Advanced Tactical Navigation System (ATACNAV)

ASEI’s first contract (1993) was to provide the Autonomous Position Estimation System (APES) for use in tracking and flight control of military target drones.  APES was tested in the QF-4. APES was then modified to serve as the INS/GPS navigation system in the MQM-107E upgrade.

APES was enhanced over the years to meet growing requirements and become the Advanced Tactical Navigation System (ATACNAV), an integrated flight computer and navigation package suitable for use as a flight control computer in precision-guided weapons, manned and unmanned aircraft, ground vehicles, and ships.

The ATACNAV is compatible with a variety of IMU’s and GPS receivers (including both SAASM and M-Code receivers) and can be tailored to customer needs.   Variants range from a high accuracy (navigation grade) system suitable for long-duration inertial navigation flight in GPS-denied environments to small tactical grade INS/GPS systems, and a small-sized low-cost system using COTS components.

The ATACNAV has undergone environmental qualification by the US Navy and US Air Force in addition to formal performance testing by the US Air Force on high speed jet aircraft.
