I hadn't thought of looking for AT commands.

The canonical command [1] to get location information appears to be
+CMOLRG (Mobile Originated GPS Location Request).  Unfortunately the
N900 does not support this.

Another option, which I found, is +CENG.  Unfortunately, the N900 does
not support this one either.
