Is Global Satellite Navigation Systems

(GNSS) reliable enough?

5 November, 2014The European GNSS Programmes

First Europe’s contribution to satellite navigation:

EGNOS satellite augmentation system

EGNOS Augmentation system of GPS

Improves GPS accuracy

European coverage (but under extension in other regions, e.g. North Africa)

Available NOW, free of charge and widely available in automotive receivers

Open Service (OS) Accuracy ~1m, freeAvailable since

October 2009

Safety of Life Service

(SoL)

Accuracy ~1m, compliant to

aviation standards

Available since

March 2011

EGNOS Data Access

Service (EDAS)

Accuracy <1m, corrections

provided by terrestrial networks

Available since

July 2012

makes the difference!

What are the advantages?

GPS

GPS + SBAS

Galileo Worldwide navigation system “made in EU”

Fully compatible with GPS

Initial operational services in 2015

Open service free of charge, delivering dual frequencies

Signal authentication will provide trustability

Open Service (OS)Freely accessible service for

positioning and timing

Public Regulated Service

(PRS)

Encrypted service designed for greater

robustness and higher availability

Search and Rescue

Service (SAR)

Assists locating people in distress and

confirms that help is on the way

Commercial Service (CS)Delivers authentication and high accuracy

services for commercial applications

Second (and bigger) Europe’s contribution to satellite navigation: Galileo global system

Galileo is fully interoperable with GPS

since the design

Galileo will contribute to improved

accuracy and position robustness

Multi-constellation: When buildings block the signal and reduce thenumber of visible satellites,the availability of more constellations ensures a much more accurate final position

Multi-frequency increasesrobustness of the position against jammers,because even if a satellite is not available or providing incorrect data, a reasonable accuracy will be achieved

How can Galileo benefit

connected vehicles?

•Galileo in combination with other GNSS provides improved accuracy,

availability and allows for a faster time-to-first-fix*

Multi-constellation

• Galileo is expected to be the only GNSS providing Open Service authentication, a “digital signature” to ensure no-spoofing

Galileo Authentication

•The strength of Galileo signal, together with an advanced code modulations, makes Galileo better mitigating multipath effects (especially in E5, but also E1)**

Multipath Resistant

• Using the data-less signal with a 100ms length for the secondary code, Galileo allows for an enhanced indoor penetration, improved performances in urban canyon, better performances in noise measurements and improved sensitivity in A-GNSS mode

Data-less signal of Galileo

Enhancement of currently offered

services

Development of newvalue-added services

Satellite Based Augmentation Systems (e.g. EGNOS) capability is commonplace in today’s receivers

Extra accuracy when you need it at no cost

Level of confidence of GPS signal

Multi-constellation (e.g. GPS/Galileo/Glonass) is rapidly becoming the baseline:

Much improved robustness and performance for users

Road GNSS receivers already include satellite

augmentation and multi-constellation

Results from R&D projects funded under European Seventh Framework Programme

GAIN- Galileo for Interactive Driving

Solution for detecting and mitigating

multipath in urban areas

Enhanced Active Green Driving

demonstrated in real scenarios:

• Roundabout: The vehicles velocity is

adapted to the distance and geometry

automatically

• Crosswalk: The speed will be reduced to

make the driver aware of approaching a

pedestrian crossing

• Ecological Driving: The vehicle adopts the

optimal velocity under consideration of the

traffic ahead and all information via C2X

communication
