Which method is good (in terms of accuracy) to solve a box-constrained optimization problem with 28 variables?

I have a 7 sensors uniform linear array that have some errors to be estimated (i.e. to do array calibration). The errors are: gain, phase, and position (in y and z axes). So, the total is 28...
