And then there is time advance too. It tells in increments of 180m (IIRC) the distance of MS to BS. (Used to calibrate MS to fit nicely in the time division multiplex at BS receiver) Anyway it is not (yet) clear whether we may get this info from GSM modem (just received the data sheets, pfff: 15meg!) If we can get, positioning via GSM may be magnitude more accurate. cheers jOERG _______________________________________________ Openmoko community mailing list [email protected] http://lists.openmoko.org/mailman/listinfo/community
