Methods and apparatuses are provided for a portable device to minimize power consumption of its measurement engine while maintaining a desired level of accuracy. One such method forms a control loop, in which a value of a metric indicating a difference between the current estimated accuracy and the desired level of accuracy is calculated and then filtered to produce one or more filtered values. Using the one or more filtered values and current values of one or more modifiable measurement parameters, new values for the one or more modifiable measurement parameters are generated and then used to take the next measurement.

Adaptive GNSS power saving control

A GNSS receiver design is tested, which design includes software for generating position/time related data (DPT) based on raw digital data (dRAW) when the software is executed in a processing unit of the receiver. GNSS signals (SRF) are received via a radio frequency input device while moving the radio frequency input device along a route trajectory. The received GNSS signals (SRF) are fed to a radio-frequency front end of a Representative example of a receiver unit built according to the design to be tested. The radio-frequency front end produces raw digital data (dRAW) representing the received GNSS signals (SRF), and the raw digital data (dRAW) are stored in a primary data storage as a source file (Fsc). The source file (Fsc) is read from the primary data storage, and the source file (Fsc) is processed by means of the software to generate at least one set of position/time related data (DPT). Each set of position/time related data (DPT) is stored to a respective result file (Fres), and the result file(s) (Fres) is/are evaluated against reference data (Dref) to determine the performance of the design.

GNSS receiver design testing

A computer-implemented method performed by a UE is provided. The computer-implemented method includes generating, with a first chipset, a first set of geo-fence rules; generating, with the first chipset, a second set of geo-fence rules, which are a simplified subset of the first set of geo-fence rules; transmitting the second set of geo-fence rules to a second chipset; powering down the first chipset; detecting if at least one of the second set of geo-fence rules has been broken; and if at least one of the second set of geo-fence rules is broken, powering up the first chipset to determine if the at least one broken second rule is indicative of breaking at least one rule of the first set of geo-fence rules.
