In this paper, the methods of earth rotation parameter (ERP) estimation based on IGS
SINEX file of GPS solution are discussed in details. To estimate ERP, two different ways are
involved: one is the parameter transformation method, and the other is direct adjustment method
with restrictive conditions. With the IGS daily SINEX files produced by GPS tracking stations can
be used to estimate ERP. The parameter transformation method can simplify the process. The
process result indicates that the systemic error will exist in the estimated ERP by only using GPS
observations. As to the daily GPS SINEX files, why the distinct systemic error is exist in the ERP,
or whether this systemic error will affect other parameters estimation, and what its influenced
magnitude being, it needs further study in the future.
