DOI: 10.1007/s10291-018-0713-2
Abstract: GPS positioning is often assimilated to trilateration and even to triangulation methods. Both comparisons are wrong because GPS observations are pseudoranges containing clock errors. The geometric interpretations of GPS relative positioning and trilateration method are… read more here.

DOI: 10.1088/1361-6501/ab1cb0
Abstract: The effects of inter-system biases (ISBs) in multi-global navigation satellite system (GNSS) combined positioning cannot be ignored in zero-differenced observations. Furthermore, for relative positioning of multi-GNSS from double-differenced observations, there also exists double-differenced ISB, and… read more here.

DOI: 10.1109/lra.2022.3145051
Abstract: Precise relative positioning has numerous applications in collision avoidance and lane-keeping/lane-changing maneuvers. For such applications, we need sensors that can precisely estimate the relative position. GPS carrier phase measurements can provide high accuracy if unknown… read more here.
