EarTraX Tags contain many features that make them one of the most advanced wildlife telemetry GPS collars available to purchase at this moment in time. At its simplest, the unit collects GPS data which can be downloaded via a coded UHF telemetry link.
GPS and UHF schedules, received data and diagnostics are all programmable through the UHF link.
All tags provided by GPS Collars Ltd are capable of tracking the fine-scale movements of a variety of animals through many different habitats. Furthermore, by taking advantage of the collar's flexible scheduling option, your study can be customised to your particular research needs.
Based on our field tested and proven design, you can collect up to 512,000 data records depending on battery life.
GPS Collars Ltd offers unlimited customer support and a full one year warranty on all of our equipment. When returned for a battery change, tags are fully serviced and an additional one year warranty is provided.

uBlox GPS receiver: most up to date rceiver speciliased for wildlife tracking
Coded UHF Beacon and Transmission: In USA 916MHz, Rest of World 863-870 MHz: Last recorded GPS location always transmitted within UHF pulse. No need to triangulate. Full data download via UHF.
Up to 512k locations; essentially no limit. Data never lost from unit. Data stored on board for later download thoruhg UHF link. See Tab re Download and Web Access for more information.
The period of inactivtiy which could be interpreted as the death of an animal can be set to any time that is required. When triggered, a text is immediately sent to our servers which is then relayed on to you via email and also sent as a text your mobile phone. The UHF tracking beacon then transmits more frequently, transmitting the last known GPS location.
3D accelerometers record movement in each plane every time a location is recorded. This data can indicate various movements of the animal.
Transmission of GPS Location Data using UHF Beacon/Connection
GPS Data is collected and stored into archive (locally) on board the unit and is extracted upon an explicit command from UHF Link.
Beacon: Every 4.3 seconds, the unit transmits a pulse from the UHF beacon - just like a standard VHF radio tag. The unit can be tracked using the same triangulation methods used for tracking standard VHF tags. However, the unit will also transmit the last recorded GPS location (Lat Long) which is displayed on the hand held receiver.
UHF Comms: Every 10th pulse, the unit adopts a listening mode. If in that time, the unit receives a message from the hand held receiver, then the unit will turn on and transmit all saved data in the archive.
Line of site the beacon and data download will work over 5km and in some cases up to 15-30km.Using the Web Interface
