Atlas is a project to produce a GNSS performance quality service and authenticated positioning for use in LBS. The project is sponsored by the European GNSS Supervisory Authority. This is an introductory presentation delivered at Galileo Application Days, March 2010.

2. The Commercial LBS: Shoot & Proof
Shoot & Proof is a mobile software which captures Certified Digital pictures
Picture captures are Geotagged, time-stamped, watermarked and
encrypted at capture
The value chain allows for total integrity control from capture to storage
Photos only
Legal value of the process has been tested and validated
Worldwide patent on the technology
ISO 27001 certified processes
But it remains a very simple 2 click mobile pic capture software Photos &

6. Analysis of the Shoot & Proof Features
 Images, documents and forms are:
 Watermarked
 Advanced digital watermarking 
 Encrypted
 Advanced cryptography
 Timestamping

 Certified from an external time server
 Geotagging

 From the internal positioning engine
 GPS, Cell-ID, etc

8. The ATLAS Project
 Authenticating Time and Location within Liability-
critical Applications and Services
 Successful bid into the latest FP7 GSA call, Use of
EGNOS Services for Mass Market: Innovative
Applications targeted to SMEs
 18 month project, kicked off on 1st February 2010
 3 Project Partners
Slide 8

9. Project Goals
 Address the needs for authenticated GNSS
positioning (& GNSS time) via
 GNSS Evidential Support Service
 Authenticated GNSS Service
 Implement and validate these added services within
the existing commercial Shoot & Proof system using a
subset of the existing customers who are requesting
the features
 The solutions must fit within the existing architectures, in
terms of handset and the data certification chain
 Ambitious project goals and timescale but achievable
through the modification of existing assets
Slide 9

10. GNSS Evidential Support Service
 Provision of a Web-based Service delivering the
nominal performance of GNSS (including EDAS)
 Modification of existing tools
 www.GNSSAssurance.org
 www.EDASMonitoring.org
Slide 10

11. Authenticated GNSS Service
 Ensuring that the location information is of adequate
quality and has not been compromised. This will be
carried out via
 Differential GNSS
 Improving accuracy using an EDAS based server-side service
 GNSS Data Sanity Checks
 PVT, SV info (az, el, snr) consistency and expectancy checks
 GNSS Quality Measures
 RAIM Integrity algorithms
 GNSS Receiver Diagnostics
 GNSS Acquisition and tracking analysis/routines

13. Authenticated GNSS Service:
Existing Assets
 Server side
 EDAS monitoring service to provide position domain correction
 Existing Handset based Features
 Geographical and time based encryption
 Integrity algorithms originating from aviation
 Additional hardware
 Based on NSL’s SDR GNSS
Slide 13

14. Timescales
 GNSS Evidential Support Service by end of 2010
 Authenticated GNSS Service within one year
Certified KO Meeting
