Question

How 'single','double' and 'tripple'techniques are used in mitigation of gps errors?

Answer 1

I think you are asking about single - triple multi path mitigation technique.  

This technique is used to reduce the error of accuracy.

This is the method for reducing code and carrier phase multipath which uses measurements from multiple receivers in order to obtain accurate estimates of code or carrier phase multipath. Using this method, a least-squares condition adjustment is performed to generate a multipath estimate for each individual receiver/satellite pair.
