SLUGS (Santa Cruz Low-cost Unmanned Aerial Vehicle Guidance, Navigation & Control System) is a platform that includes autopilot software and hardware components that enable a flexible environment for research in GNC applications [32]. The SLUGS was designed primarily for GNC research, and it has already been used in many flight tests. Federal Register Vol. 83, No [FR Doc.

A new method has been developed for predicting and controlling the ground range of an unpowered reusable launch vehicle. The key feature is the use of the quasi-equilibrium glide condition to create a database of range-to-go versus energy for different values of the glide-efficiency factor.

The real median value of the distance between the circular trajectories obtained from the GPS RTK in the center of the boom was m, with a standard deviation of m and a minimum-maximum range of variation of m– m.

The vehicle control system processes the planned trajectory and determines a set of control actions (e.g., steering, braking, accelerations) to perform over time to cause the vehicle to maneuver along the planned trajectory.

As the vehicle maneuvers along a planned trajectory, it may arrive at each of the waypoints identified in the planned Cited by: 4. [The AGS is the Abort Guidance System, the backup navigation system used primarily for an emergency return to orbit.

The Primary Guidance and Navigation System provides more information and will be used during the landing. The two systems are cross-checked prior to descent; and close agreement between them gives confidence in both.].

Simple Missile Ballistics, Orbits and Aerodynamics: Trajectory: the direction and speed of a projectile such as a cruise missile or a spacecraft in flight requires the addition of a guidance control system to provide a reference direction and a means of keeping it on track.

Thus it needs an on board power source and a means of changing the. The text studies trajectories, zones of interception, the required manoeuvre effort, time of flight, launch envelopes, and stability of the guidance process.

Mathematics at first-year university level is the only prerequisite. Acquaintance with feedback control theory would be helpful to the reader.

A Mars cycler (or Earth–Mars cycler) is a kind of spacecraft trajectory that encounters Earth and Mars regularly.

The term Mars cycler may also refer to a spacecraft on a Mars cycler trajectory. The Aldrin cycler is an example of a Mars cycler. Cyclers are potentially useful for transporting people or materials between those bodies using minimal propellant (relying on gravity-assist.

The different design groups must work together to produce the most efficient weapon in terms of high accuracy and low cost. The intent of this book is to present the fundamental concepts of guided missiles, both tactical, and strategic and the guidance, control, and instrumentation needed to acquire a target.

Chapter 2 LATERAL VEHICLE DYNAMICS The first section in this chapter provides a review of several types of lateral control systems that are currently under development by automotive manufacturers and researchers.

The rapid developments of Artificial Intelligence in the last decade are influencing Aerospace Engineering to a great extent and research in this context is proliferating. Journal of Guidance, Control and Dynamics, 40 (7), DOI: /1.G In this paper a reachability-based approach is adopted to deal with the pursuit-evasion di erential game between one evader and multiple pursuers in the presence of dynamic environmental disturbances (e.g., winds, sea currents).

The Small Scientific Satellite (S 3 or Explorer) was one of the first satellites of this decade. Launched on Novemits mission was to study the earth’s magnetosphere (see Fig.

10). It was a small, spin-stabilized satellite, with a launch mass of approximately 52 kg, and was placed in a highly elliptical orbit of km x 18, km at ° inclination. The composite vehicle is gravity gradient stabilized with the boom In the momentum dump mode, the EPS and RPM are axis nominally along the orbital radius vector and the again caged; the CMG control system operation is the engine of the CSM is in the direction of the flight path.

This layer covers the control of a whole vehicle flow or a partial set of the vehicles, where the grouping is based on either the current location or on the vehicle ownership (fleets).Good example for the location based selection of the vehicle groups is the control of a road cross section or the so called platooning, where an ad-hoc virtual.

This paper deals with the control of lighter-than-air vehicles, more specifically the design of an integrated guidance, navigation and control (GNC) scheme that is capable of navigating an airship through a series of constant-altitude, planar waypoints. Two guidance schemes are introduced, a track-specific guidance law and a proportional navigation guidance law, that provide the Cited by: 6.

guidance and navigation algorithms were developed, and when he drafted what became a text book that documented these principles and saw use in his MIT Astronautical Guidance course.8 It was also during this time period that Battin explored efficient interplanetary transit trajectories.

The major change in the flight control system from Titan II missile to Gemini launch vehicle was substitution of the General Electric Mod IIIG radio guidance system (RGS) and Titan I three-axis reference system for the Titan II inertial guidance system.

Kemal Özgören2 Middle East Technical University,Ankara, Turkey Design of a space launch vehicle is a very challenging and long running activity because of highly complex and interconnected nature of the launch vehicles. Active flow control is the on-demand addition of energy into a boundary layer for maintaining, recovering, or improving vehicle performance.

Since Prandtl’s discovery of the boundary layer, AFC actuation methods have included steady mass transfer via suction or blowing, and unsteady perturbations created by zero net mass flux actuators.

A precision-guided munition (PGM, smart weapon, smart munition, smart bomb) is a guided munition intended to precisely hit a specific target, to minimize collateral damage and increase lethality against intended targets.

Because the damage effects of explosive weapons decrease with distance due to an inverse cube law, even modest improvements in accuracy (hence. OTHER GUIDANCE SYSTEMS. Preset Guidance 10A1. Introduction. In earlier chapters we described guidance systems in which the missile trajectory depends on information received from one or more control points, or from the target itself.

But, under certain conditions, these systems are impractical. This is especially true for long-range missiles. The FSCOORD, along with the G2(S2) and G3(S3), monitors execution of the plan through the-- Div arty S3 for all cannon and rocket systems available to the division.
