Environmental Commands
The Sentinel V Real-Time uses the following commands to control the environmental and positional in-
formation that affects internal data processing.

Environmental Command Descriptions
EA – Heading Alignment
Purpose
Corrects for physical misalignment between Beam 3 and the heading reference.
Format
EA±nnnnn
Range
±nnnnn = -17999 to 18000 (-179.99 to 180.00 degrees)
Default
EA00000
Recommended Setting. For systems that are stationary, EA is typically set to zero (default), since Beam 3
is used as the heading reference. This command is added to the command file using
Plan
.
Description EA is a heading alignment angle (referenced to Beam 3) used as a new zero reference for
heading output and for transformation to earth coordinates. Use the EB-command to cor-
rect for heading bias (e.g., magnetic declination).
