    Abstract: PROBLEM TO BE SOLVED: To provide a system and a method for acquiring signal acquisition auxiliary data.SOLUTION: The signal acquisition auxiliary data is acquired for a receiving device like a radio location place-supported position determination device which retrieves a signal from an arbitrary source like a satellite body and a base station. The data can be acquired from data acquired before based upon evaluation of change in parameter like time and position which possibly exerts a bad influence on validity. In some case, the data can be adjusted for the change in parameter. When acquisition auxiliary data provided by, especially, a remote entity includes a more distinct parameter than a generally provided one, data which is made more accurate can be calculated by a receiver using a partial measured value of a signal set. As long as a movement of a mobile station which cannot be corrected is detected and validity of previous data is kept, new data need not be acquired until the validity of the previous data expires because of a limit of extrapolation of time using a Doppler coefficient.

    Abstract: PROBLEM TO BE SOLVED: To provide a system and method to obtain signal acquisition assistance data.SOLUTION: Signal acquisition assistance data is obtained for receiving devices such as wireless position assisted location decision devices seeking signals from any source, such as satellite vehicles and base stations. The data may be obtained from previously acquired data, based upon evaluation of changes in parameters such as time and location that may jeopardize validity. In some cases, the data may be adjusted for the changes in parameters. Refined data may be calculated by a receiver using partial measurements of signal sets, particularly if the acquisition assistance data provided by a remote entity includes more distinct parameters than those which have typically been provided. New data need not be obtained until the validity of previous data expires due to limitations upon temporal extrapolation using Doppler coefficients, unless mobile station movement that cannot be compensated is detected, and jeopardizes validity of the previous data.
