Personnel And Offender Monitoring

Loran Technologies has two comprehensive personnel and offender monitoring systems that enables government agencies and private entities to allow for the real-time monitoring and tracking of individuals. The two types of systems are:

1) GPS tracking which allows for limitless range to allow government agencies or private entities to monitor individuals anywhere, anytime using cellular and satellite networks.

2) RFID locator system used ideally in limited areas such as a building, school, complex, or work site and does not require any type or airtime and monitoring fees.


1) GPS (Global Positioning System) Tracking

The GPS tracking system allows agencies and corporations to monitor individuals wherever they may be, anytime and anywhere. This intelligent system uses two forms of technology in one: GPS and RF.

When the tracking device is within the proximity of a home base unit, say the individuals home or some specified compound, it establishes a beacon communication with the home base unit and thereby turns-off the GPS or cellular power circuitry in the GPS unit, using RF to communicate with the home base unit. Once the GPS unit leaves the range of the base unit, the GPS circuitry is turned back on. As well, the base unit contains a motion detector to prevent an offender from moving the home base unit. An optional GSM base unit is available which reports events via cellular network to a monitoring station. This patented technology allows for the unit remain on a single battery charge much longer thereby avoiding the need for the individual to have to recharge the unit on a daily basis (ideal for use on individuals under long-term house arrest).

Both the tracking device and home base units contain anti-tampering parameters in cases of individuals on home arrest so they may not bypass the systems. The GPS unit tracking device uses a patented optical tamper detection strap that attaches the GPS tracking device to the individual and thereby sending a signal in case of user tampering. As well, the home base units contain a motion detector that senses if the individual attempts to move the unit or carry it with him away from home thereby simulating his presence at home. The unit then transmits a motion detection signal to a monitoring station through the tracker unit's wireless communication module.

Optional notification units are available for victim and police notification. The unit detects the offenders GPS unit's short range RF beacon transmission if the offender is within proximity of the victim unit and generates an audible, visual, and vibrating warning signal to notify victim that the offender is nearby. The notification unit then transmits an RF warning signal to the GPS unit notifying offender he is in the proximity of the victim or an unauthorized area and to move away. If the offender does not comply, a GPS signal is sent to the monitoring station of a violation, along with the victim unit ID, the offender unit ID, and the offender's GPS location.

The tracking system consists of software that permits the interface of and data management generated by the below hardware products:

1) A one-piece tamper-proof RFID transponder and GPS/cellular device attached to the individual; and

2) A tamper-proof home base unit used to communicate with GPS unit to recognize when individual leaves or enters home.

OPTIONAL: Same as base unit, but reports event data via a GSM cellular network to a monitoring station.

OPTIONAL: Victim and police unit which notifies victim and police if an offender wearing GPS unit is within it's proximity (i.e. if offender is stalking / hunting down victim).

2) RFID (Radio Frequency Identification) Locator

The RFID locator system is designed use local RF transmission to detect the location of individuals in a given area. Since this unit uses RF instead of GPS/GPRS network, there is no recurring airtime or monitoring charges. All that is required is the initial purchase of the equipment and software. The system is designed specifically for smaller, preset areas.

The system uses wrist/pendant or tamper detecting ankle mount transmitters to communicate via an RF link, through locator units set in the specified area, to an on-site PC interface unit. The system can also be used for inanimate objects such as pallets, containers, vehicles, etc. using tamper detecting asset tags.

Numerous locator units are setup, each to identify a dedicated zone, such as a building, floor, or room. The transmitters, also known as "Tags", each transmit a uniquely coded signal to the nearest locator unit. Once the wireless computer interface unit receives theses signals from the locator units, the software indicates on-screen the user ID and location information to the monitoring personnel.

To increase the area coverage of these locator units, optional repeater units can be installed to extend communication range between locator units and the wireless computer interface unit.

The RFID locator system consists of software that permits the interface of and data management generated by the below hardware products:

1) A RFID transponder attached to the individual or object;

2) A locator unit used to communicate with the base unit at the monitoring station; and

3) A computer interface unit used to receive the signals from the locator units and display the information on-screen.

OPTIONAL: A repeater unit that increase the communication range of the locators to the base unit.


The two systems offered by Loran Technologies are designed for two different needs in mind. The GPS tracking provides a global and anytime monitoring of personnel or offenders using satellite technology, providing constant whereabouts of individuals wherever they may be. On the other hand, the RFID locator system is ideal for monitoring individuals in a prefixed area including, but not limited to, office buildings, school campuses, work sites, military compounds, correctional prisons, medical hospitals, or large complexes.
