GNSS network adjustment
Hi,
Ok so what I understand is there might not be a direct path from the way I am producing the baselines to something usable in JAG3D.
No, that's not right. I'm unable to understand your values. I'm unable to derive a relationship between your baselines and your provided coordinates. If I don't understand the problem, I'm unable to answer your question.
So may I ask how do other people produce GNSS baselines that can be used?
Let us take a look to an example, given in Hofmann-Wellenhof et al, p. 59ff.
The fixed reference point is given by
SB 4213857.480 1025292.070 4664733.470
the new points read
KK 4214436.777 1025493.730 4663835.190 KS 4213099.408 1022546.373 4665836.887 LK 4215184.630 1021692.539 4664261.604
and the observed baselines are given by
SB KK 579.297 201.660 -898.280 0.01 0.01 0.01 KK KS -1337.369 -2947.357 2001.697 0.01 0.01 0.01 KS LK 2085.222 -853.834 -1575.283 0.01 0.01 0.01 SB KS -758.051 -2745.673 1103.395 0.01 0.01 0.01 LK KK -747.852 3801.192 -426.417 0.01 0.01 0.01
The published results are
KK X 4214436.785 Y 1025493.739 Z 4663835.181 KS X 4213099.421 Y 1022546.388 Z 4665836.874 LK X 4215184.640 Y 1021692.551 Z 4664261.595
And the adjusted results given by JAG3D are
Thus, JAG3D was able to reproduce the results given in Hofmann-Wellenhof et al, p. 64.
The question is, why it is impossible to transform your original baselines to the baselines derived by coordinates?
