In full: Global Positioning System Place ...my criticism here is you have "positioning" and "place" in the same domain, which somewhat falls under the same meaning
Optimistic view: Putting the above aside, maybe it can be seen as just a shop ..."The GPS Place", like you have "GPS Planet" (which fetched $1,600) ...if you do secure that buyer, selling GPS products ...I appraise low / mid hundreds territory (but as mentioned, hopefully the buyer overlooks that "positioning" and "place" comment I made ...its tricky)
