GIANT

GPS Interference and Navigation Tool

GIANT is a mission-level simulation that evaluates the impact of Position, Navigation, and Timing (PNT) system performance on operational effectiveness in a benign or electronic combat environment.

A Proven Tool

3D GIANT Screen

Created in 1996 to support the NAVWAR AoA, GIANT has been applied to hundreds of analyses by civilian and military user communities in support of research and development, acquisition programs, test and evaluation, training, concept of operations development, mission planning, and operations.

Continuously
Evolving

Giant 3D

GIANT has been continually upgraded, adding fidelity and functionality, to reflect the evolution of the GPS enterprise architecture, GPS augmentations, other GNSS, and network- centric technologies. As the Air Force’s standard model for GPS, GIANT has evolved from a constructive simulation and analysis tool to support live and virtual exercises and experiments, web-based applications, and air and space operations centers.
