I’ve been trying to test the GPS on my newly-arrived N810. So far I have not succeeded in getting a fix from my window. Time-To-First-Fix while walking outside (with very good view of the sky) has been 5-10 minutes.
This is not what I had been hoping for. It seems I’ll still be carrying an external GPS with me, at least sometimes — just like like I have to carry a camera with me if I want to take half decent photos, even though my phone has two cameras in it. Good gadgets seem to be difficult to make. Good convergence gadgets are still, in my opinion, mostly an unproven theory.
Otherwise I’m very satisfied with the device: it feels really solid, and I’m still amazed how they fit the keyboard into a device smaller than the N800.
Not SiRF III?
Anyway, about the GPS: There were rumours around the internet that the chipset is SiRF III, but this does not seem to be the case. Internettablettalk forum member ag2 found this string in /usr/sbin/gpsdriver:
GPS5300 is a gps-on-a-chip for OMAP based phones from Texas Instruments. From their product brochure (emphasis mine):
The GPS5300 NaviLink 4.0 solution enables a rapid time to first fix (TTFF) from weak satellite signals… .
- Can someone confirm the chipset details?
- Assuming we do have a GPS5300 on the tablets, does “rapid” have an alternate meaning in Dallas? Maybe it’s just that everything is bigger there, even time-to-first-fix.
