Helgo & Others ___ GPS Date Rollover Problem --- Note TNOR does not rely on GPS. Ref TNOR's positioning technology. I understand that TNOR positioning relies on two way communication between a GSM phone's SIM card and a number of GSM Base Stations. I am speculating that the system calibrates the distance from the phone to each Base Station, by measuring the round trip time of a message -- which is sent to phone, and returned to the Base Station, after being processed by the phone's sim card. The processing is based on the fact that Radio Waves travel at 300 million meters per second. Finally, I do have some concern that CDMA phones do not yet use SIM cards. End of Speculation. Any thoughts on this ?? news.com Mardy.
