Industry鈥檚 Smallest GPS Receiver Module
GXB1000
GXB2000
By adopting a newly developed DSP (the Sony CXD2931R) and high-
density mounting technology, Sony has succeeded in developing the
industry鈥檚 smallest mass produced GPS receiver.
In particular, the GXB2000 incorporates all the functionality except the
antenna required for a GPS receiver on a mere 36.5
脳
25.0 mm printed
circuit board.
This receiver is not only for use in car navigation systems, but rather
its significance lies in the point that it vastly expands the world of GPS
applications to a wide range of portable equipment.

Industry鈥檚 Smallest
GPS Receiver
By adopting a newly developed GPS
processor (the Sony CXD2931R) and
Sony鈥檚 unique high-level high-density
mounting technology, Sony has
succeeded in developing the industry鈥檚
smallest mass produced GPS receiver.
The GXB2000 incorporates all the func-
tionality except the antenna required for
a GPS receiver on a 36.5
脳
25.0 mm
printed circuit board. This allows a GPS
receiver to be incorporated easily into
portable equipment in which it was pre-
viously difficult to do so.
Sixteen-Channel
GPS Receiver
The CXD2931R is capable of receiv-
ing signals from 16 satellites at the same
time. These 16 channels will become
useful when the number of GPS satel-
lites is increased from the current 27.
Support for multiple channels can
reduce the time to first fix (TTFF).
Differential GPS Support
The differential GPS allows the posi-
tioning accuracy to increase approxi-
mately 10 times compared with GPS
alone by converting the correction data
from the GPS satellites obtained at the
base stations in the DARC or RTCM
format.
Both All-in-View and
Two-Satellite Positioning
These receivers adopt the all-in-view
positioning technique, in which data
from all satellites from which signals are
received is used in the positioning
calculation. This method increases the
positioning accuracy. They also support
the two-satellite positioning technique
that can increase the positioning success
ratio when signals can only be received
from two satellites in locations with
inferior reception conditions, such as on
streets with tall buildings.
Thin-Form Ultralight Pack-
Type Package
Both the GXB1000 and the GXB2000
are provided in a shielded case that
achieves a thickness of a mere 7.4 mm.
Measures for Reducing
EMI (electromagnetic
interference) Provided
The generation of EMI is held to a mini-
mum by enclosing the whole GPS
receiver in a shielded case.

We designed this receiver based
on the idea that if made smaller,
GPS receivers could be used in a
wide range of applications in ad-
dition to in-car navigation sys-
tems. In the future, we will be aim-
ing for even smaller even lower
power receivers. Recently, I鈥檝e
come to feel even more strongly
that GPS development has only
just begun.
