Trip Distance

Option

The tool is designed for calculating the distance travelled by the vessel.

Menu path
→ → Trip distance

Note

The calculation is performed between adjacent positions using the direct geodetic problem for short distances.

Important

The tool is only available when the option is present.

Function description

The total distance travelled and the distance travelled per voyage, watch, or arbitrary time period are calculated simultaneously.

Trip

№	Element	Description
1	Trip distance	Distance travelled per voyage, watch, or arbitrary time period
2	Total distance	Total distance travelled
3	Threshold distance	Coordinate jitter — a distance equal to twice the vessel position fix error. Designed to prevent false counter triggering when moored or at anchor. When at anchor, it is recommended to set the value equal to the turning circle radius
4	Reset Trip	Reset the Trip distance counter (distance travelled per voyage, watch, or arbitrary time period)
5	Reset Total	Reset the Total distance counter. Reset is only available with elevated privileges
6	Service privileges	Obtain elevated privileges

Trip

Important

Distance travelled calculation algorithm:

the calculation is performed between two adjacent positions;
adjacent position: position from EFPS, manual observation, DR, EP;
the minimum distance between positions must exceed the set Threshold distance;
counter increments are calculated once every 30 seconds;
if the distance between positions is less than the Threshold distance, no increment is calculated.

Trip panel

№	Element	Description
1	Counter	Trip distance / Total distance counter panel The panel can be removed from the navigational panel if necessary
2		Opens the Trip distance window for counter management

Note

The counter is purely informational. Counter data is not documented.

Total Distance: distance travelled per voyage, per year, or over the ECDIS service life
Total Trip: distance travelled per voyage, per watch, per arbitrary time period, or through a particular area of water

Hint

The navigating officer may use the counter at their discretion. The use of counters is not regulated by any normative documents.
