| 5 | === TA-Based Positioning |
| 6 | |
| 7 | In TA-based positioning, the serving Cell Id and the Timing Advance (a.k.a. |
| 8 | Access Delay) are provided by the BSC. OsmoSMLC returns a GAD "ellipsoid point |
| 9 | with uncertainty circle" as location estimate. The ellipsoid point is the |
| 10 | latitude and longitude of the serving cell, and the uncertainty circle is the |
| 11 | maximum distance from that cell based on the Timing Advance information. |
