires ecologists work extensively in the field to search for the radio signal from the collars, then record the wild animals location on a handheld GPS, which is a cumbersome process. The new generation of GPS collars is designed to calculate the exact location of the wild animals with adjustable polling intervals from seconds to hours and send a data packets and text messages to a central processing application via the first tier of the distributed GPS tracking system which consists of multiple VHF transmitting GPS enabled tracking collars. In many cases the researchers use custom built expensive GPS tracking collars for larger animals, but often the less expensive GPS tracking systems such as Astro DC 40 or DC 30 transmitters and and Astro 320 receivers could be used at a fraction of cost. The collars are instantly paired with GPS navigation handheld receivers either Astro 220 or Astro 320 among most advanced models. Originally designed as hunting dog collars the Dc 30 and Dc 40 have been proven to be suitable not only for dogs but for many other animals including wild cats, mountain lions as one example. GPS tracking collar helps researchers bring to light critical information about pumas and mountain wild cats as many regions most active predator, so that key conservation objectives can be initiated to preserve this essential member of the ecological environments. Biologists have collared growing numbers of wild animals for tracking in studies to better understand the migration habits of wildlife across geographical areas. Lynx, pumas and mountain wild cats have been fitted with innovative GPS tracker collars with an embedded accelerometer to provide new insight into puma wildlife range, habitat, biology and behavior. 

GPS tracking device for PumaDepending on the goals of the wildlife research the GPS navigation and tracker system may take shape of a complex multi-tiered distributed platform. The Astro 320 combo bundle of the navigation handheld and DC 40 tracking GPS collar is a good example of the first tier at the heart of the more complex wildlife animals tracking system. Both the collar and the host station are receiving the GPS satellite constellation information in real time. Multiple Astro units are individually paired and work as universal VHF radio communication devices with collars transmitting the tracked animal's most current GPS location Astro 320 host device which compares the received GPS location information with its own reading of the GPS satellite constellation. Next tier of distributed application may perform the consolidation of information from GPS navigators and involves a cloud computing web services enabled dedicated servers, which are collecting information from GPS devices and store in the database. The processing application queries the data cube, extracting records containing most current information about animal's location, and then translates it into an electronic messages for the distribution to the subscribed researchers and to the e-mail web service application. In parallel, the data then is analyzed, formatted and aggregated on an open-source topographic map that displays the wild animals' movements, allowing nature researchers to know when the animals have strayed too close to livestock herds. The GPS tracking collar advanced antenna design safeguards against the animal location information is getting lost when the animal enters into the water to cross the river.  Astro DC 40 is rugged and reliably works in all weather conditions.

Astro 320 DC 40 collar tracking systemCombination of a high-sensitivity GPS collar receiver, quad helix GPS antenna and extended range VHF antenna into an all-in-one transmitter makes this orange colored collar the universal wearable tracking device eliminating the need to put two separate collars on an animal. Each collar transmitting circuitry has an unique electronic lock which uses a four-digit PIN number that helps keep the data packets broadcast by the collar secured in transmit. The paired Astro 320 navigator unlocks the information for the nature scientists to see  tracked animal  whereabouts. The GPS satellite acquisition system keeps connectivity with the GPS constellation satellites even in the  heavy bush or densest covered forest. The DC 40, in combination with the Astro 320 pinpoints the tracked animal position in preselected intervals to keep optimal balance between frequency of the transmit intervals while checking the animal current location and longer battery life. With an increased range and simplified user interface the Astro also offers rich mapping capabilities.

Depending on terrain Astro 320 keeps track of up to ten animals as far as nine miles away.  Animals that are too far away to fit on the Astro 320 map’s current zoom scale can be notated on the display’s margin in the direction of the animal’s location. The researcher also can choose the duration that each animal’s track-log is viewed on the display, and optionally completely toggle it off for a cleaner display. The nature animal scientist or nature explorer can mark the exact spot - a special waypoint that will keep the exact location, time of day and elevation where the animal performed certain activity such as has found its prey. The tracker page allows to view a compass pointing to most current animal location. Astro tracking system lets the researcher save other special waypoints, such as location of the vehicle and base camp for each trip in the field.

The mode of operation of the dog GPS varies as the types. Most trackers use rechargeable battery. In some types, alerts from the collar are received via e-mail; fax or GSM while there are modern once that have alert receiving device held by the owner.

great gift ideas
