Trajectory control

It should be noted that this regime allows the possibility that the sensor is spread over several platforms and/or is comprised of several physically different sensors within each platform. It can encompass trajectory control for platforms and even control of data rates in connecting platforms to each other and to a central node. In each case the system can be viewed as consisting of many real or virtual sensors, where a virtual sensor can be a particular mode of a sensor, a position of a platform, a particular bit of a measurement made by a sensor, etc. Thus the sensor management problem may seen in all of these cases as one of choosing to switch between many different sensors, where the choice is made on the basis on knowledge of the environment. This view is schematically represented in Figure 1. 

Applications. To date, the liquid propellant systems used in chemical propulsion range from a small trajectory control thruster with only 0.2 lbf (0.89 N) thrust for orbital station-keeping to large booster rocket engines with over l. 0 million lbf (4.44 MN) thrust. Bipropellant propulsion systems are the most extensively used type today for...

Trajectory control comprises speed control systems that measure a vehicle s average speed over a road section. A vehicle is identified when entering an enforcement section and again when leaving it. The average speed can be calculated by the... 

The voyage corresponds to a discontinnous operation of the system limited to brief periods, some of which are critical in the sense that a failure of the trajectory control leads almost inevitably to the definitive loss of the missioa Consequently, there is a strong need for irrstantaneous availability at critical moments (known in advance). In general, this irtstantaneous availability need does not form an exphdt requirement, but is covered and induced by the need of mission success (reliability). 

Two types of experiments are carried out for tiie subcompartment trapping phaiomena for both water-air (1st year) and woods metal-air (2nd year) these are 1) with deflector plate and 2) without deflector plate. These eiqperiments will provide data base for difiEusion controlled and trajectory controlled entrapment mechanism at various operating conditions. 

C. Information Technology Simultaneously with the previous phases, strategies for autonomous navigation and trajectory control were analyzed and studied. 

Although some experimental results ofnaviga-tion are presented (trajectory control and image processing), these issues will not be discussed in detail in this work because the necessary techniques for this are relatively complex and deserve a unique space to properly discuss this topic.
