Anti-JACK (Anti Jammer)
Supported model: Gmm-u5j (MT3329)
GPS jammer "detect and report system" integrated into GPS module
Overview
Anti-JACKTM (Anti-Jamming Assessment Command Feedback), is an advanced GPS jammer detect and report system integrated within Gmm-u5j and compatible GPS module. Upon GPS jammer detected, the GPS module will send both a hardware level voltage high signal (for use with security system such as car alarm) and proprietary protocol via UART Tx (for warning via external GSM/GPRS modem).
Background
Even though GPS is depended by millions worldwide for its positioning and timing capabilities, GPS signals, after traveling through 20,000 kilometers of unpredictable atmosphere, are weak and prone to be interrupted by the simplest GPS jammer. With the rapid increase in the availability of low-cost, highly illegal GPS jamming devices, there exists a major security hole that compromises the safety of traceable assets or fleet workers.
Insurance companies around the world have reported a significant drop (up to 20%) in stolen vehicle recovery due to the use of GPS jammers.
GlobalTop Solution
Anti-JACKTM is a powerful, easy to use GPS jammer detection and notification system designed to enhance security with double-layer of protections. Anti-JACK? is able to alert the security system embedded with Gmm-u5j GPS receiver on nearby GPS jammers through its customized NMEA protocol, or via direct voltage level with dedicated hardware pin out. System integrators can transmit the protocol to a cellular radio of his choice to remotely alert users, or have it connect to a physical alarm or siren that blast out loud when the system is tempered with.
Using its special circuitry, Anti-JACKTM is able to provide two levels of jamming sensitivity that can automatically adapt to different antenna setup (active or passive antenna). A total of 4 different GPS jammer detection mode is offered, including a smart power saving mode that reduces power consumption used by jammer detection when the GPS signal reception is above acceptable. Last but not least, all Anti-JACK? settings can be easily toggled with simple packet commands.
Requirement
Anti-JACKTM is a standard feature that comes bundled with Gmm-u5j. Test software is also available for download.
