GPS Multipath Mitigation for Urban Area Using Omnidirectional Infrared Camera

Abstract: This paper describes a precision positioning technique that can be applied to vehicles in urban areas. The proposed technique mitigates Global Positioning System (GPS) multipath by means of an omnidirectional infrared (IR) camera that can eliminate the need for invisible satellites [a satellite detected by the receiver but without line of sight (LOS)] by using IR images. Some simple GPS multipath mitigation techniques, such as the installation of antennas away from buildings and using choke ring antennas, are … Show more

“…In the urban environment, one of the main factors causing the degradation of positioning precision is the GNSS multipath because of the relative lower flight height of UAV platforms. Then, some attempts would be made for the GNSS multipath mitigation [32]. In addition, visual localization is an important clue for the direct positioning of UAVs, which can adapt to some special situations without GNSS signals.…”

“…Primarily the signal quality check serves for the mitigation of NLOS reception, since these effects have the potential to cause limitless errors in the range measurements (Strode and Groves, 2015). Alternatively, the satellite visibility can be determined from camera systems that are aligned to the zenith direction or are equipped with fish-eye lenses (Lohmar, 1999;Meguro et al, 2009;Moreau et al, 2017). These techniques can be used to efficiently enhance navigation solutions in urban canyons and usually accuracies on the meter level are sufficient for tasks, such as distinguishing between pedestrian walkways and traffic lanes.…”

“…• Environmental modeling -describes the explicit modeling of potential external influences such as buildings or infrastructure of cities: [12], [39], [18], [40], [41], [42], [43], [44], [45], [46], [47], [48], [49], [50], [51]. We also propose to include approaches such as a sky-positioning camera within this category.…”
