Sažetak

This study explores methods for precise attitude estimation using carrier phases within global positioning systems (GPS). Carrier phase data is preferred over pseudorange data for short baseline distances due to its lower noise levels. However, resolving ambiguities through integer ambiguity resolution methods is essential for effectively utilizing carrier phases. One widely adopted approach, the LAMBDA method, is introduced, alongside a solution tailored for low-cost GPS systems and receivers with higher error. The novel method primarily focuses on utilizing only the fractional parts of the carrier phases while integrating constraints such as pitch and baseline constraints to enhance ambiguity detection accuracy. Comparative analysis with the LAMBDA approach demonstrates that the proposed method achieves remarkable accuracy, even in environments characterized by multipath interference.
