Hybrid positioning and CellLocate

®

☞

Hybrid positioning and CellLocate® are not supported by the TOBY-R200-02B-00 and the
TOBY-R202-02B-00 type numbers.

Although GNSS is a widespread technology, its reliance on the visibility of extremely weak GNSS
satellite signals means that positioning is not always possible. Especially difficult environments for
GNSS are indoors, in enclosed or underground parking garages, as well as in urban canyons where
GNSS signals are blocked or jammed by multipath interference. The situation can be improved by
augmenting GNSS receiver data with cellular network information to provide positioning information
even when GNSS reception is degraded or absent. This additional information can benefit numerous
applications.
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 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 deep scan is not supported by “02” / "42" / "82" product versions.

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
