Positioning through cellular information: CellLocate
®
u-blox CellLocate
®
enables the estimation of device position based on the parameters of the mobile network cells
visible to the specific device. To estimate its position the u-blox cellular module sends the CellLocate
®
server the
parameters of network cells visible to it using a UDP connection. In return the server provides the estimated
position based on the CellLocate
®
database. The u-blox cellular module can either send the parameters of the
visible home network cells only (normal scan) or the parameters of all surrounding cells of all mobile operators
(deep scan).
The CellLocate
®
database is compiled from the position of devices which observed, in the past, a specific cell or
set of cells (historical observations) as follows:
1. Several devices reported their position to the CellLocate
®
server when observing a specific cell (the As in the
picture represent the position of the devices which observed the same cell A)
2. CellLocate
®
server defines the area of Cell A visibility
