SD GPS receiver add-on
Where most GPS add-ons connect externally to mobile devices, the SDG-810 by Spectec plugs into an SD slot, adding a 20-channel SiRF Star III receiver. Signals are captured by an antenna jutting out of the exposed section. To comfort owners worried about losing their storage capacity, the 810 also manages to fit in a microSD reader, which supports cards up to 2GB in size. Accuracy on the receiver is 32.8 feet in 2D RMS mode but between 3.3 and 16.4 feet in 3D RMS. The weight of the device is just 1.1 ounces. Spectec hasn't disclosed its pricing or distribution plans, but interested parties can contact the company to locate a local supplier.
