Industry’s 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’s 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

× 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’s Smallest

GPS Receiver

By adopting a newly developed GPS

processor (the Sony CXD2931R) and

Sony’s unique high-level high-density

mounting technology, Sony has

succeeded in developing the industry’s

smallest mass produced GPS receiver.

The GXB2000 incorporates all the func-

tionality except the antenna required for

a GPS receiver on a 36.5

× 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).

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.

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.

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.

VOICE

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’ve

come to feel even more strongly

that GPS development has only

just begun.
