The success of Galileo for Location Based Services for cellular terminals depends on the availability of appropriate standards. Currently, the Location Services standards developed by 3GPP include Assisted-GPS. The standard shall be extended to include Assisted-Galileo and shall be compatible to the Assisted-GPS standard in order to enable efficient use of both constellations in the terminal, GPS and Galileo. Currently, there are activities ongoing in different 3GPP groups to identify the changes that might be needed to support Assisted-Galileo. In order to develop Assisted-Galileo capable terminals, detailed technical specifications need to be developed. Currently Assisted-GPS standards define assistance data for single frequency GPS receivers (i.e. L1 frequency only)

The objective of this work package is to promote dissemination and exploitation of results from all work packages to influence the future broadband mobile radio cellular (4G) systems, which could take into account solutions presented within the GREAT project, especially location services (LCS) based on Galileo mass-market receivers. o:p

The working tasks include:

• Survey ‘proposed 4G systems’ standardisation activities within Europe and worldwide
• Propose co operations with EU projects related to 4G systems raising awareness on Galileo navigation (e.g., WINNER)
• Identify the key differences between the Galileo and GPS system relevant for the standardisation of the Assisted-GNSS
• Contribute to 3GPP standardisation process on Assisted-Galileo to ensure availability of 3GPP technical specifications in time when the Galileo system is in operation.
• Promote dissemination of project results at international forums such as WWRF to promote a strategic vision of future research on navigation and also to present at international journals, conferences and workshops.
• To provide a summary of standards on 3GPP, 3GPP2 and OMA, ensuring compatibility at a radio and software level with appropriate 2G/3G/3G LTE cellular standards.

Although, it is expected that at least the first wave of Assisted-GNSS terminals will be single frequency receivers, possible required standards extensions to include dual frequency assistance will be investigated.

Both possible modes of operation of Assisted-Galileo shall be considered for standardisation, i.e. MS/UE-based, where position calculation is performed in the handset and MS/UE-assisted, where the handset provides measurements and the position is calculated in the network.
