Location Finder using IMSI catcher

IMSI catcher or International Mobile Subscriber Identity catcher are the devices used by the defense and law enforcement agencies to track the location of the suspect that is connected to a mobile network, without the knowledge of the service providers and the mobile users.

Let’s begin understanding the working of IMSI catchers:

When a mobile phone is turned on, the device receives signals from nearby network towers. During the call, the base station analyses the position of the phone and determines the nearby base station that can provide the best service.

Once an SDR IMSI catcher system is deployed, the system automatically scans for all active 2G, 3G, 4G, and 5G networks in the regions. Then the system tunes the BTS to the weakest signal available in the region and forces all the mobile devices to connect to it. Finally, the system collects the relevant IMSI, IMEI data for analysis.

We at Sunartek Labs have designed STN-INT-5020 SDR IMSI Catcher to determine IMSI, IMEI identities of 2G, 3G, 4G, and 5G mobile phones.

STN-INT-5020 IMSI Catcher of Sunartek Labs

Sunartek’s SDR IMSI catcher is mainly intended for government and law enforcement agencies. This system gathers IMSI, IMEI identities of the mobiles phones present in the network and can be integrated with a Semi-Active GSM monitoring system to intercept calls and messages.

Working of IMSI Catcher


1. Network Scanning

SDR IMSI catcher system scans and identifies all active 2G, 3G, 4G, and 5G networks present in the region.

2. BTS Creation

The system creates a fake Base and Transceiver Station (BTS) and forces all the mobile devices in the region to register to this BTS.

3. ID Collection

During the process of registration with the BTS, the SDR IMSI catcher system collects the identities such as IMSI, IMEI, and TMSI data from the device. Using these identities, the location of the target can be determined.
Sunartek’s SDR IMSI catcher can either be used as the systems on racks or can be a vehicle-mounted system as per the requirement.

Handheld Direction Finder

GSM direction finder can be deployed with an IMSI catcher to determine the location of the suspect. The user chooses the channel number on the IMSI catcher for paging. And the paging is continued till the location is detected on the direction finder. During paging, the IMSI catcher forces the mobile devices to operate on a fixed channel and the response to the paging will also be sent on the same channel. Using the known channel GSM finder locates the target. The volume level in headphones and the number of segments in the LED are used to determine the direction and distance of the target.

Hence, an IMSI catcher with a direction finder/location finder is an efficient tool to find the location of a person. And is mainly deployed in investigative agencies, defense agencies and police.
