Abstract

A design of high-performance low-cost BD2 B1 + GPS L1 dual system module dedicated for applications of navigation is proposed. The module is based on the multi-system multi-frequency high performance SOC chip—“Nebulas TM” which designed by Unicore Communications, Inc. The module takes advantage of the powerful and flexible structure of Nebulas TM, improving the user experiences significantly by enhancing the combined performance of Beidou and GPS as well as improving the performances of individual system. The comprehensive simulator tests as well as real world signal tests show that the key performances including sensitivities, positioning accuracy, TTFF, timing accuracy, positioning in complex environments, stability etc. are superior in comparing with the industry leading products.
