Detailed Description

Sequence of weather vectors in start point/end point representation.

Format:

Repetitive Data Item, starting with a one-octet Field Repetition Indicator (REP) followed by series of four-octet vector components

Structure:

• Bits 40-33 (REP): Number of weather vectors
• Bits 32-25: X1 Component (start point)
• Bits 24-17: Y1 Component (start point)
• Bits 16-9: X2 Component (end point)
• Bits 8-1: Y2 Component (end point)

Resolution:

• X, Y LSB: 2^(-6+f) NM

Note

f is a parameter of the SOP message

Negative values are in 2's complement form
