Requirement Review
The purpose of this step was the consolidation (specification, definition and planning) of the GGSP.
In detail the following work packages were evaluated:
- "Definition and Realisation of a Terrestrial Reference System (TRS)" (WP210) - The mathematical definition of a TRS, mathematical formulae for transformation between TRS and methods for the TRF implementation as realisation of TRS are formulated.
- "GGSP Requirements Document" (WP220) - The internal and external requirements to the GGSP prototype are defined and summarized.
- "GGSP Prototype External ICD" (WP230) - Interfaces between the GGSP prototype and all relevant external entities are described.
- "Parameters and Models" (WP240) - Necessary standards to be implemented in the GGSP are specified basing on IERS standards, IAU and IUGG conventions.
