igs12P1695.itr Residuals between AC solutions and IGS08 for the RF stations
igs12P1695.res Residuals between AC solutions and combined weekly solution
3) Combination Strategy:
========================
The AC solutions are processed using the following procedure:
3-1) The AC solutions are checked/corrected for possible format problems,
station name inconsistencies, etc...
3-2) Constrained AC solutions are unconstrained according to the information
given in their SOLUTION/APRIORI blocks and then minimally constrained.
AC solutions given in the form of a normal matrix are inverted by adding
minimal constraints.
3-4) The weekly AC solutions are combined. The 7-parameter singularity is
avoided by using internal constraints. Iterations are performed until no
residuals exceed 2 cm or 5 sigma.
3-5) The combined solution is compared to IGS08 propagated at current week
(datum). Some outliers may be removed from the datum. Finally, the
combined solution is aligned to the datum using a 7-parameter
transformation estimated using the IGS08 core network.
3-6) The AC solutions NOT used in the combination are compared to the combined
solution in order to identify and remove outliers.
4) Remarks:
===========
mit = mit16957.snx
mig = mit1695g.snx
ITR = IGS08.snx
igs = igs12P1695.snx (weekly combined solution)
IGS = IGS12P27.snx (cumulative solution)
The following solutions are not used in the combination but only for
comparison:

5-1) AC (Variance Factor)^0.5 estimates:
=============================================
At each iteration, the variance factor for solution s is estimated by :
VF = (vs'*Ps*vs)/fs with fs = nobss - tr(As*Q*As'*Ps)
vs : residuals of solution s
Ps : weight matrix of solution s
nobss : number of observations of solution s
As : design matrix of solution s
Q : total covariance matrix
This variance factor is used to rescale the covariance matrix of solution s
for the next iteration.

5-7) Outliers:
===================
Outliers may be rejected at different stages of the processing:
- During the combination (stage 3-4)), outliers may be removed from the
weekly AC solutions. Thresholds are set to 2 cm and 5 sigma.
- During stage 3-6), outliers may be removed from the AC solutions NOT
included in the combination. Thresholds are set to 2 cm and 5 sigma.
- During the stacking of the weekly combined solution on the cumulative
solution (stage 3-7)), outliers may be removed from the weekly
solution. Thresholds are set to 3 cm and 8 sigma.
