Navigation Calculator
By DBG Nautical
This app is your companion for all your chart work: it covers primary chart plotting issues, rhumb line calculations and nice circle calculations. Whether you are a student, a instructor or an expert navigator, you will certainly profit by using this app. Comprehensive assist pages clearly point out the information to be crammed in, and expected outcomes.
All calculations are executed in a few seconds and you get an entire overview of the major points step by step (ideal for checking your manual work) as nicely as a graphical illustration of programs, speeds, distances and positions. You can calculate for various projections: Plane, Mercator or WGS84 (as used in ECDIS). See our theory part for more background on projections.
The chart plotting part treats the bottom issues: course to steer and course over the bottom. Related topics have been added like set and rate of tidal stream, interception course and wheel over level. All calculations have a graphical view, also clearly explained within the theory section.
With the rhumb line (loxodrome) calculator you calculate course and distance between a departure place and an arrival position, or discover the estimated place ranging from a given departure position and a course and distance to go. The graphical illustration is a real asset.
The nice circle calculator (orthodrome) let’s you discover the gap, initial course and final course between a departure and arrival place. It also calculates the vertex and performs some evaluation: cross monitor analysis, protected latitude analysis and waypoint calculation along the nice circle. The calculation details present totally different methods like ABC tables, Haversine and Napier. Read the assistance pages carefully.
Finally with the ETA calculator you establish date and native time of arrival based mostly on voyage knowledge like speed and distance.
Our principle section is once more a reference on nautical charts and on basic chart plotting. The introduction is about SOLAS and IMO necessities.
We hope this app will improve your daily work and efficiency!
