The EGNOS Commercial Data Distribution Service (CDDS) represents the provision of additional data for professional users not provided by the EGNOS signal broadcast by geostationary satellites but by other distribution channels. The CCDS will be offered on a controlled access basis, i.e. Internet based resources or cellular phones, and is intended for ground based customers who require enhanced performances for commercial and professional users. The Service has not yet been declared available and a dedicated Service Definition Document (SDD) will be published upon its declaration.
First step towards EGNOS CDDS: [EDAS | EGNOS Data Access System (EDAS) ]]
In order to gather user requirements for the final CDDS, The European Commission has leaded an initiative, The EGNOS Data Access System (EDAS), to provide EGNOS data by making the following services available:[1]
- Transmission of EGNOS messages via the Radio Data System (RDS) and Digital Audio Broadcast (DAB).
- Transmission of EGNOS data using the RTCM SC 104 standard (directly usable by maritime DGPS receivers).
- Transmission in real time of EGNOS system performance information.
- Access to raw data from the RIMS network receivers.
EDAS is the technical implementation of the EGNOS CDDS, it will constitute the means for the EGNOS multimodal service growth and introduction of the EGNOS CDSS and represents the main interface point for multimodal Service Providers to deliver EGNOS products in real-time, within guaranteed performance boundaries.[2]
EDAS is provided by the European Satellite Service Provider (ESSP), it is the single point of access for the data collected and generated by the EGNOS infrastructure and it represents an intermediate step towards the definition of the EGNOS CDDS by the European Commission.[3]
EGNOS CDDS Applications
Service providers can exploit the CDDS to provide added value to final users in various domains and applications such as the ones highlighted:
- Applications for individual handsets and mobile phones (LBS)
- Road transport
- Maritime & Rail transport
- Civil protection and surveillance
Location Based Services (LBS)
The LBS sector include GNSS-enabled mobile phones, smartphones and services, and represents 52% of the global GNSS market.[4] To promote the development of EGNOS/EDAS based LBS applications, the EC has funded R&D projects to provide toolkits for manufacturers.
In urban areas where acquiring satellite signals may be difficult and often provokes a loss of accuracy and performance degradation, EGNOS corrections could still be applied through the EGNOS CDDS. Some of the latest R&D projects developed in this frames are listed bellow and a the complete list of ongoing projects is described in detail in the EC GNNS Applications site.[4]
- PERNASVIP : to develop a GNSS-based mobility service dedicated to visually disabled pedestrians in urban environment.[5]
- ATLAS : concerns the development of an assurance and authentication service for GNSS-derived time and position information for use in liability-critical LBS applications across a wide variety of market sectors.[6]
