I don't think we need to worry about it, but in fact we wouldn't need to dead-reckon. All we would need it for would be to put a ceiling on claims from noisy GPS about what accelerations we could have experienced. If the GPS sample says we jumped 100m in 1s, but the accels didn't really see anything, we could ignore or meddle with the GPS sample. Whether that is any better than just filtering between previous and later samples I doubt. - -Andy -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Fedora - http://enigmail.mozdev.org iEYEARECAAYFAkiRz5EACgkQOjLpvpq7dMpNLQCfcPdC9ZdSelPGiP+D9TVapDI0 94AAnjkmnCWge5RxXewJ40gchhA1n+Ne =jCLG -----END PGP SIGNATURE----- _______________________________________________ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
