Abstract

Embodiments provide for methods and portable positioning devices (100) adapted to determine a geospatial position of a point of interest (180). In one embodiment, the portable positioning device comprises an antenna (110), a levelling detector (120), an imaging device (130), a display unit (140) and a processing unit (150). The antenna may be adapted to receive satellite information signals (165)from a global navigation satellite system (160). The levelling detector is arranged relative to the antenna for detecting whether the antenna is positioned horizontally. The imaging device has a sighting axis (135), and a phase center (115) of the antenna is arranged along, or at least close to, the sighting axis. The display unit may be provided for assisting in identifying the point of interestwithin a field of view (132) of the imaging device and for assisting in identifying whether the antenna is horizontally levelled based on an input from the levelling detector and whether the phase center and the point of interest are vertically, or at least close to vertically, aligned. The processing unit is configured to trigger computation of the geospatial position of the point of interest based on the satellite information signals received at the antenna for a position of the positioning device for which an indication that the antenna is horizontally levelled and the phase center of the antenna is vertically, or close to vertically, aligned with the point of interest is received.

Description

technical field [0001] The present disclosure relates generally to the field of positioning, and more particularly to methods and portable positioning devices for obtaining geospatial locations of points of interest. The positioning devices disclosed herein can provide two-dimensional or three-dimensional geospatial locations of points of interest. Background technique [0002] Positioning involves the technique of determining the position of a person, object, or system on or near the surface of the Earth, that is, the technique of determining the coordinates (latitude, longitude, and altitude) of a place. For example, positioning may be of interest in the field of surveying techniques where the purpose is eg point-based determination of land position or three-dimensional position, using relative distances and angles between these points to build land maps. In such applications, the resulting land map will depend on the survey system, components of the survey system, or the...
