If you get the weekly Sparkfun new product emails you probably saw this... this could have use as a satellite based tracker in a high dollar Black Rock flight or similar, in place of RF tracker or perhaps as a redundant tracker. Minimum dimension for the bare device is 76 mm which is a tad on the fat side. The price on the manufacturer site is ~ 180 USD.
