Impact of carrier to noise power density, platform dynamics, and IMU quality on deeply integrated navigation. Lashley, M., Bevly, D. M., & Hung, J. Y.

Paper doi abstract bibtex In this paper, the authors investigate how the Carrier to Noise power density ratio (C/N0), platform dynamics, and differing Inertial Measurement Unit (IMU) quality affect the performance of Deeply Integrated (DI) algorithms. Two different DI algorithms are described in detail and analyzed using a high fidelity GPS simulator. The first algorithm is a Vector Delay/Frequency Lock Loop (VDFLL). The second algorithm is a Deeply Integrated GPS/INS system with differing grades of IMUpsilas. The ability of the algorithms to operate at low C/N0 levels and in high dynamics is investigated empirically with the GPS simulator. The VDFLL algorithm can successfully track the received GPS signals through 2 g, 4 g, and 8 g coordinated turns at 19 dB-Hz. Initial results of the Deeply Integrated GPS/INS algorithm show its operation through the 2 g, 4 g, and 8 g coordinated turn at 16 dB-Hz with a tactical grade IMU.
