0198 shipLongitude 8 DOUBLE Ship’s longitude in decimal
degrees. †*
0206 navEasting 4 FLOAT Computed fish position in
meters if navUnits are m. When
the navUnits are degrees, the
navEasting and navNorthing
fields are combined into one
double-precision floating point
value to hold navLatitude.
0210 navNorthing 4 FLOAT
0214 cableTension 4 FLOAT Cable tension in from serial port.
†*
0218 conductivity 4 FLOAT CTD Conductivity frequency. †*
0222 navFishHeading 4 FLOAT For backward compatibility with
S-MIPS files only. All zeros. Not
currently used.
0226 navFishSpeed 4 FLOAT Fish speed in knots from nav
telemetry or computed from
navigation telemetry N and E
velocities, used in imagery
display calculations. If speed is
not available from navigation
telemetry, navFishSpeed is set
to shipSpeed or calculated from
point-to-point towfish position.
0230 navShipGyro 4 FLOAT Ship’s heading in degrees
displayed on status monitor. †*
0234 auxVal4 4 FLOAT Auxiliary telemetry value, user-
defined; displayed in Isis
Sensors box. †*
0238 navLongitude 8 DOUBLE Computed fish position in
decimal degrees if navUnits are
degrees, otherwise zero.
