Tight Integration Between IMU and GPS for Sounding Rockets, Report no. LiTH-ISY-R-2929

چکیده
This report presents integrity monitoring and integration methods for an Inertial Measurement Unit (imu) and a gps receiver. The methods are applied to data from a Maxus sounding rocket used for microgravity research. It is crucial to determine the rocket position during launch to ensure a safe landing location. Today, the navigation relies on imu integration only. Involving a gps receiver enhances the position accuracy but there is a need for protection against faulty satellite range measurements. Monitoring over a sequence of the measurements gives higher confidence to the tests.

GPS/INS Integration for Vehicle Navigation based on INS Error Analysis in Kalman Filtering
The Global Positioning System (GPS) and an Inertial Navigation System (INS) are two basic navigation systems. Due to their complementary characters in many aspects, a GPS/INS integrated navigation system has been a hot research topic in the recent decade. The Micro Electrical Mechanical Sensors (MEMS) successfully solved the problems of price, size and weight with the traditional INS. Therefore...
متن کاملTightly Coupled UWB/IMU Pose Estimation, Report no. LiTH-ISY-R-2913
In this paper we propose a 6DOF tracking system combining UltraWideband measurements with low-cost MEMS inertial measurements. A tightly coupled system is developed which estimates position as well as orientation of the sensor-unit while being reliable in case of multipath e ects and NLOS conditions. The experimental results show robust and continuous tracking in a realistic indoor positioning ...
متن کاملA New Algorithm for Calibrating a Combined Camera and IMU Sensor Unit, Report no. LiTH-ISY-R-2858
This paper is concerned with the problem of estimating the relative translation and orientation between an inertial measurement unit and a camera which are rigidly connected. The key is to realise that this problem is in fact an instance of a standard problem within the area of system identi cation, referred to as a gray-box problem. We propose a new algorithm for estimating the relative transl...

متن کاملEnhancing the Performance of Ultra-Tight Integration of GPS/PL/INS: A Federated Filter Approach
The integration of GPS, PL and INS sensors can be implemented at three different levels. Compared with loose and tight integration, ultra-tight integration offers numerous advantages including increased robustness under high dynamics, and improved antijamming performance. In current ultra-tight integration scenarios, a centralised Kalman filter is commonly employed to fuse either In-phase (I) a...
