Abstract:	While the number of GNSS satellites is steadily increasing as the system providers execute their launch programs, it is common already for GPS chip set vendors to support both GPS and the others satellite navigation systems. The combination of multi-constellation will provide greatly improved performance for the end user. This paper introduces the design concept and practical trial testing results of a one-chip multi-constellation GNSS receiver based on the viewpoint from manufacture and consumer level. The integrating multi-constellation GNSS performances with availability, improved accuracy, faster time to first fix and an outstanding decoding performance with -151dBm that is the best performance in commercial product, will be then presented. Especially, an additional output in this paper will be a pilot study of the signal processing of the BEIDOU -2 which China has released the test version ICD for its Compass (BEIDOU -2) GNSS system last year.
