ating barko and then determining the

selection between primary and secondary

position source including its automatic

change over Okay kasama din yung

ating ating

manual

positioning manual positioning ng ating

barko sa

eis Kasama rin at yung Syempre iung mga

position source niya pakikita natin kung

saan yung setting Okay let's start

guys okay to open the monitoring panel

by selecting the appropriate line of

task list menu on the control panel so

sa control panel sa kanan May task list

i-activate niyo lang guys yung

monitoring Okay After that

monitoring ay lalabas na yung root

monitoring page Ayan sa monitoring panel

yung root monitoring page muna ang

gagamitin natin Okay dito sa root

monitoring page Okay dito sa

shift natin dito ating sh parameter

makikitaan yan yung headline ah display

the course line but usually we activate

the course over the ground t saka yung

heading vector niya display vector

motion relative to the water yan Iyung

heading vector niya and then we can

select

Uh shift by contour and shift by symbol

so Iyung contour makita natin Iyung

shape ng barko in relation to the scale

pag nandun na yung scale na makikita mo

na yung actual size ng barko Okay then

we can have

aine by heading Pwede mo siyang i-align

sa heading and also you can Uh use

window vector wind vector if you want to

activate Pwede mo siyang

makita so you can also use cores and Uh

leg speed pagka activated yung ating mga

course line ung ating root plan

activated kung naka-admit rin natin yan

pag wala hindi mo rin ma-activate so

usually ang ginagamit lang natin

initially is course over the ground

vector and also heading vector to

compare ah d two and you can use also

align by heading and also shift by

symbol ang ah ina-activate

natin Okay so after sa that we can also

Set the

the length of the own sh and target

vector dito yan sa operational panel

window on the control panel Sa Ilalim sa

side bar lower right sa ilalim fix lagay

niyo lang 6 minutes 12 minutes Okay na

yan so maganda mga 12

minutes

vector Okay then we

have Okay then we can set the position

source yung position source naman niya

ay nasa

Navigation Andyan yung kanyang mga

sources ng mga sensor Okay so sa

Navigation panel doon din sa task L sa

kanan sa control panel select Navigation

Then after that okay You will see the

Navigation panel and then you can switch

to shift position ah page Ayan sa shift

position So makikita natin diyan yung

setting setting ng GPS 1 GPS 2 Syempre

always primary ang GPS 1 and secondary

ang GPS

2 Okay

Ayan so Automatic na siya primary pag

bumigay Automatic na siya sa secondary

kailangan lang naka-set siya as

secondary Okay and then Makikita mo yan

sa status mo dito sa control panel Sa

right side sa sidebar pagka select mo

yung primary status Makikita mo

yan okay yung latitude longitude GPS

position yung quality niya d GPS andyan

yyung source Okay after setting that so

confirmation mo yan na you are connected

to the

GPS and then Uh you can set also the

echo

referencing This is better shown in the

Laboratory Okay Syempre secondary siya

pag GPS mo Iyung primary you can set

that as your secondary also primary kung

bumigay na iyung GPS and in order to use

this Of course you must activate the

alpa on the upper right doon sa control

panel r pa okay and of course by

selecting your reference which should be

a steady

target Okay na makukuha niya mapi

niya okay ngayon yan na iyung eco

referencing is demonstrated already in

your

laboratory okay and also the Dr source

you can set it as secondary pag bumigay

yung g GS na isa Pwede mo siyang gawing

secondary or primary kung bumigay na rin

yung dalawang

GPS Okay So yan lang naman yan and then

automatic na siya

mag-deposit Double check your position

in relation to the GPS para ma-double

check mo siya Okay on the right side sa

control panel din yyan doon sa display

panel i-activate mo Iyung task doon and

then doon sa task dis niya Makikita mo

diyan Nandiyan yung manually fix Ayan

Dito Ayan manual fix

ah position Okay so pag inactivate mo

yan yung ah

manual fix then you can have a line of

position para doon sa manual fix

position mo ng iyong

barko Okay then this will appear on the

list after manual fix position

inactivate mo

ah kanina ito manual fix position and

then ito na yung

lalabas it is still on the right side sa

side bar sa control panel yan bandang

lower right lalabas ito itong panel na

ito Okay and then you can

activate you can Activate now the line

of position Okay so yyung pag-activate

ang ah line of position Ganito lang yan

you select

ah line of position number one and then

you enter kung ano yung pipiliin mo no

So may s kang tatlo bearing distance and

bearing distance so usually ah kinukuha

natin dito ay bearing t saka distance o

kung distance distance lang kung bearing

ay bearing kasi mahirap ko munang

bearing distance at the same time so

bearing lang pwede na iyan and then

distance lang kung anong gusto niyo so

bearing pag sinel mo yung ah bearing or

distance so

mentering or distance Depende kung kung

ano yung ginawa mo then you apply that

Okay so It will be Looking Like this

guys pagka ah inapply mo iyan okay line

of position maganda line of position

hang tatlo pero sa dalawa pwede na siya

may estimated position na siya so

maganda Tatlo ang ah kukunin natin then

i-apply ire-refer natin siya

ah dito sa ating

na okay dito ire-refer natin siya move

and reference doon sa reference point mo

bago siya gumuhit So it will be Looking

Like this guys pagka Nagdala na siya

magkakaroon siya ng reference dito

estimated position na and then it will

move to the next number

three Okay so

Iyung automatic ah jump niya it ung lop

dito lang yan pag pagka

magsi-swimming

reference kung sakali n kami Delete mo

lang so magaa na siya kung ilan yung

time difference magaa na siya Okay and

then yung loop advice okay magaadvice

siya rito kung may error pupula yan so

ito kung may error to pupula ibig

sabihin malayo masyado yung kinanan mo

merong error yun mali ibig sabihin pag

pumula yan kailangan activated yung ah

lop advice lop

okay yung Snap to reference unun nga

mag-refer yan Automatic sa reference yan

pagka less than 5 Ayan Magi Snap yan

kung less na pag hindi mano-mano ka ng

mve than reference yung automatic jump

dito lang yan so next na lop ito pupunta

lang siya rito pwedeng hindi mo na

i-activate yan para ah maayos mo to yung

move and reference kung sakali So kung

naman maganda rin i-activate mo rin '

wala namang ah problema rin Ano kaya

lang para lang ma-double Check mo kung

sa akin lang hindi ko na i-activate Ong

automatic jump Okay nandiyan naman yan

iki-click mo na lang naman yan kung

kailangan m Magdagdag Okay so ito yan

pagka distance naman ang kinuha mo guys

Ito naman ang magiging itsura

niyan so bilog naman siya yung mag-cross

yung distance mo doon sa sa reference mo

ito naman ang ilalagay mong reference

yung gitna ng bilog kasi distance yan

yung kanina yung dulo kasi bearing kung

saan mo kinuhanan na reference then yung

bilog niya nag-cross yun ng iyong

magiging position estimated position So

this is better demonstrated guys sa

inyong laboratory ide-date yan okay and

then ah after that then you just

continue merong Alam mo na ay hindi ka

naman nalalayo meron naman na nakalagay

dito error doon sa position mo ilang

difference lang o mailiit lang 0.18

optical Miles lang so Okay na yan 2

hindi masyado nagkalayo siya

no Okay and then we have

Uh another topic setting heading source

Okay doon din si Navigation Nandiyan

yung sensor niya and then after that

select mo rin nandyan sa task L sa kanan

sa control panel Navigation naman yyung

pinili mo and then we have here the

heading Ayan so piliin mo lang yyung

shift

position Okay kung heading source

heading source kung speed ecos sounder

Okay yan lang yan So ano yung source mo

ba o yan

ginagamit o sa heading ah Gyro O ayan

ito Gyro 2 kung may pangalawang Gyro

magnetic magnetic kung meron kang

reference sa

magnetic Okay so yung pinaka source mo

heading mo is Gyro of course yan no

backup lang itong dalawa and then we

have the speed source So ano ba yung

pinagkukunan mo ng source mo ng speed

Okay speed log ayan speed through the

water Okay Ayan then Iyung speed through

the water speed log doppler Log and then

we have here

the speed over the ground GPS naman ang

kinukuha natin yan

normally okay pwede rin mag doppler log

ka ng sim Rod o ito Iyung ships log

speed log ng barko Okay so depende na

kung ano yung available na naka-connect

sa exis natin yun lang ang lilitaw pag

walang nak litaw hindi hindi lilitaw yan

Okay so yung manual laging Meron yan pag

bumigay lahat enter ka manual speed dito

yan Okay so pag bumigay na lahat ang ano

ang sensor mo Ayan na yyung pinaka-last

Resort Okay and then we have

the ecos sounder source so Echos sounder

one yan ang source mo may backup ka ng

ng two kung walang backup nakalagay

hindi MD yan ni eis So kung ano lang

yung nakakakabit yan ang n

lilitaw okay guys so mali maiksi lang
