That sounds painful. | | Common wisdom is that you can't use acceleration sensors to measure | large-scale movements (e.g., to enhance GPS performance), because of | their poor low-frequency accuracy. So continuous integration while | driving wouldn't make too much sense. Yes dead reckoning reliability will be a problem. But sometimes you can do something with even low quality information that you definitely couldn't target with no information. For example, there's enough kicking about to say "I'm travelling in vehicle", from the accelerations, braking and sustained velocity behaviours. Also, if we manage to get something working with the GSM "set" of transponders, maybe we only ask the motion sensors to "fill in" the position with a low level of accuracy until the next GSM sniff. - -Andy -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iEYEARECAAYFAkgMm2kACgkQOjLpvpq7dMqdgACdFNMjhuZQrFgIp1WRlSbBliX0 Pn0An0agEtkB+hZN+PAwm0Lj315kSyXc =BHCM -----END PGP SIGNATURE-----
