History of satellite positioning
• Originally for military purposes to replace terrestrial navigation
• NAVSTAR, later GPS, started in the 1970s – with a few satellites system
• Position data based on trilateration
GPS“global positioning
system”• Receiver reads signals sent from the
satellite network.
• When enough signals received, the position is calculated. 3 signals will give an unprecise position, generally 4 or more satellite signals are needed for accurate positioning.
A-GPS“assisted -gps”
• In addition to GPS-data, local reference data such as a mobile phone station’s data is used to assist in positioning.
• Less visible satellites needed
• More precise positioning. Speeds up getting the first positioning data.
