Compared While it's still too early to tell how Xtrac v2 will perform in each and every environment, it has nearly all the dynamics of the ST mode with a minimal delay that will no longer confuse navigation software with a high level of sensitivity that will come in handy for use in poor conditions such as urban canyons, heavy foliage or simply if you wear your GPS receiver at your belt. As usual, a picture is worth a thousand words, so hopefully the three pictures below will help: ST, XTv1 and XTv2
So as you can see, much better "sticking" to the road than Xtrac v1 and improved sensitivity of about 20% (Xtrac v1 was about 30%) over the ST mode.
Posted 08/16/04 - Mitac Mio 168 ST vs Xtrac v2
I recently did a side by side comparison using the exact same hardware, the Mitac Mio 168, one running in ST mode, the other one in Xtrac v2 mode. Here are the results:
OziCE Tracks On the left - ST and on the right - Xtrac v2. As can be seen, ST "sticks" to the road a bit better than Xtrac v2 that tends to "cut short". This should normally not confuse road navigation software.
Raw Data Analysis A big improvement in sensitivity that will have the immediate impact of reducing the number of lost GPS fixes!
