INTERPROBE places significant resources in obtaining the most modern equipment to achieve the ultimate effectiveness in surveillance. Vehicle and personal tracking systems are a large part of this and are constantly under development to improve performance. Global Positioning Satellite (GPS) and Doppler-Based vehicle tracking systems are used in many of our surveillance operations. Various types of systems are available. The type of system used is determined by the circumstances of the surveillance. The following is a general description of the systems that we have available:

SATRAK 1: 30-Day Rental

SATRAK 1: 30-Day Rental The SatTrak 1 is a real-time positioning system. This means that once this unit is installed on a target's vehicle, it is possible for us to track the vehicle's location to its exact position anywhere in the United States. Details Access: Access to the vehicle for a two-hour period is required to perform the installation. When possible, the vehicle is generally brought to the INTERPROBE office by the client. However, when necessary, installations can take place virtually anywhere, at any time. Stealth Level: This system is buried deep inside the body of the vehicle. Finding it would take considerable effort and require some disassembly of the vehicle. Operation: This unit is either used in tandem with physical surveillance or independently. When used independently, the client can randomly contact the Vehicle Monitoring Station at our office at anytime, and the vehicle's location can be provided. At that time, a decision is made as to whether or not to dispatch an investigator to the location, based on the vehicle position.

SATRAK 2: 1-Day Rental

SATRAK 2: 1-Day Rental The SatTrak 2 is a real-time positioning system. It is generally used when the client does not have access to the vehicle and a real-time location is essential. Details Access: Access to the vehicle is not required. Installation is performed in about 10 seconds. Stealth Level: This system is small and hidden on the underside vehicle. It will not be found unless a thorough search of the undercarriage is made. Operation: This unit is generally used in tandem with physical surveillance, but can be used independently. When used independently, the client can randomly contact the Vehicle Monitoring Station at our office and, the vehicle's location can be provided.

SATRAK 3: 7-Day Rental

SATRAK 3: 7-Day Rental The SatTrak 3 is a position recording system. It does not provide real-time information. It is designed to provide a history (in spreadsheet format) of the vehicle's locations over a seven-day period. It is generally used when the client does not have access to the vehicle and a real-time location is not needed. Details Access: Access to the vehicle is not required. Installation is performed in about five minutes. Stealth Level: This system is small and hidden on the underside of the vehicle. It will not be found unless a thorough search of the undercarriage is made. Operation: This unit is used independently. It is triggered by motion. When activated, the SatTrak 3 will begin taking a recording of the vehicles position every five seconds. At the end of the seven-day period, the system is removed and a spreadsheet of all of the vehicle's positions over the rental period is provided. The information provided includes the hundred block address e.g. (4600-4700 Block Rockland Street, Fairfax, VA), the date, the time, and how long the vehicle was there.

DOPPLER-BASED TRACKER

DOPPLER-BASED TRACKER Real-time satellite tracking systems have a few limitations, such as they do not operate in underground parking garages and they are limited by the cellular network. In cases where SatTrak systems will not function, a Doppler-based tracker is available. This system will not provide a quick, easy location of a subject's vehicle like GPs, but it is capable of sending out a strong beach signal which can be locked onto. It operates in areas where GPs cannot. Once the signal has been locked on, the investigator can home-in and locate the subject's vehicle, regardless of it being underground, in a non-cellular area, or in an extremely rural or urban area. Details Access: Access to the vehicle is not required. Installation is performed in about five minutes. Stealth Level: This system is small and hidden on the underside of the vehicle. It will not be found unless a thorough search of the undercarriage is made. Operation: These units have proven useful when locating a parked vehicle, but do not offer a fast enough response to be used for active mobile surveillance. If a subject vehicle is lost during a mobile surveillance, the surveillance operative can often relocate the vehicle once it has parked, presuming it is within a ten-mile radius of it's last position.
