She pulled the torch away. The arc died. Silence rushed in.
The geometric arrangement of the available BTSs impacts accuracy. If the MS is surrounded by BTSs, the intersection of hyperbolas is tight, resulting in low GDOP (good accuracy). If all serving BTSs are collinear or clustered in one direction, the hyperbolas intersect at shallow angles, resulting in high GDOP and poor positional certainty. 2g position
In urban environments, signals reflect off buildings and terrain. This creates multiple paths between the BTS and MS. Time-based methods (E-OTD, TOA) assume a direct Line-of-Sight (LOS) path. Multipath signals arrive later than the direct path, causing the calculated distance to be overestimated. She pulled the torch away
“Elias,” she said, “the patch is moving. I’ve got maybe three more passes before it blows.” The geometric arrangement of the available BTSs impacts
She frowned. “What are you talking about? Horizontal groove, vertical face—that’s 2G.”
