Magnetic Declination
Product description
A Magnetic Declination setting has been added to the ROV Settings > Compass Heading page that can be configured by the user two different ways. Users can either enter the magnetic declination value through keypad or point their ROV in the direction of True North and press a button. This Magnetic Declination is the angular difference between true and magnetic poles.
Problems solved
Depending on the type of work you hope to accomplish with your ROV, some customers need to use headings relative to True North instead of Magnetic North. For example, if you're navigating by map you'll want to use a fixed heading mode (true north) instead of one that variates over time (magnetic north) as the direction you travel could end up being much farther from where you intended to go. Previously we had no way to change this heading mode on our ROVs however we've now added the ability to toggle on True North heading mode once you've determined your ROV's magnetic declination.
