Semi-Analytic Simulations: An Extension to Unambiguous BOC Tracking

Daniele Borio, Pratibha B. Anantharamu and Gerard Lachapelle

Abstract:	Modern Global Navigation Satellite System (GNSS) modulations have required the development of new tracking algorithms whose analysis is often limited to Monte Carlo simulations. The complexity of such algorithms can result in long simulation times and/or in a limited number of simulation runs. An alternative to full Monte Carlo methods is provided by semianalytic techniques that exploits the knowledge of the system under analysis to reduce the computational requirements of the simulation process. In this paper, the use of semi-analytic techniques for the analysis of GNSS tracking loops is discussed and extended to new Binary O set Carrier (BOC) tracking algorithms such as Bump-Jump, pre-filtering and Double Estimator. The developed semi-analytic model is used for the evaluation of figures of merit such as tracking jitter, tracking threshold and Mean Time to Lose Lock (MTLL). The model is also used for the analysis of phase and frequency lock loops proving the flexibility of semi-analytic techniques.
