Data Types

The Real-time Scenario Generation (RSG) commands transfer the data as ASCII strings. However, coordinate systems, units of measure, Earth Models, base data types and accuracy limits are required to implement this in the software. These attributes and values are listed in this section.

Coordinate Systems

• Geodetic (Cartesian)
• Earth Centered Earth Fixed (ECEF)

Earth Model

• WGS-84

Timestamp

• Time into scenario is given in second and 100 millisecond accuracy.
