Change In Station

Yes, MoBo is very flexible in that regard. The way the intercept feature works is that it always gives an intercept based on the connecting line. If there is no connecting line, the intercept is displayed in relation to OwnShip. But if you connect a contact to another contact it will plot intercept between contacts.

Actually, MoBo is designed to be usable for relative motion problems without even having a background image of a maneuvering board. I could've easily plotted the same solution with a blank background, or a nav map screen print.

Here's the same answer with OwnShip as the Flagship.

Notice above the connecting line between "Port Beam Station" and "Cruiser A" allows the "Port Beam Intercept" to be plotted for "Cruiser A" rather than "Flagship". That connecting line is also known as the DRM line (Direction of Relative Motion). CH11_Prob1_Rev.DAT

If I have time maybe I'll post an example as-if MoBo was merely a piece of paper and do a longhand intercept calculation.

If you have some specific examples you'd like to see plotted or a screen print of a nav map, post em.
