Abstract
A method () of frequency drift prediction for use by a positioning receiver () can include the steps of determining () a moving average of a frequency error, determining () a moving average of a frequency drift rate in a communication device, determining () a frequency drift rate uncertainty, and providing () the moving average of frequency error and frequency drift rate, and the frequency drift rate uncertainty to the positioning receiver. A point-to-point slope from the running average of the instantaneous frequency error and a running average of the point-to-point slope for a predetermined time period can be determined (&). The frequency drift uncertainty or window is determined using information determined from the moving average of the frequency drift rate. The positioning receiver can be a global positioning receiver.
