Industry trends and E-GNSS availability
• Multi-GNSS: Multi-constellation (e.g.
GPS/Galileo/Glonass) is rapidly
becoming the baseline. Together with
other GNSS, Galileo provides:
– Improved accuracy
– Improved availability
– Improved time to first fix
• Industry ready to take advantage of
Galileo:

E-GNSS added value in E112
How can GNSS enhance E112?
GNSS and A-GNSS are good candidates to ensure a
precise caller location:
•
•
In outdoor, GNSS (including A-GNSS) is the most accurate, especially in
rural/ open sky conditions (where network based techniques may
degrade because cells are fewer than in the city)
Cost effective, being (mainly) handset-based and the cost of receivers
now negligible
Multi-constellation mass market GNSS (e.g. GPS + Galileo)
provides average 5-10 meter location accuracy
in the cities and less than 5 meters in rural areas
(outdoor; even without assistance data)
Additional accuracy delivered by EGNOS
GPS
SBAS (EGNOS)
• EGNOS Open Signal added value
• Enhanced accuracy in the position: free of charge and normally the
receivers are designed to process the corrections
• Other services built on EGNOS:
• Provide additional value, such as the enhanced accuracy via A-GNSS
or providing protection level

Added value of A-GNSS and EGNOS:
Test results from R&D project Inclusion
• A-GNSS technology further improves GNSS
performances
• A short time-to-fix, typically 12s
• An improved coverage (Urban and Light Indoor)
• A lower consumption
• EGNOS provides additional accuracy, down to 1.4m

How can Galileo enhance E112?
On top of benefits from multi-GNSS, Galileo provides additional features making it the most
promising GNSS system for emergency caller location:
Multi-constellation
•Galileo in combination with other GNSS provides improved accuracy, availability and allows for a faster timeto-first-fix*
Galileo Authentication
• Galileo is expected to be the only GNSS providing authentication to ensure the signal in space is not subject to
spoofing interferences
Multipath Resistant
•The strength of Galileo signal, together with an advanced code modulations, makes Galileo better mitigating
multipath effects (especially in E5, but also E1)**
Data-less signal of Galileo
• Using the data-less signal, Galileo allows for an enhanced indoor penetration, improved performances in
urban canyon, better performances in noise measurements and improved sensitivity in A-GNSS mode

Conclusions
Summary
• Galileo and EGNOS are expected to improve the caller location in E112 for
following main reasons:
• Better performance (accuracy, availability and TTFF) at no additional
costs
• EU-owned infrastructure under civilian control
• Potential synergies with eCall

Best practices
The US E911 case
•
•
The FCC (Federal Communications Commission) require since 2005 to deliver
E911 service inc. latitude and longitude of the 911 call within specific
accuracy and reliability requirements (phase II):
Accuracy requirements
per 67% of calls
per 90% of calls
Handset-based technologies (e.g. GNSS)
50 m
150 m
Network-based technologies (e.g. cell phone towers)
100 m
300 m
Next developments:
•
By 2019 handset-based stringent requirements to be met for every call

•

•
GNSS to become a standard technology in US phones
Seamless provision of indoor-outdoor location information thanks to hybrid
technologies (e.g. AFLT, network beacon, UTDOA), also providing vertical location (e.g.
allowing to guessing the floor in which the distress person is)
Proposal by US Federal Communications Commission on 20 February 2014
Next Generation 911 (NG 911): enabling users to transmit text, images, video and
data, also by making use of VoIP technology
social benefits in USA estimated to be in the range
of 92$b per year!*
* Up to 10,120 additional lives saved every year in USA, under the conservative hp that only 4% of emergency calls triggered
would benefit of 1 minute improvement, Source: US Federal Communications Commission, 21/2/2014
The European eCall
Good position to save lives
 200 mln vehicles target
starting from Oct 2015 (EC proposal)
 Compatibility with Satellite Navigation Systems,
including EGNOS and Galileo required

contribute to improve eCall location
