Abstract
A control system for a GPS receiver allows adjustment of a number of data collection (i.e., configuration) parameters for the receiver. Preferably, a single interface allows for setting multiple parameters at the same time. Setting the configuration parameters may be in response to a user input specifying a desired quality of position estimate to be provided by the receiver and may be accomplished using a slide bar control. The slide bar control may be a graphical representation displayed to the user and may allow the user to choose from a number of predetermined settings, each corresponding to a set of different configuration parameters for the receiver. Distribution of the settings over the range of a slide bar control need not be linear. Preferably, each set of the configuration parameters includes a setting for a PDOP mask, a signal to noise ratio mask, an elevation mask and a minimum number of satellites to be used by the receiver in making a position computation.
