New MS-based E-GPS Combines
High Accuracy All Environment Location And Low Cost Battery Drain In GSM/W-CDMA
Devices

April 21, 2006
CPS (Cambridge Positioning Systems Ltd) today announces the launch of an
MS-based version of its E-GPS high accuracy mobile location technology
for GSM/W-CDMA networks – designed to deliver faster location fixes,
lower cost implementations and reduced power and processing
requirements. |

E-GPS (Enhanced GPS) combines satellite-based location technology with
CPS’s Matrix technology, which measures network-based signalling to
deliver all environment coverage. Effectively, once an end user
initiates a location request, they receive a sub-100m Matrix location
instantly– then CPS’s [+/- 2 microsecond] fine time aiding allows for
acquisition of GPS satellites within seconds.
The benefit of fine time aiding is that the device now knows where to
look for a GPS signal. This enables a more aggressive search and is
equivalent to 6 dB more sensitivity than can be achieved with any amount
of GPS hardware correlator in the terminal. So powerful is this
assistance that it also enables software-only GPS solutions to operate
reliably in all environments.
This new version meets growing demand for seamless indoor/outdoor high
accuracy performance – particularly to support personal navigation and
tracking applications. With all of the positioning and timing
applications, including calculation of fine time aiding, being performed
inside the handset, power and processing requirements normally
associated with GPS performance indoors or in urban areas is radically
reduced – by up to a factor of 10 - for both initial acquisition of GPS
signals and subsequent tracking.
It also means that handset developers can now look forward to smaller,
lower cost, easy to implement E-GPS solutions that can be integrated
within existing platforms without extensive re-design in a single
implementation.
CPS CEO Chris Wade said: “Device manufacturers and operators tell us
they want GPS – but in a form that is at the right performance and price
point. They also say that 70 per cent of location-based services are
being initiated indoors – and yet this is precisely the environment
where GPS fails to deliver an acceptable end-user performance.
“What we can now say is that we have a simple handset-based solution
that breaks through the $5 per device barrier and offers a far more
compelling consumer proposition. With personal navigation a key growth
area for operators, this new MS-based E-GPS provides an ideal solution –
guaranteed performance indoors and outdoors, low battery drain and easy
integration.”
About CPS:
CPS (Cambridge Positioning Systems Limited) delivers cost competitive
high accuracy mobile location technology to the billion-strong customer
GSM and emerging 3G/W-CDMA markets. CPS’s products are based on its
software-only Matrix technology – which delivers sub-100m accuracy,
sub-3 second location fixes and all environment coverage. The product
portfolio extends to Matrix 3G and E-GPS – a powerful combination of
Matrix and GPS technology.
With network deployments of Matrix underway, CPS is working with the
world’s leading mobile technology companies – including Nokia, HP,
LogicaCMG and Andrew - to enable a new generation of high accuracy
location based services and devices for enterprise and consumer markets.
Headquartered in Cambridge (UK), CPS is funded by venture capital and
strategic corporate investors. CPS’s value is underpinned by 20 key
worldwide technology patents – one of the largest and most comprehensive
IPR portfolios of high accuracy location technology in the world. For
