ATLAS PL Personal GPS Locator

personal locator imageThe Atlas PL is a valuable component of an emergency response, search and rescue, wildfire fighting, or security team. Its many unique features make it superb for these types of applications because:The Atlas PL is part of Raveon’s RavTrack GPS tracking technology. It is compatible with the M7 GX transponder and RavTrack PC AVL software.For privacy and security, over-the air encryption is standard on every Atlas PL. For network versatility, the Atlas PL incorporates a 16-bit identification code, allowing up to 65,000 objects to be identified in one system and a “group code” (1-255). For wide-area coverage, all Atlas PLs may be set to store-and-forward messages from other RV-M7 or from other Atlas PL transponders. Although the RV-M7 is the easiest to use modem on the market, and makes the easiest to set up Automatic Vehicle Locations (AVL) system available, its re-programmability makes it extremely versatile.Most parameters within the Atlas PL may be re-configured to optimize it for specialized operations, extended range, or higher data throughput.The Atlas PL is configured using its built-in RS232 serial port.

Raveon provides a software program called Radio Manager to configure the M7. More Details…The Atlas PL has a number of different I/O drivers built into it, allowing it to work with a large range of displays, computers, and PC software applications. Like all of Raveon’s GPS RavTrack GPS tracking products, it has an open software interface, and details of all serial-port messaging is publicly available.

The Atlas PL has multiple applications in military training, and is already being used in bases around America. These trackers aid the in training operations by increasing the safety of the soldiers, and tracking their progress. The man down sensor inside each radio alerts the base station any time someone has gone down for a prolonged period of time, set by the controller. The PL’s incorporate a panic/emergency alert button, that immediately sends and alert back to the base station and controller.

General Features

  • Advanced Safety Features. Automatic “Man-Down”, manual alert, critical alert, and proximity alerts are transmitted along with position and status.
  • Extended Battery Life. 24 operation with very fast updates, and many weeks of operation with slower update rates.
  • Broad Range of Software Options. Raveon’s Ravtrack products are broadly supported by numerous software solutions, including Raveon’s RavTrack PC, CES PT3, Global Mapper, and Google Earth. See http://ravtrack.com/AVL-Software.html
  • Secure. All position reports are 128-bit AES encrypted for secure communications.
  • Critical Alerts. A built-in “Man-Down” sensor along with a manually activated Alert button and a Critical Alert feature allow dispatch and command centers to quickly identify critical situations.
  • Built-In Battery and Charger. The ATLAS PL’s large 2200mAh battery operates the unit for days, and the ATLAS PL may be recharged from any 12V DC power source.
  • Extremely Rugged. The device uses Raveon’s “single-board” construction with GPS, modem, radio, and processor all secured on one circuit board. The light-weight aluminum housing is crush-proof and water-proof.
  • UHF radio channels. No public network access is needed. It works even when the cell systems don’t with no monthly fees.
  • Very Fast Updates. With up to 20 positions reports every second, you can track in truly real-time.
