RF GPS Tracker

RF GPS Tracker

The RF GPS tracker allows users knowexactly where they are and their group members are at any time. The position ofthe target person can be displayed on a screen. With a built-in E-compass, theGPS tracking unit allows users know the direction when get lost. Due to these,the product is ideal for use when users are attending outdoor sports andadventures, like hunting, go fishing, go boating, surfing, skiing,and so on. Also,it can be utilized in tourism, trackingpets, monitoring students by schools when organize outdoor activities, criminalinvestigation for tracking criminals and suspects, anti-theft and tracking foroutdoor mechanical equipment, etc. In addition, in the near future, theRF GPS tracker may also be used by policeman to work as a walkie-talkiedevice.

Please note that the RF GPS tracker should be used as a complete set whichincludes two parts. One is the Master to offer monitoring function and theother is Slaves to be tracked. One Master is able to monitor at most 50 Slavesor communicate with at most 10 Masters. Two main modules are built in the twodevices. One is GPS module s used for positioning and the other is radio moduleutilized for communicationbetween masters and slaves/masters.

Unlike a GSM tracker or GPS tracker, our RF GPS tracker requires no SIM card orGSM and GPRS service fees.


Main functions (Master to Slaves)
1. Positioning
Due to thebuilt-in GPS module inside of Slaves, it is easy for the RF GPS tracker to getthe position of Slaves.

2. Gather their slaves
The master can gather at most 50 slavesand get their directions and the locations shown via longitude and latitude.

3. Data logger function
The master can record the slave’s history, and replay it. 

4. SOS Emergency help
There’s SOS keypad on the RF GPS tracker, so the user can press the key tosend SOS alarms.

5. Geo-Fence (Park) Function
This function limits the target within a circle with semidiameter of 800m. When the target runs out of the range, theMaster will send alarms.

6. Report location
Due to the built-in radio module, the GPS tracking unit can send theSlaves’ position information to the Master. Currently, the maximum range is 3KM, and it will be 5KM in the future.

7. Save power
The Slaves come into sleep mode when GPS signal is unavailable, and restartautomatically when GPS signal is gained.


Main functions (Master to Master)
1. Positioning
Built-in GPS module inside of the Master allow users to get the position ofall Masters conveniently.

2. E-compass function
The built-in E-compass module in each Master enables users to get thedirection at any time. That is, with the RF GPS tracker, users never need toworry about getting lost.

3. SOS Emergency help
The SOS keypad allows users to send emergency alarms via pressing the key.

4. Geo-Fence (Park) Function
The geo-fence range is a circle with a semidiameter of 800m. When the target runs out of the range,the Master will send alarms.

5. Gather masters
The Master is able to communication with 10 masters and get their directions. The locations are shown via longitude and latitude.

6. Data logger function
One Master can record the other Master’s history, and replay it.

7. Walkie talkie (future function)
One Master user is able to talk with at most other ten Master users.

The above is the schematic drawing to show the main function of our RF GPStrackers.
