Abstract: Embodiments include methods for estimating movement of an aerial user equipment (UE) in a wireless network based on a plurality of movement models. Such methods include obtaining, from the wireless network, position measurements for the aerial UE at a second time subsequent to a first time, and determining a state of an interacting multiple-model (IMM) for movement of the aerial UE at the second time based on the position measurements. The IMM model includes a first constant-velocity model, a second constant-acceleration model, a third constant-position model, and estimated probabilities associated with the respective models. Such method also includes determining a movement state for the aerial UE at the second time based on combining the models according to their estimated probabilities. Other embodiments include positioning nodes configured to perform such methods.

Abstract: 一种电子设备的GPS周数翻转方法、机器可读介质和电子设备,该方法包括:确定当前时间在预设写入时间范围内(503);判断基于电子设备接收到的GPS信号得出的GPS时间是否满足预设写入条件(504);在判断出GPS时间信息满足预设写入条件的情况下(505),向电子设备写入GPS周数翻转处理程序(506)。通过判断车速、车辆加速度、协调世界时间等参数是否满足写入条件,在参数满足写入条件的情况下,向电子设备中写入GPS周数翻转处理程序。能够在引入车速等参数后提高GPS周数翻转处理程序写入时间的准确性和写入时不会直接导致周数翻转的有效性。

Abstract: GPS-based position reporting suffers from probabilistic error. This disclosure reduces uncertainty by mapping a geometric figure that encompasses a GPS-based reported location and that bounds corresponding predetermined-as-more-probable true locations (MPTL's) among possible locations for the source of the reported location. The mapped figure is overlaid on a relatively accurate mapping of substantially adjacent polygonal areas. Areas of overlap are used for picking among the areas, the polygonal area most likely to be occupied by the source. In one embodiment, the polygonal areas are closely packed parking spots in a parking lot, garage or other like structure, the source is a customer's mobile phone and an attendant is tasked with quickly delivering ordered goods to the customer's parking spot.

Abstract: The embodiments described herein are directed to systems and devices for electronically measuring the absolute position of one or more moving targets e.g., along the length of a metal beam using mutual capacitive sensing. The beam may be made of metal and may have a limited inset area to fit a position detection sensor device along its length. The moving targets may have no active elements and the position of multiple targets may be detected simultaneously along the beam. The systems and devices described herein do not utilize electronic position feedback and instead rely on an integrated ruler and minimize the total number of sensors required to support recalibration, thereby minimizing scan time (more sensors results in a linear increase in scan time).
