Key Features

  • All positions determined and sensor data collected is stored-on-board the unit, but not transmitted.
  • In addition to the GPS portion of these models, they include a VHF transmitter, which can be used to locate or monitor the animals from the ground or aircraft, and aid in recovery of the unit at the end of a study.
  • These models can include mortality, activity, and temperature sensors.
  • Telonics QFP positioning can be incorporated into these collars. QFP is Telonics quick fix positioning technology that obtains the data necessary to calculate a GPS position in as little as 3-5 seconds. This allows positions to be determined much more quickly and with less energy expenditure than a standard GPS position. Units can be configured to collect GPS, QFP, or a mix of the two location types.
  • All these models are fully-hermetically sealed for maximum reliability, with the transmitter, battery, and interconnects sealed into a single metal housing. This is the same technology used by NASA for maintaining high performance electronics in harsh environments. With hermetic packaging, there is no problem with moisture penetration even after years of deployment, except in cases of severe physical damage to the canister. No polymeric packaging offers this level of reliability.
  • These models can be provided with the GPS antenna end-mounted on the housing (thus side-looking under the animal’s neck) or dorsally-mounted on the collar. Side-mounting is the most durable; dorsal mounts can provide improved GPS connectivity. Dorsally-mounted antennas add somewhat to the weights listed.
  • Telonics CR-2a, CR-5, or CR-7 programmable collar release mechanisms can be added to collars of appropriate size (the CR-2a and CR-5 require at least a 2-inch wide collar and the CR-7 requires at least a 1.5-inch wide collar).
  • Users can program or reprogram these units through use of Telonics Product Programmer (TPP). TPP can be used to obtain estimates of battery life.
  • GPS/QFP collection schedules, VHF schedules, and sensor options can all be user-defined. Scheduling can be programmed to change over time (e.g. seasonal changes where monitoring might be more or less intensive at certain times of the year).
  • Data downloaded from a collar in hand are processed using Telonics Data Converter (TDC).
  • A real-time clock and calendar controls all timing functions and is re-synchronized with GPS time to assure high accuracy timing. All timing is programmed using Coordinated Universal Time (UTC).
  • When turned off using a magnetic switch, these units consume less than 10 µA; this allows storage for extended periods with minimal impact on operational life.
  • Units can be refurbished to their original condition at Telonics.
