| 1446299 | 2018-02-14 21:33:00 | I want to track and get info on some physical objects placed inside a building and get their Geographic location i.e Lattitude/Longitude I know iPhone provides coordinates but I am not sure how accurate their are, especially since its inside the building. I'm guessing any GPS device will struggle giving info due to no open space. How good is GLONASS enabled devices vs GPS for this purpose? Any better and any specific devices that can give fairly accurate details for this purpose |

| 1446303 | 2018-02-17 03:21:00 | When the GPS tracking device loses sight of the sky due to the blocking effect of the building structure, it will continue to report its location periodically as it was just before it entered the building. Not only would the tracking device be reporting stale, out-of-date location data, there may be a long acquisition delay (possibly several minutes) upon exit as the GPS receiver regains a positional fix. I have heard infsoft work for that. |
