Secure PNT
Time: The Cornerstone of Secure Position, Navigation and Time (PNT)
What is PNT?
Position
A PNT end user’s location is determined by the elapsed time microwave signals take to travel between satellites and the PNT end user.
Navigation
Velocity and acceleration are determined by the change in end user location over a period of time.
Time
Atomic clocks are used at the core of every PNT system to determine precise and accurate time.
The Secure PNT Chain
PNT Core: Time Creation
Our precise and accurate system atomic clocks create the time that is at the core of every PNT system.
Recommended Products:
PNT Transmission: Time Delivery
PNT information is transmitted through space using atomic clocks and quartz oscillators as time and frequency references. Local distribution on the ground is achieved using PTP grandmasters and NTP enterprise servers.
