Abstract

Tall buildings that block, reflect, or diffract signals challenge GPS positioning in urban environments, resulting in positioning errors. This paper explores the use of communication signals, such as long-term evolution (LTE) signals, as signals of opportunity (SOP) leveraged to aid navigation performance. Data collected during a driving experiment in the urban center of Denver, Colorado is processed using a carrier phase tracking architecture, which provides accumulated Doppler ranging (ADR) measurements. This data is applied to the problem of characterizing LTE small cell transmitter clock and position states, a critical first step in use for navigation. Batch LLS phase profile comparisons and shadow matching techniques are used, and their combined application matches LTE transmitter locations to candidates in a known database.
