jTrax Navaid™ Navigation for Military Parachute Systems

jTrax Navaid™ Navigation for Military Parachute Systems Overview SpecificationsSpec SheetsRelated ProductsRelated Training


The jTrax Navaid is a device worn on a jumper’s harness to aid in navigation to the intended Impact Point (IP).  The technology is the same that is utilized in our Guided Precision Aerial Delivery Systems (GPADS), ensuring accurate and proven technology. The Navaid improves safety and increases effectiveness of military jumpers by providing accurate navigation for even the most demanding missions.

The jTrax Navaid system includes:

  • one pilot unit
  • one display screen
  • one support board or a harness
  • one back-up compass (optional)

The jTrax Navaid can have one primary target and two alternate landing targets. A push button located on the jTrax Pilot can be activated with gloves to allow the jumper to rotate through screens and landing areas. The jTrax Navaid is fully integrated with the jTrax Mission Planner software developed by Airborne Systems for GPADS and Military Free Fall operations.

The jTrax Mission Planner is proprietary software that provides mission planning for military freefall jumps well as guided cargo drops.  It allows the user to select mission parameters such as payload weight, canopy, aircraft type, release altitude, speed, heading, and IP location.  The Mission Planner automatically downloads wind data and plans the mission for optimum release point taking into account failure footprint.  The user can then change to desired release points and assess the reliability of alternate plans based on wind conditions, parachute performance and arrival altitude.  This allows customization to meet complex mission parameters without increasing risk due to unknown trajectories or parachute performance.  The planned mission can then be simulated and output to Google earth for visualization and terrain assessment.
