What is PNT?

Our life is navigation

“We can’t be lost,” said Gurder. “We’re here. We know where we are. We just don’t know where we aren’t.”… „Wings“ – Terry Pratchett

Positioning – Where we are. The navigation is а relative notion. Our position depends on the chosen coordinate system.

Navigation – Movement from one point to another in a determined coordinate system. The navigation needs full navigational information – linear accelerations, velocities and coordinates, angular velocities and coordinates of the object.

Time – The time determines the space. For navigation we need timing. Time is essential for all navigational systems.
