Group C: indoor position
This group tests how GPS accuracy changes with where a person is inside a building: deep inside, next to a window, near the door, in the basement or on an upper floor.
Each session has 12 planned stops (below). After those, stops 13 to 16 are free: the participant picks any four places and stays at least 10 minutes at each.
Inside = inside a building. 2F-4F = second to fourth floor. Duration = the minimum time to stay.
| Stop | Context | Duration |
|---|---|---|
| 1 | Ground floor, deep interior, 5+ m from windows and doors | 15+ min |
| 2 | Ground floor, back corner furthest from entrance | 15+ min |
| 3 | Mid-interior, 2-3 m from a window | 15+ min |
| 4 | Within 1 m of a window facing a courtyard or alley | 15+ min |
| 5 | Within 1 m of a window facing the main street | 15+ min |
| 6 | Just inside the entrance door (within 1 m) | 10+ min |
| 7 | Against an exterior wall without window | 12+ min |
| 8 | Basement, center, far from entrances | 15+ min |
| 9 | Basement, near stair/escalator entrance | 12+ min |
| 10 | Upper floor (3F+), center | 15+ min |
| 11 | Upper floor (3F+), within 1 m of a window | 15+ min |
| 12 | Under a multi-story atrium | 12+ min |
