icomsat v1.1 + audruino uno location sending

Long time reader first time poster, i'm hoping someone may be able to help with regards to my problem

i'm building a project and curious to know if i can send some location information using on the icomsat, if this isn't possible i can always revert to a gps shield but i would like to keep my build costs down

has anyone trialed a method for locating with something like tower triangulation

accuracy isn't a major concern and i would be happy with accuracy within 50 metres
