I'm trying to get a GPS to work in gazebo, accessing it from player. I modified the various files on interface/player so that the GpsInterface is indeed used. It all seems to work fine, except that I don't seem to be getting any updates, so I never get any data.

I noticed that there are quite a few differences between GpsInterface and, say, LaserInterface, in particular the latter has an empty Update, not the former. Ways to get time also seems quite different.

So how far off is GpsInterface from being usable?

Cheers,

Fred
