The Deluo Universal is a good example of where smaller, cheaper GPS chips can lead. For just $100 you get a tiny box able to track 12 satellites and deliver the results to your PC’s serial port (while taking power from its mouse port). Optional cables at $10 apiece let it work via USB (particularly useful for laptops lacking regular serial connections) or with several PDA models. Also included is Rand McNally street-mapping software. The Deluo is not high-performance, and setup can be a bit fussy, but its simple operation, small size, attractive price, and interface flexibility make it great for someone experimenting with digital charting or as a backup GPS sensor for established systems.
