(note: even though i'm running rawhide, this issue has nothing to do with rawhide itself, so i'm using the regular list.)
having never messed with GPS software running on linux, one or two truly beginner-level questions. if i want to simply buy a GPS receiver and set up my fedora laptop to start receiving raw NMEA data, once i purchase the receiver and install something like gpsd, is there any additional expense in terms of a monthly service subscription or anything like that? (i warned you this would be a dumb question.)
i'm interested primarily in experimenting with receiving/parsing NMEA data, the kernel modules involved, etc., so i don't need spectacular performance or precision. i'm in california next week so i figured i'd check out these two USB GPS receivers:
http://www.embeddedworks.net/satl114.html http://www.embeddedworks.net/satl116.html
then i'd install gpsd (or equivalent if one exists), fire up a client and start reading data. is there any more to it than that? also open to recommendations for other GPS receivers if anyone has good experiences.

There is no other expense, unless you want to get into tying in your location to map data from a non-free source. I use an older Holux puck-type receiver, similar to your first selection. Since my upstream is somewhat flakey due to the variable latency problems introduced by my incompetent last-mile provider, I provide my own NTP stratum-0 reference clock from the NMEA stream.

i suspected as much, just wanted to make sure. i suspect that, once i pick up a decent receiver, the setup and usage will be fairly straightfoward.
