GPS Plus collar line                           NEW: store on board collar for 1250 Euro      

The GPS collar can store the positions of the animal on board on a nonvolatile flash memory. For all possibilities of remote fix data download see: overview.

The basic is the GPS Plus collar. There is a wide range of GPS collars available with weight up from 350 g, suitable for different neck sizes and animal weights. The number of fixings is estimated for “worst case scenario” and “average scenario”.  Worst case scenario means the GPS receiver needs 3 minutes  in the mean for a location fix estimation, average scenario means the receiver needs in the mean 90 seconds  for a fix estimation. Operational lifetime of GPS collars is represented in table 1.

The collars can be fitted out with different accessories.

 

This is a selection of GPS Plus collar features:

  • The GPS collar fixing scheduler is user programmable.
  • All antennas are integrated in the collar belts, there are no external wires.
  • GPS collar battery packs can be replaced easyly in the field.
  • Operating temperature range: -50 °C to +50 °C.
  • Software interfaces: based on windows 95 or higher, the software is free of charge.

Some more imagines of older GPS collars

A wide range of  configurations are available to address your satellite tracking needs. The system design most suitable for your particular study is dependent upon an equally wide range of application specific factors. The GPS collar is suitable for wildlife tracking (herbivorous, predator) as well as for domestic animals like cattle etc..

The weight of the collar is mainly due to the weight of the batteries along with the other hardware components (collar material, castings, etc.). The GPS-receiver only weighs 5 – 10 g. The number of batteries needed depends on the capacity and the electricity consumption of the electronic systems whereby the GPS-receiver alone uses 95%. 

The electricity consumption of the GPS-receivers depends on how much time is required to determine a position and how much time is maximally allotted for this (“GPS on time”). For a valid 2D localization the signals of at least 3 satellites, for a 3D localization the signals of at least 4 satellites must be simultaneously received. Depending on the external conditions (terrain topography, shading of the GPS-collar by dense vegetation, for ex.,) a great amount of time may elapse. Subsequently, the system goes into a very low energy use phase until the next position can be ascertained. If the positions are recorded at close intervals, the next localization is completed more quickly than with long intervals because the GPS-receiver needs less time to renew its information from the satellite.

In order to compare the capacities of different GPS-collars, the position calculation method the producer uses must be known, especially what time period is allotted for the “GPS on time” (common value = 90 sec). Then it is important to know whether the number of localizations were calculated according to a “worst case calculation”, i.e. whether the number given corresponds to that which the GPS-receiver can achieve at defined conditions (for ex., 0°C ambient temperature); or whether the calculations were done for optimal conditions giving the maximum number of positions.

The outried from the collar or download data are easilye transferred to a geographical information system with thematic maps. Table 2 shows a typical data set from a GPS- Plus collar.
