Abstract :
The paper presents analysis for using China based Beidou as satellite navigation system in Pakistan´s naval vessels as an alternative or additional aid to US based GPS, which is currently most widely used system. A full scale Beidou will have lower dilution of precision implying better coverage in Arabian Sea as compared to GPS. The paper also compares Beidou open service signal B1 with conventional GPS signal L1. B1 has better performance in terms of multipath error and cross correlation noise. Lastly, design considerations for receiving B1 signal on L1 receiver are addressed in the paper in terms of modifications required in RF front end, signal processing and computing navigation solution.
