Parthus Launches and Licenses NavStream 3000 GPS Platform Enabling Location Determination in the Most Challenging of Indoor and Urban Canyon Environments

San Jose, Calif. and Dublin, Ireland - October 9, 2001 - Parthus
Technologies plc (Nasdaq: PRTH, LSE: PRH), a leading developer of
platform-level intellectual property (IP), today announced the launch of
NavStream 3000, a GPS (Global Positioning System) silicon IP and software
platform that delivers greatly enhanced indoor and outdoor positioning
accuracy across a range of devices including mobile phones and
automobiles. The platform has already been licensed to a number of leading
industry players.

NavStream 3000 is the latest and most advanced GPS platform from
Parthus incorporating a configurable GPS baseband acceleration engine,
enhanced radio front end and software suites targeting both handset and
automotive market requirements. While GPS technology offers unrivalled
location accuracy, indoor environments have traditionally degraded
accuracy performance. The significant breakthrough with Parthus' NavStream
3000 is the rapid ability to determine location in practically any
environment. Parthus have undertaken extensive trials to obtain position
fixes in indoor environments including homes, office and industrial
buildings in under 3.5 seconds.

"For the past 18 months, we have worked collaboratively with leading
handset, network and semiconductor players in the industry to identify,
test and finally solve the key challenge of instant and pinpoint location
of individuals whether they be in remote, urban or indoor environments,"
said Dr Tony Pratt, technical director of Parthus' location business unit.
"NavStream 3000 is the result of this extensive test and development
program. The platform delivers in all areas - cost, power, jam immunity,
user privacy protection, GSM or CDMA network assistance, and finally in
the key area of locating an individual in practically any environment and
thereby fully complying with the US FCC E911 mandate."

The US Federal Communications Commission (FCC) E911 mandate stipulates
that wireless 911 emergency callers have to be automatically located
within seconds. Phase II of the mandate requires that carriers who have
chosen handset based location solutions must be selling Automatic Location
Identification (ALI) handsets as of now, ramping to 100% of all
subscribers possessing ALI capable handsets by 2005. With no carrier
having implemented the mandate the FCC granted a short term waiver. The
FCC chairman Michael Powell was reported stating that "efforts (the
carriers' implementation of E911) must be re-doubled. It goes without
saying that there is a new sense of urgency around using mobile phones as
important safety devices." A similar emergency location mandate is
anticipated to be introduced in Europe for the 112 / 999 emergency
numbers. [Given recent heightened media and analyst interest in E911

Historically GPS handsets required sight-of-sky to locate and track
satellites. NavStream 3000 utilizes breakthrough hardware and software
advances to determine exact location in very challenging environments such
as homes, offices, malls and high-rise buildings.

NavStream 3000 incorporates:

Enhanced baseband acceleration: Fully configurable GPS
acceleration baseband (8-64 FFTs) delivering up to 25,000 simultaneous
search windows and under 3.5 seconds to first location fix.

Enhanced software suites: Software suites for both
handheld instant-fix and automotive continuous-fix requirements. Assisted
Capabilities: Platform supports Assisted GPS (A-GPS) for both the IS-801
CDMA and ETSI GSM standards. Software is configurable to support
mobile-based, mobile-assisted, or both network assist solutions.

Optional integrated Java acceleration: Through the
Parthus MachStream acceleration platform, dynamic Java based mapping
programs can be supported for the handset or car.

Optional Enhanced RF front end: Low cost (<8 external
components), low power SiGe BiCMOS RF delivering best in class sensitivity
(1dB LNA) and flexible frequency plan for CDMA, GSM and TDMA clock
sources. NavStream RF foundry sources are available. Works also with other
RF platforms.

The platform was launched to the industry at the ION GPS show in Salt
Lake City, September 12. The platform has already been licensed by several
leading semiconductor players.

"With GPS poised to emerge as a key mobile Internet technology
requirement, our goal has always been to make NavStream the dominant GPS
standard for all mobile devices," said Kevin Fielding, president of
Parthus Technologies. "NavStream 3000, a platform we have already
successfully licensed, is a breakthrough solution which leads the industry
in the four critical areas now driving GPS implementation in mobile
Internet devices. These are the combined requirements for sub 5-metre
accuracy, indoor tracking, low power consumption and of course very low
integration cost."

NavStream's uses extend beyond E911 requirements to enable the massive
drive by wireless operators to generate commercial revenues from mobile
commerce applications. These currently include location based services
such as mapping (real time driving instructions), and personalised
concierge such as nearby taxis, busses, restaurants, stores, ATMs and
places of interest. Revenues from location based services are predicted to
grow from under $10 million in 2001 to $3.8 billion in 2005 (Cahners
In-Stat Group*). Other uses include security (e.g. tracking of hazardous
loads) and logistics (tracking transportation). Some European countries
are deploying GPS for dynamic road tolling.
