Methods, a radio network node (110), a wireless device (120) and a positioning node (130) for obtaining a location estimate are disclosed. The location estimate indicates a location of a target radio node (110, 120). The wireless device (120) is operated to obtain the location estimate by use of functionality provided by a cellular telecommunication system (100). A node (110, 120, 130) refers to any one of the radio network node (110), the wireless device (120) and the positioning node (130). The node (110, 120, 130) obtains (308, 312, 316) a reference point for the target radio node (110, 120). The node (110, 120, 130) obtains (309, 313, 317) displacement information indicating displacement, in relation to the reference point, of the target radio node (110, 120). The node (110, 120, 130) sends (314a, 318a)) the displacement information and/or obtains (310, 314b, 318b) the location estimate by dead reckoning based on the displacement information and the reference point. |
