Architecture

 15 Generally, a shipborne PNT-DP is made up of three functional blocks:
  • .1 Pre-processing;

  • .2 Main processing; and

  • .3 Post-processing.

16 The pre-processing function extracts, evaluates, selects and synchronizes input (sensor and service) data (including the associated integrity data) to preselect the applicable techniques to determine PNT and integrity output data.

17 The architecture of the PNT-DP is shown in figure 1.

18 The main processing function generates the PNT output data and associated integrity and status data.

19 The post-processing function generates the output messages by coding the PNT output data (PNT, integrity, and status data) into specified data protocols.
