Abstract :
This article describes field test results of hybridization between MEMS inertial measurement unit (IMU) and GPS L1 C/A signal using an ultra-tight coupling (UTC) architecture. A software receiver is used to post-process raw GPS signal and IMU measurement recorded during the field tests. Both indoor and outdoor environments are explored and UTC with MEMS is compared to UTC with high-grade IMU and vectorized GNSS standalone positioning.
