Abstract
This paper describes a path planning for Mobile Mapping System (MMS) considering with GPS availability. In a MMS survey, accuracy and efficiency are important factor. The accuracy depends on GNSS availability, which is affected by the road environment. Also, in some operations, MMS have to survey every road in an area. Because of these conditions, it is difficult for navigators to decide MMS's path in the surveys. Thus, we proposed a path planning for MMS considering with GNSS availability. The proposed method weights all links based on the number of visible GNSS and distance between nodes. The number of visible GNSS is calculated by aerial laser survey point cloud and GNSS almanac data. Since the number of visible GNSS changes, the weight of a link is recalculated hour by hour. In a field test, the proposed method improved the GNSS availability and we confirmed the effectiveness of the proposed method.
