u32
timestamp_msec
msec since power on
u32
ping_number
assigned sequentially from power on
float
sos_mps
speed of sound, meters per second used for these computations
float[3]
up_vec
world up vector (x,y,z) in the device coordinate system. x forward, y port, z up.
float[3]
mag_vec
reserved for future magnetic vector in the device coordinate system
u32[10]
reserved
for future additions
float
water_degC
-1000 if sensor not installed
float
water_bar
water pressure in bar. -1000 if sensor not installed
float
heave_m
reserved for heave in meters. not implemented so will be 0.0
float
start_m
range at the beginning of the analyzed signals for this ping
float
end_m
range at the end of the analyzed signals for this ping
u16
unused
u16
num_points
number of points reported in the points field
float[2*num_points]
yz_point_data
Y and Z value pairs for each detected point. Y is athwartships offset in meters, positive to the port side. Z is depth, positive up so all z values will be negative.
