Sony was first to market this GPS tracker that can remember where you took your pictures. But in their Sony-centric world, they made the GPS-CS1 to work only with Sony Cyber-shot cameras.
Perhaps stung by a new competitor â€“ GiSTEQ, which touts compatibility with all digital cameras â€“ Sony promptly updated their device and called it the GPS-CS1KA. The new device now works with virtually all digital still cameras.
The GPS-CS1KA works â€“ and looks â€“ just like its older sibling the GPS-CS1. It records a location log every 15 seconds. When a photo is taken between two log points, the supplied GPS Image Tracker software estimates the locations by extrapolating from logs recorded before and after (before or later) photos are taken. The software then creates an estimated location between the two recorded locations.
If the user takes a photo when there is no satellite signal available, such as when going underground or indoors, the software makes its estimation in the same way, based on the two nearest location logs.
