摘要: A method for removing biases in dual frequency GNSS receivers circumvents the need ionosphere corrections by using L2(P) combination with either L1(P) or L1(C/A) to form ionosphere-free ranges. table of is stored microprocessor controller memory and utilized computing a location corrected pseudo ranges, system includes receiver adapted store bias values correcting ranges determined L1(F) L1(C/A ).
