CellTraX collars 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 and then transmits that data via the GSM cell-phone network to our servers and which is then available to view/download by you, either on a PC or smart phone. Additionally, data can be downloaded via a coded UHF telemetry link.

At the moment, CellTraX Collars are programmable by staff at GPS Collars. GPS, GSM and UHF schedules, received data and diagnostics are all programmable.

Achieve near to real-time GPS monitoring of all your animals.  As a result, all collars 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, collars are fully serviced and an additional one year warranty is provided.

Hardware

uBlox GPS receiver: most up to date rceiver speciliased for wildlife tracking

Quad and Penta band mobile phone engine: Works in every corner of the world where GSM services are available.

Coded UHF Beacon and Transmission: In USA 916MHz, Rest of World 863-870 MHz:  Last recorded GPS location always transmitted within coded UHF pulse. No need to triangulate.

 

Memory

Up to 512k locations; essentially no limit. Data never lost from unit. Data transmitted to our servers and also stored on board for later download. See Tab re Download and Web Access for more information. 

 

Mortality

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.

 

Activity

3D accelerometers record movement in each plane every time a location is recorded.  This data can indicate varius movements of the animal. 

 

GeoFence

Enter coordinates of your study area.  If the animal goes beyond that boundary an alert is sent to you via email and text.

 

Transmission of GPS Location Data using GSM Connection

Data sent from Buffer:  GPS Data is collected and stored into buffer (in addition to storing to archive) ready to be sent upon next GSM 3G or 4G connection.

Data sent from Archive:  GPS Data is collected and stored into archive (locally) on board the unit and is extracted upon an explicit command from our servers. GPS data to be stored into archive can be collected more frequently than GPS data stored into buffer. The interval between successive GPS location points stored into archive and successive GPS location points stored into buffer can be different. GPS power drain is extremely small while GSM power drain is very high particularly where 3G and 4G signals are poor.  Therefore, in poor GSM areas, we can set the archive GPS data to a high rate - 15 minutes for example, while the GPS data to buffer can be far lower - 4 hours for example.  When the unit connects in poor service areas, then only a small packet of data is sent from the buffer which is more likely to be successful.  When the unit comes into a better service area, we can then request to download all the data out of archive.

All data downloaded via 3G/4G are included within the monthly airtime costs.

Data sent Immediately:  GPS Location Data is collected (stored into archive and buffer) and is sent immediately by SMS text. Sending data via SMS text in this manner will incur additional charges and is outside the scope of the monthly airtime costs.

 

Transmission of GPS Location Data using UHF Beacon/Connection

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.
