YZ_POINT_DATA
ID: 3023
Payload Definition
| Data Type | Name | Description |
|---|---|---|
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. |
