Normally, 3G Vehicle Tracker is Connecting with Car Original Fuel Sensor!
In the following cases, you may want to block the Vehicle GPS Trackers temporarily!
1. Taxi operation management: want to take more distance to earn more money for your family!
2. Rent car management: do not want the car rental company to know your travel trajectory!
3. Vehicle insurance company management: get more free driving time and route, but do not affect your insurance!
At this moment, you want your vehicles or cars be not tracked completely!
Here we analyze the hardware configuration of these GPS TRACKERS.
GPS+GSM Base Station Dual Tracking
GSM Module: SIMCOM800
GPS Module: U-blox 7Q
•GPRS multi-slot class 12/10
•GPRS mobile station class B
•Meet the GSM 2/2 + standard
– Class 4 (2 W @850/900MHz
– Class 1 (1 W @1800/1900MHz)
•FM:band limits 76~109MHz,Tuning step by step50KHz
•Via ATcommand control 3GPP TS 27.007, 27.005 and SIMCOM enhance ATcommand set)
Supply voltage range3.4~4.3v
•Operating temperature range : -40 ~+85 °C
|GPS/QZSS L1 C/A, GLONASS L1 FDMA|
So most of the GPS locators use of GSM + GPS two signals to achieve positioning, when the GPS signal blocked only, GSM / GPRS can also achieve positioning!
So when you buy the GPS jammers, you have to determine what car gps tracker installed!
