Detailed Description

Sequence of weather vectors in local polar coordinates.

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: Start Range
• Bits 24-17: End Range
• Bits 16-1: Azimuth

Resolution:

• Start/End Range LSB: 2^(-7+f) NM, Max range: 2^(1+f) NM
• Azimuth LSB: 360/(2^16) deg = 0.0055 deg

Note

f is a parameter of the SOP message
