Navigation Calculator
By DBG Nautical
This app is your companion for all your chart work: it covers basic chart plotting problems, rhumb line calculations and nice circle calculations. Whether you are a student, a trainer or knowledgeable navigator, you will certainly benefit by using this app. Comprehensive assist pages clearly point out the information to be stuffed in, and expected outcomes.
All calculations are executed in a couple of seconds and also you get a whole overview of the primary points step by step (ideal for checking your handbook work) in addition to a graphical illustration of programs, speeds, distances and positions. You can calculate for different projections: Plane, Mercator or WGS84 (as used in ECDIS). See our principle section for extra background on projections.
The chart plotting section treats the bottom problems: course to steer and course over the ground. Related topics have been added like set and price of tidal stream, interception course and wheel over level. All calculations have a graphical view, additionally clearly explained within the theory section.
With the rhumb line (loxodrome) calculator you calculate course and distance between a departure position and an arrival position, or find the estimated place ranging from a given departure place and a course and distance to go. The graphical representation is an actual asset.
The nice circle calculator (orthodrome) let’s you find the gap, preliminary course and last course between a departure and arrival position. It additionally calculates the vertex and performs some analysis: cross track evaluation, protected latitude evaluation and waypoint calculation alongside the good circle. The calculation particulars present completely different strategies like ABC tables, Haversine and Napier. Read the help pages carefully.
Finally with the ETA calculator you establish date and local time of arrival based mostly on voyage data like pace and distance.
Our theory part is once more a reference on nautical charts and on primary chart plotting. The introduction is about SOLAS and IMO requirements.
We hope this app will improve your daily work and efficiency!
