[Nspcsg] Meeting Report

[Pierre LADOUX]

Dear Tim,

thanks for the report. I would have the following inputs/comments:

-Inputs on EUROCAE WG-28 status: new ToR under endorsement. It is 
planned that the main activity will be driven by the development of a 
ground subsystem MOPS that will be in-line with ICAO GAST-D SARPs 
(target date is Q2 2017).

- AI#177: SARPS proposal for separation criteria for GBAS VDB versus VHF 
COM as well as GBAS VDB versus ILS => due date is Feb 2015 and not Feb 2014

- AI#181: VDB link budget issues => I think I made the suggestion that 
any proposed changes are discussed also at CNTSG. That was at least 
welcomed by Laurent but this is not reflected in the report.

- Work plan in relation with AI#183 (Proposed Modification for GAST D 
Anomalous Ionosphere Gradient Requirements): this was not really 
discussed but my interpretation is that validating the new requirements 
will take time. Even if we assume a stable definition of the IGM 
requirements within a relative short-time frame,  we need (at least on 
SESAR side) to consider the necessary time for ground manufacturers to 
implement the changes on the GAST-D ground prototypes and then the time 
to validate them on site. I'm afraid that the validation of the IGM 
requirements by February 2015 is not achievable.

Best regards,
