Issuses on the Jacobian of the GnssPsrDoppFactor.

Open Nronaldo opened this issue 2 years ago • 5 comments

Dear authors: Could you please tell me how to calculate the doppler factor Jacobian with respect to the position state? I do not understand the codes that are marked by a red cycle in the following figure. I refer to the arxiv version of your article and do not find the details about this Jacobian. Could you give me a guide or reference? Thank you! 多普勒因子对位置的雅克比
