Introducing AC²ES (A-PNT Converged Computer – Embedded & Scalable)

AC²ES is the solution to GPS disruption – a capability designed to provide Assured Positioning, Navigation, and Timing (A-PNT) information at all times. 

Leonardo DRS A-PNT Solution

Developed with efficiency in mind, AC²ES is embedded in our widely used Data Distribution Unit – Expandable (DDUx) II. The DDUx II and military variants are currently fielded on over 150,000 vehicles meaning this capability can be easily implemented without additional space or weight requirements.

Convergence with the DDUx II also allows for ease of use as A-PNT is embedded into the Battle Management System (BMS). The vehicle operator can use the BMS’s Graphical User Interface (GUI) to view and manage GPS and A-PNT functions on a single screen. In addition, A-PNT distribution to all vehicle equipment is supported.

AC²ES is able to provide Positioning, Navigation and Timing (PNT) information by augmenting the standard GPS PNT source. This is achieved through technologies such as:

  • Anti-jam technology
  • Anti-spoof technology
  • M-code receivers
  • Image-based terminal
  • Inertial measurement units

A fusion engine combines system components in order to provide a reliable, GPS-denied navigation solution during real world jamming and/or spoofing attacks. This is hosted in the BMS and can be controlled via its GUI.
