Header header
# The represented azimuth angle (angular difference between a given direction and north/east)
float64 azimuth
# Variance of the measurement (i.e. standard deviation squared)
float64 variance
# Unit of measurement:
# RAD: radians, default
# DEG: degrees (not suggested by REP-103, but are more human-friendly)
uint8 UNIT_RAD=0
uint8 UNIT_DEG=1
uint8 unit
# Orientation type:
# ENU: default, 0 degrees on east, increases CCW, follows to REP-103
# NED: 0 degrees on north, increases CW (consistent with the touristic magnetic compasses)
uint8 ORIENTATION_ENU=0
uint8 ORIENTATION_NED=1
uint8 orientation
# Which north reference is used:
# MAGNETIC: magnetic north, changes in time
# GEOGRAPHIC: geographic north, stable in time, also called "true azimuth"
# UTM: UTM grid azimuth, based on GEOGRAPHIC, but accounts for UTM grid convergence; valid only in specific UTM zone
uint8 REFERENCE_MAGNETIC=0
uint8 REFERENCE_GEOGRAPHIC=1
