摘要	Abstract This study has developed an improved real-time kinematic (RTK) algorithm by adding the double-differenced (DD) observations between L1 and L2 frequencies. It also introduces new biases between the frequencies to recover the integer of the DD ambiguities. The validations show that the new bias between the frequencies is stable and can be estimated as a constant in the same reference period. Compared with the standard RTK method, the new RTK model increased the observation number. The availability and reliability is thus greatly improved, especially in environmental conditions unsuitable for observation, and in which the observed satellite number is small.
