TSS1 Message
The message format:
:aabbbb shhhhxsrrrr spppp
where:
aa — 2 char hex number with SWAY acceleration, in 0.03835 m/s
2
units.
bbbb — 4 char hex number with HEAVE acceleration, in 0.000625 m/s
2
units.
hhhh — 4 char decimal number with HEAVE position in centimetres, positive up
s — 1 character of sign: ¡SPACE¿ if positive, “–” if negative.
x — Status character. Below is a description of the various characters.
rrrr — 4 char decimal number with ROLL angle in hundreds of a degree.
s — 1 character of sign: ¡SPACE¿ if positive, “–” if negative.
pppp — 4 char decimal number with PITCH angle in hundreds of a degree.
s — 1 character of sign: ¡SPACE¿ if positive, “–” if negative.
The TSS1 data string contains 27 characters in five data fields.
The acceleration fields contain ASCII-coded hexadecimal values.
Horizontal acceleration uses units of 3.83 cm/s
2
in the range zero to 9.81 m/s
2
.
Vertical acceleration uses units of 0.0625 cm/s
2
in the range -20.48 to +20.48 m/s
2
.
The motion measurements contained in the data string will be in real time, valid for the instant when the Sensor begins
to transmit the string.
Motion measurements include ASCII-coded decimal values.
Heave measurements are in cm in the range -99 to +99 metres. Positive heave is above datum.
Roll and pitch measurements are in 0.01 degrees in the range -90 deg (-9000) to +90 deg (9000). Positive roll is
port-side up, starboard down. Positive pitch is bow up, stern down.
Status flag
U — UNAIDED MODE — SETTLED CONDITION
The Sensor is operating without any input from a gyrocompass, a GPS receiver or a Doppler log.
u
— UNAIDED MODE — SETTLING
The Sensor is operating as above but is still awaiting the end of the 3 minutes settling period after poweron or a
change of mode or heave bandwidth.
G — GPS AIDED MODE — SETTLED CONDITION
The Sensor is receiving and using velocity aiding signals from a GPS receiver or a Doppler log.
g — GPS AIDED MODE — SETTLING
The Sensor is receiving velocity aiding signals from a GPS receiver or a Doppler log, but is still awaiting the end
of the 3 minutes settling period after power-on or a change of mode or heave bandwidth.
H — HEADING AIDED MODE — SETTLED CONDITION
The Sensor is receiving and using heading aiding signals from a gyrocompass.
h — HEADING AIDED MODE — SETTLING
The Sensor is receiving heading aiding signals from a gyrocompass but is still awaiting the end of the 3 minutes
settling period after power-on or a change of mode or heave bandwidth.
NOTE! The gyrocompass may take several hours to settle after it has been
powered-on. During this time, gyrocompass aiding of the Sensor will
not be perfect.
The status flag does NOT indicate this condition.
