SSC14 VII-7 An Autonomous Proximity Navigation Testbed for Nanosatellites
The goal of this work is to develop techniques and tools to enhance small-spacecraft in-orbit autonomy. The focus is on developing perception and control algorithms to enable autonomous proximity operations, and performing preliminary validation in a laboratory air-bearing testbed. To achieve this, we have developed cubesat engineering models equipped with a simple cold-gas propulsion system, o...
متن کاملReal Time Calibration of Strap-down Three-Axis-Magnetometer for Attitude Estimation
Three-axis-magnetometers (TAMs) are widely utilized as a key component of attitude determination subsystems and as such are considered the corner stone of navigation for low Earth orbiting (LEO) space systems. Precise geomagnetic-based navigation demands accurate calibration of the magnetometers. In this regard, a complete online calibration process of TAM is developed in the current research t...
متن کاملAutomatic Calibration and Visual Servoing for a Robot Navigation System
This paper attacks the problem of automatic location of a mobile robot in an indoor environment. This may be used for calibration to locate the robot accurately before it starts to navigate, or it can be used in visual servoing as feed back to the controller which is maintaining the robot on a course. In this paper, we examine the problem in a special case, where the ground plane is assumed to ...
متن کاملA framework for calibration of electromagnetic surgical navigation system
In this paper, we present a framework of calibrating an electromagnetic backer (Northern Digital's Aurora) using an accurate optical tracker (the Optohak system, also from Notthem Digital). First, registration methods for these two navigation systems are developed. Sub millineter accuracy registration is achieved for both m s . We also address the latency between the two different trackers. The...
متن کاملCalibration of an Inertial Accelerometer using Trained Neural Network by Levenberg-Marquardt Algorithm for Vehicle Navigation
The designing of advanced driver assistance systems and autonomous vehicles needs measurement of dynamical variations of vehicle, such as acceleration, velocity and yaw rate. Designed adaptive controllers to control lateral and longitudinal vehicle dynamics are based on the measured variables. Inertial MEMS-based sensors have some benefits including low price and low consumption that make them ...
