Field is allowed AtoN displacement in meters

< precision >4.0</ precision >

Proposed date of installation/removal procedure <date>

Field is shore filled: dd.mm.yy

Cannot be edited on board.

Sample: <date>27.01.05</date >

Inventory number of actually installed structure <inv1>

Field is filled on board in case field <inv> was not shore filled or actually was installed buoy/sparbuoy with another inventory number.

Sample: <inv1>5036</inv1>

Actually installed type of AtoN structure (buoy body) <model1>

Field is filled on board in case field <model> was not shore filled or actually was installed another type of buoy/sparbuoy.

Sample: <model1>MR-2S</model1>

Actually installed equipment container’s ID <locsysid1>

Field is filled on board in case field <locsysid> was not shore filled or actually was installed another equipment container. In case sparbuoys is not filled. Field can be held empty.

Sample: <locsysid1>98603016</locsysid1 >

Latitude of AtoN’s actual (anchor’s) location <lat1>

Field is filled on board in WGS-84 format:

DD °MM.NNNN’

DD – deg

MM – min

NNNN – min fraction

Sample: <lat1>59&#x00b0;35.1400'</lat1>

Longitude of AtoN’s actual (anchor’s) location <lon1>

Field is filled on board in WGS-84 format:

DD °MM.NNNN’

DD – deg

MM – min

NNN – min fraction

Sample: <lon1>25&#x00b0;11.3500'</lon1>

Actual GPS mode in use:

<gpsmode>

Field is filled on board with GPS quality indicator referenced to moment of position fix (lat1 lon1) Numbers as in GGA message NMEA 0183 standard

0 – fix not available or invalid

1 – GPS SPS mode, fix valid

2 – Differential GPS, SPS mode fix valid

3 - GPS PPS mode, fix valid

4 – Real Time Kinematic. System used in RTK mode with fixed integers

5 – Float RTK. Satellite system used in RTK mode, floating integers

6 – estimated (Dead Reckoning) mode

7 – Manual input mode

8 – Simulator mode

<hdoplevel>

Field is filled on board with GPS Horizontal Dilution of Precision referenced to moment of position fix

X.X – floating point value in string

(sample <hdoplevel>3.5</hdoplevel>)

value depends on GPS receiver model. Digits amount and decimals may vary.

XML Node <hdoplevel> is empty if value is not available.

<depth>

Depth from sea surface in meters referenced to moment of position fix

X.X – floating point value in string

(sample <depth> 25.6</depth>).

Digits amount and decimals may vary.

XML Node <depth> is empty if value is not available.

<heading>

Heading true (measured from North) in degrees

DDD.D°

Sample <heading>123.4°</heading>

XML Node < heading > is empty if value is not available.

<speed>

Speed over ground, knots reported by GPS referenced to moment of position fix

X.X – floating point value in string

(sample < speed > 2.6</speed>).

Digits amount and decimals may vary.

XML Node <speed> is empty if value is not available.

Actual date of installation/removal procedure <date1>

Field is filled on board.

Date format: dd.mm.yy

Sample: <date1>27.01.05</date1>

Notes <comment>

Field is filled on board, if needed.

Please pay attention to the following:

In the XML file buoy RegNr and Name fields must be different for every buoy.

You should always indicate the hemisphere symbol in the coordinates’ fields – N, S, W or E.
