This is cool. Rakon, a 39-year-old New Zealand-based company, has developed the world’s smallest GPS receiver. Claimed to be as tiny as the size of a baby’s fingernail, the GPS receiver chip is small enough to be fitted into devices such as watches and cell phones. As GPS becomes commonplace in our everyday gadgets, we can be sure that things will get a little more interesting.

Brent Robinson, Rakon’s Managing Director, also mentioned that the GPS receiver will have sensitivity good enough to pick up weak signals, perfect for urban environments with high interference. Let’s see how long before this baby gets plugged into every of our favorite portable gadgets.

When Freedom Input first emailed me their Press Release about their new Mini Keychain Bluetooth GPS receiver (hereafter I'll just refer to it as the "Mini"), I couldn't believe what I was reading.

Well as compact as those two receivers are, the new Freedom Mini is not only a fraction of their size, but actually out-performs both of them.

The receiver, which weighs about one ounce, and is literally the size of my car's remote "fob", has a mini-USB port on its bottom edge, covered and protected by a hinged rubber door. This little plug keeps the dust and crud out of the tiny charging port, and the rubber hinge keeps it permanently mounted to the receiver's body so you can't lose it.
