Ubiquitous positioning requires services that are supplemental to the existing Global Positioning System (GPS). For spaces where GPS does not work (indoors, canyons, etc.) augmented or enhanced positioning systems are necessary. For such systems to function appropriately users must have a GPS-like experience. In essence, users of supplementary positioning systems must trust the information these systems deliver. In order to develop systems that mimic the trust generated by GPS and to better understand the implications of features or changes to such a positioning system we believe a conceptual model of positioning system trust is necessary. Such a conceptual model must consider several aspects of the user and the system. The system must be accurate, with an informative User Interface that is transparent (provides context and background on positions and how they are calculated), it must use verified source data, and provide information that supports a range of users. In this paper we present the essential elements of trust for enhanced or supplementary positioning systems.
