Techniques are provided that may be implemented in a mobile device to provide one or more location parameters to one or more mobile processes (e.g., applications) provided and/or otherwise supported, at least in part, by the mobile device. For example, a mobile device may be configured to monitor one or more processes hosted on a first processor, and initiate a communication on a bus connecting the first processor to a positioning engine external to the first processor to obtain at least one updated location parameter in response to detection of activity of at least one of the one or more processes. In certain instances, the updated location parameter(s) may have been previously determined by the positioning engine.
