Survey scanner won't preform orbital survey

[Two of Three]

I attached a survey scanner on a vessel, put it in a stable orbit between 60 and 150 km, and it didn't allow me to preform the orbital survey. It still said "You must be in a stable orbit between 60- 150 km". Please help and thanks.

Hi Two of Three, you need to be in a polar orbit
