Conversion from .kml, global orbits: Arc not treating polar orbiting paths correctly

Hi all,

Not sure if this is the correct forum for this question/problem, but I couldn't find a strictly projecting category.

Anyways, I have a few thousand KML files that each have a single polyline, each representing a single satellite orbital path. I am putting them through a script that converts to each file to layer and appends them to one giant gdb, then projects the gdb into Sinusoidal. I'm not quite sure if this is occurring with the conversion to layer/gdb or the projecting (I think it's the conversion), but when it comes time for the orbit to circle around the North pole, it seems that ESRI doesn't know what to do. I've attached a screenshot of what one of the orbits actually looks like, both unprojected (1st image) and in sinusoidal (2nd image), and an edited version of the sinusoidal orbit, according to the way I think it is supposed to look like (3rd image). Additionally, I've attached a screenshot of what the same orbit looks like as it goes around the pole in Google Earth (4th image), since that's the only place I can view KMLs it seems.

Does anyone have any suggestions on how to get around this issue? I need these to be accurate to do some analysis on the paths of the orbits, and the incorrect conversion is going to interfere with that badly. To do the analysis I have to work with shapefiles or geodatabases because there's not much I can do with just the kml in terms of what I need to get done. Manually editing is out of the question as there are thousands of polylines.

Any comments/suggestions/resources would be very helpful.
Thanks a lot


*EDIT: I changed the title to reflect updated problem. Looking at the 1st image, I'm pretty sure the problem is with the conversion and not the projection.
