Abstract:	A deeply integrated GPS/low-cost IMU system is developed and applied to re-acquire and track GPS signals with low carrier-to-noise ratio (CNR). The system provides continuous carrier phase tracking without requiring the knowledge of navigation data bits. Flight data with a 90-degree turn are applied to demonstrate re-acquisition and continuous carrier phase tracking of 15 dB-Hz GPS signals.
