摘要：
Based on the special relationship of dual-frequency carrier phase observations, GNSS dual-frequency integer relationship constrained ambiguity resolution (FirCAR) is proposed, which enlarges the equivalent wavelength of carrier phase in local integer rang, to achieve a fast integer ambiguity resolution. With the code pseudorange and dual-frequency carrier phase observations, the proposed method resolves integer ambiguities satellite by satellite independently. The correctness and effectiveness of this method have been tested by two baselines of different lengths; and the influence of cut-off angle is also analyzed.
