Does weak signal level affect timing accuracy?
No. If the unit is able to acquire and decode the data, the accuracy is just as good as with a strong signal level. There is no gradual degradation of timing accuracy. The time data encoding scheme ensures that if the data is decodable, it will be valid. The unit is able to receive and decode data even with very poor signal levels. It only has to be able to decode one low-speed CDMA channel, unlike cell phones that need to decode multiple high-speed data channels.
