Abstract
Shipboard landing of aircraft needs to acquire the real-time and precise relative position between shipboard and aircraft. If the technique of relative navigation based on differential carrier phase is used to solve the problem, the key point is fixing the ambiguity real-time and reliably. In general, wide lane carrier is used to solve the problem. At single epoch, the observable equations of double frequency wide lane carrier are ill-condition, so the code observable equations are needed to add in. Since the poor precision of the code pseudorange information, the ambiguity solved by it can’t reach the performance requirements in shipboard landing. A fitting method by selection of parameter weights is researched based on wide lane algorithm. The method estimates the two kinds of wide lane float ambiguities at first; then solves the individual ambiguity separately. It avoids the problems of poor precision from code equations. The calculation of experiment data shows that the algorithm can solve ambiguity reliably at single epoch and improve accuracy of relative position to centimeter level, which satisfies the requirements for shipboard landing of aircraft.
