Alison Brown’s Compass Points
Systems design, algorithm design, systems integration and testing
GNSS Event that most signifies to you that GNSS has “arrived”.
Selective Availability being disabled to allow commercial users to benefit from full accuracy of GPS
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.)
Other technologies you use frequently
Inertial measurement units and navigation systems.
What popular notions about GNSS most annoy you?
That receivers “talk” to the satellites!
PR = c(trx-ttx)
PR: pseudo-range (m)
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.
