Raw variables derived from Furuno data files

FSV-25 scanning sonar data files (.nc)

Echoview can derive the following variables from .nc files based on the netCDF4 convention:

• Sv beamformed pings Hn
• Sv beamformed pings Vn
• TS beamformed pings Hn
• TS beamformed pings Vn
• heading data
• pitch data
• roll data

Where:

• H and V are ping mode descriptors
• n is an integer

FSV-30 (Research version) data files (.fsv)

This transducer model is sometimes abbreviated to Furuno FSV-30R.

Echoview can derive the following variables from .fsv files:

• magnitude beamformed pings M
• Sv beamformed pings M
• position GPS fixes
• heading data

Where:

M = Mode identifier, being one of: H1, H2, V1, V2, H1L, H2L, V1L, V2L, S1, S2, S1L, S2L

where: H, V and S are ping mode descriptors, L denotes low gain (the absence of 'L' denotes high gain) and a digit denotes the channel number.

FQ80 echosounder data files (.hac)

Echoview can derive the following variables from Furuno FQ80 .hac files.

angular position pings Tx from files named PingAn01.hac Sv small-cell pings Tx from files named SCSVn06.hac or SSVn03.hac single target detections pings Tx from files named TSn04.hac position GPS fixes from files named pos.hac

Where:

x = transducer number
n = channel number

ETR-30N data files

Echoview can derive the following variables from ETR-30N data files.

Sv pings F from files named HF*.bin or LF*.bin angular position pings F from files named Ph*.bin position GPS fixes from files named LL*.bin

Where:

F identifies the frequency used, being one of:
	HF for high frequency LF for low frequency

FCV-30 data files

Echoview can derive the following variables from FCV-30 data files:

• Sv pings (channel A)
• position GPS fixes
• TS pings (channel B)
• angular position pings (channel C)

FCV-38 data files

Echoview can derive the following variables from FCV-38 data files, where x is the transducer number:

• Power dB split beam pings
• Sv split beam pings Tx
• TS split beam pings Tx
• angular position split beam pings Tx
• position GPS fixes
• heading data
• roll data
• pitch data
