These diagrams describe the issues relating to GPS for indoor positioning and navigation. 
  • Typically you'd consider a pseudo-satellite appriach but which require a specially designed receiver
  • A GPS RF simulator could generate signals that a GPS receiver would interpret as a single (pre-programmed) position (or trajectory) which could be useful for "zone positioning"
  • A GPS repeater would do something similar but the GPS receiver would always interpret at the position of the outdoors GPS antenna
