The SurePath Navigation System is a laser-based navigation solution that delivers precise and reliable velocity and positioning data in environments where GPS is unavailable or unreliable. It employs proprietary Doppler lidar technology to measure real-time velocity vectors, thereby correcting errors in inertial navigation systems (INS) without relying on GPS signals. The system's design offers exceptional immunity to radio frequency interference and jamming, making it a robust and trustworthy solution for navigation in GPS-denied scenarios across terrestrial, aerial, and space-based applications.
