"... We present a reusable software package able to control a large and heterogeneous network of remotely-controlled and robotic astronomical observatories. Special attention was given to the design of a robust, long-term observation scheduler that also allows the trading of observing time and resources ..."

astrophysical missions

by Marcus G. F. Kirsch, Jutta M. Huebner, Jim Martin, Richard T. Southworth, Uwe Weissmann
"... ESA’s high energy astrophysical missions XMM-Newton in the X-ray and INTEGRAL in the gamma ray regime are both operated from ESA’s European Space Operations Centre at Darmstadt, Germany. The designed lifetime and even the extended lifetime have in both cases passed. However both spacecraft with thei ..."

ESAs high energy astrophysical observatories XMM-Newton and INTEGRAL SA is operating within it’s Horizon 2000 programme two major astrophysical

b I Development of a state machine sequencer for the Keck Interferometer: evolution, development & lessons learned using a CASE tool approach

by Leonard J. Redeta, Jonathon Hsieh
"... This paper presents a discussion of the evolution of a sequencer from a simple EPICS (Experimental Physics and Industrial Control System) based sequencer into a complex implementation designed utilizing UML (Unified Modeling Language) methodologies and a CASE (Computer Aided Software Engineering) to ..."

of it to implement the sequencer is presented. The decision to use the Rhapsody product as our CASE tool is explained and reflected upon. Most importantly, a section on lessons learned is presented and the difficulty of integrating CASE tool automatically generated C++ code into a large control system consisting

Assessment of Pseudorange Multipath at Continuous GPS Stations in Mexico

by G Esteban Vázquez , Rick Bennett , Joshua Spinler , 2013
"... ABSTRACT We conducted a study to quantify the amount of pseudorange multipath at continuous Global Positioning System (CGPS) stations in the Mexican territory. These CGPS stations serve as reference stations enabling rapid high-precision three-dimensional positioning capabilities, supporting a numb ..."

A BUOY-BASED WEC DEVICE TO PROVIDE LOW POWER TO SENSORS OMAE2009-80091

by Edward P Davis , R Cengiz Ertekin , H Ronald Riggs
"... ABSTRACT INTRODUCTION Remote ocean instrumentation and monitoring techniques often rely on floating buoys with a variety of sensors to acquire time series measurements such as ambient noise, acoustic tracking or communications. The operating lifetime of small remote buoys is limited by onboard batt ..."

, it is not possible to directly use it in the calculations since the rope winds about the spool mechanism. Electricity is generated only when the buoy-mechanism-box combo moves up, i.e., over one-half of the wave cycle only. One way to model such a physical system is through the use of a viscous dashpot (damper
