Ch 17. Assisted GNSS
Frank van Diggelen, Google
Chapter Overview: This chapter describes how Assisted GNSS works: A-GNSS provides satellite orbits, approximate receiver position, and time to the receiver before it begins acquiring satellites. We quantify the reduction in acquisition search space for each constellation in turn, deriving tables of the satellite speed, Doppler, Doppler rate, and the effect on the size of the search space.
