A First Look at the Navigation Design and Analysis for the Orion Exploration Mission 2
نویسندگان
چکیده
ABSTRACT This paper will detail the navigation and dispersion design and analysis of the first Orion crewed mission. The optical navigation measurement model will be described. The vehicle noise includes the residual acceleration from attitude deadbanding, attitude maneuvers, CO2 venting, wastewater venting, ammonia sublimator venting and solar radiation pressure. The maneuver execution errors account for the contribution of accelerometer scale-factor on the accuracy of the maneuver execution. Linear covariance techniques are used to obtain the navigation errors and the trajectory dispersions as well as the DV performance. Particular attention will be paid to the accuracy of the delivery at Earth Entry Interface and at the Lunar Flyby.

The AGV (automated guided vehicle) was introduced in UK in 1953 for transporting. But nowadays, due to their high efficiency, flexibility, reliability, safety and system scalability, they are used in various application in industries. In brief, the AGV robot is a system which typically made up of vehicle chassis, embedded controller, motors, drivers, navigation and collision avoidance sensors, ...
متن کاملA Piloted Orion Flight to a Near-Earth Object: A Feasibility Study
The notion of a piloted mission to a near-Earth object (NEO) was first discussed and analyzed in depth as part of the Space Exploration Initiative in 1989 (Davis et al., 1990). Since then, four other studies have examined the details of sending humans to NEOs (Nash, et al., 1989; Jones, et al., 1994, 2002; Mazanek, et al., 2005). The most recent assessment has been undertaken by the Advanced Pr...

متن کاملNavigation Performance Predictions for the Orion Formation Flying Mission
This paper presents hardware-in-the-loop results that experimentally demonstrate precise relative navigation for true formation flying spacecraft applications. The approach is based on carrier-phase differential GPS, which is an ideal navigation sensor for these missions because it provides a direct measure of the relative positions and velocities of the vehicles in the fleet. In preparation fo...
