My father, Ken Brown, chief engineer for Ferranti and a UK pioneer in developing inertial navigation systems for aircraft, space vehicles, and ships. (Ferranti was a UK engineering firm heavily involved in radar development, electromechanical integrated navigation systems, electro-optics and Mark I, the first commercial computer.)

What popular notions about GNSS most annoy you?
That receivers “talk” to the satellites!
Favorite equation
PR = c(trx-ttx)
PR: pseudo-range (m)
trx: time of reception (sec)
ttx: time of transmission (sec)
C: speed of light (m/s)
As a consumer, what GNSS product, application, or engineering innovation would you most like to see?
GPS “dot” as in the Da Vinci Code movie.
