5 These Guidelines define principles and functions for onboard PNT data
processing, taking into account the scalability of PNT-DP.
6 These Guidelines provide recommendations on how to handle differences
regarding installed equipment, current system in use, feasibility of tasks and
related functions, performance of data sources as well as usability in specific
regions and situations.
7 A structured approach for the stepwise introduction of integrity is
developed to achieve resilient PNT data provision in relation to the application
grades and supported performance levels.
8 These Guidelines aim to achieve standardized and integrity tested PNT
output data to enhance user awareness regarding achieved performance level.
