Attitude Determination Methods Using Pseudolite Signal Phase Measurements
In this paper, new attitude determination algorithms using pseudolite signal phase measurements are developed and presented with realistic simulations. Pseudolite signals are used to replace GPS signals which are often not available due to blocking by nearby large structures, for example a crew return vehicle under the International Space Station. A new observation model needs to be applied bec...
متن کاملAnalysis of Attitude Determination Methods Using GPS Carrier Phase Measurements
If three or more GPS antennas are mounted properly on a platform and differences of GPS signals measurements are collected simultaneously, the baselines vectors between antennas can be determined and the platform orientation defined by these vectors can be calculated. Thus, the prerequisite for attitude determination technique based on GPS is to calculate baselines between antennas to millimete...
متن کاملAttitude Determination of Multirotor Aerial Vehicles Using Camera Vector Measurements
The employment of embedded cameras in navigation and guidance of Unmanned Aerial Vehicles (UAV) has attracted the focus of many academic researches. In particular, for the multirotor UAV, the camera is widely employed for applications performed in indoor environments, where the GNSS signal is often unreliable and electromagnetic interference can be a concern. In the literature, images are mostl...
متن کاملApplication of Network RTK Positions and Geometric Constraints to the Problem of Attitude Determination Using the GPS Carrier Phase Measurements
Nowadays, navigation is an unavoidable fact in military and civil aerial transportations. The Global Positioning System (GPS) is commonly used for computing the orientation or attitude of a moving platform. The relative positions of the GPS antennas are computed using the GPS code and/or phase measurements. To achieve a precise attitude determination, Carrier phase observations of GPS requiring...
متن کاملAttitude Determination using Infrared Earth Horizon Sensors
Infrared Earth horizon sensors (EHS) are capable of providing attitude knowledge for satellites in low-Earth orbit, even during periods of eclipse. Attitude information is acquired by detecting Earth’s infrared electromagnetic radiation and, subsequently, determining the region obscured by Earth in the sensors’ fields of view to compute a nadir vector estimation in the satellite’s body frame. D...
