Satellite Visibility to Aid Claus Mission

In lead position on a sleigh rising from the North Pole to a height of 200 meters — standard cruising altitude for global package delivery — at 2100 hours UTC on December 24 — the youngest will hopefully be asleep by then and there’s plenty of territory to cover before dawn breaks, time’s a-wasting — navigator Rudolph will see between 40 and 45 GNSS satellites glistening in the night sky.

DoD on Innovation Fast Track: Views Of Top Pentagon PNT Managers

Reducing the number of GPS receivers installed or carried while tapping multiple PNT sources.

Prototyping and beta testing are techniques closely associated with Silicon Valley, the innovation engine admired around the world and, in particular, inside the Pentagon. Simply introducing a new idea has been known to take years in these halls; witness the long introductory saga of GPS itself in the 1970s.
