Abstract EN
GNSS (global navigation satellite system) compass is a low-cost, high-precision, and temporally stable north-finding technique.
While the nonlinear baseline length constraint is widely known to be important in ambiguity resolution of GNSS compass, its direct effect on yaw angle estimation is theoretically analyzed in this work.
Four different methods are considered with different ways in which the length constraint is made use of as follows: one without considering the constraints, one with simple scaling, one with indirect statistical scaling, and one with direct statistical scaling.
It is found that simple scaling does not have any effect on yaw estimation; indirect and direct statistical scalings are equivalent to each other with both being able to increase the precision.
The analysis and the conclusion developed in this work can go in parallel for the case of the tilt angle estimation.
