SBAS 2015 Workshop
Canberra - Australia
EGNOS implementation at
user level
1
SBAS a multi-modal system
Air Carrier & Cargo Aircraft
• SBAS initially created to meet civil
aviation requirements
General Aviation
Air Taxi
Helicopters
Business &
Regional Aircraft
…… SBAS also opens services beyond civil aviation
2
Sol Service
SBAS SoL corrections are available through GEO SIS
3
Open Service
Open service users listen to the same GEO SIS
4
Possible added value services
Additional services are possible on top of SBAS GEO SIS5
Services using SBAS data access server
Access to SBAS data open the possibility of many other services
6
Other services example

EGNOS Data Access: Server a services enabler
EDAS users receive the internal data
collected, generated and delivered
by EGNOS.
•
EDAS therefore provides an
opportunity to deliver EGNOS data
to users who cannot always view
the EGNOS satellites (such as in
urban canyons), or to support a
variety of other services,
applications and research
programs.
data format are available with bounded transit
delay, allowing real-time services
Several data content & format available to fit services needs
8
Services commonalities
Emergency Services
• Locate emergency call (E112 in Europe)
•
•
Routing the call to the closest emergency centre and dispatching it to the most appropriate emergency response teams
Guidance of Rescue teams
Location sensitive billing
Tracking services
• Tracking of children or person with special needs (the elderly, ill, …)
• Fleet tracking, field force management
• Enterprise Resources Planning, logistics
• Worker protection
• Etc…
Navigation services
• Variable billing according to subscribers location
•
•
•
•
(home zone, Office zone, etc…)
Tailored Advertising
Geo Marketing
Etc…
• Navigation and orientation •
to find public places •
(send directions, maps),...
• Real Time distribution of road traffic information
• Real Time information reporting
Within a service there is always a position that is communicated
9
Example of service: Assisted GPS (AGPS) service
Provides ionospheric corrections as well as a very short time to first fix
10
Example of services: PPP service
Precise Point Positioning services
PPP message transmission
•
Bandwidth available for other services
•
PPP message can be transmitted through GEO capable of E5b
11
Example of services: PPP service
Precise Point Positioning services
•
Large service area
– Countrywide
•
Accuracy
– SBAS ~1m
– PPP ~10cm
•
PPP does not require a dense
local network of base
stations (contrary to Real
Time Kinematic (RTK)
technics).
Enable services offering decimetre accuracy
12
Farming related services
Benefits from the offered accuracy
13
Hybridation with other sensors for additional services
Positioning Terminal
GNSS Receiver
(Other sensors)
Location System
(Including other ranging)
Localisation Performances
&
Availability
Hybridisation
Integrity
Authentication
Evolution from a GNSS receiver toward a whole positioning system
14
Rail domain services
• Reduction of ground infrastructure needs
• Train integrity detection
• Improvements in RTMS
• Other services
New emerging needs
