Description

GPS / GNSS receivers are the outdoor-localization gold standard that indoor sensing literature routinely cites as the "what doesn't work indoors" foil. The whole motivation for indoor BLE / Wi-Fi / UWB localization is that GPS signals don't penetrate buildings. For the thesis, GPS appears only as the rhetorical reference point ("indoors GPS achieves no fix; we therefore need …") and as outdoor-side ground truth for hybrid indoor-outdoor datasets.

Specs / capabilities

  • L1 (1575.42 MHz) and L5 (1176.45 MHz) GPS bands plus other GNSS constellations
  • Outdoor accuracy 1-10 m typical; sub-cm with RTK / PPP
  • Effectively no signal indoors (>20 dB attenuation)

Used by (papers)

  • Outdoor ground truth in mixed indoor-outdoor datasets
  • Motivation paragraphs in indoor-localization papers
