2. Description of the RadioAstron project, english version
Ground Support of RadioAstron . Control and Tracking Stations . RadioAstron satellite control (command transmission, telemetry, orbit measurements) will be conducted from Evpatoria and Bear Lake control stations. ... Coarse orbit measurements will be carried out from control stations. Each measurement takes ten minutes. ... Orbit measurements at tracking stations give only radial component of spacecraft velocity but the measurements are going continuously during observing sessions. ...

... The MROI makes use of optical interferometry, much like COAST . ... As a major collaborator, the Cambridge Astrophysics Group is currently developing some of the mechanisms below, specifically the delay line and the fast tip-tilt system. ... Fringe tracking is used to control the positions of the delay line trolleys to make sure the light beams from the different telescopes in the MROI arrive at the science camera beam combiners in phase so that an interference pattern can be produced. ...

5. Moving COS FUV Spectra to the Third COS FUV Lifetime Position
... HST . Moving COS FUV Spectra to the Third COS FUV Lifetime Position . ... HST Overview . Overview . ... Sometime near the start of Cycle 22, the location of COS FUV spectra on the detector is expected to be moved from the second COS FUV Lifetime Position (LP2) to the third COS FUV Lifetime Position (LP3). ... With the LP3 move, spectra will be shifted below the original LP1 position by about -2.5", which maximizes resolution and the detector area available for future lifetime positions. ...

12. Description
... Meta Index / Home Page The eposcorr task reads the X-ray source positions from an input fits-file and correlates those with the positions from an optical source catalogue. The correlation algorithm checks whether there are offsets in RA and DEC which optimize the correlation. ... If demanded a similar grid search is done for roll angle errors. ... The optimum offsets are then used to correct the input source positions which will be added as seperate columns to input X-ray source catalogue. ...

15. Linux I/O port programming mini-HOWTO: High-resolution timing
... First of all, I should say that you cannot guarantee user-mode processes to have exact control of timing because of the multi-tasking nature of Linux. ... However, for most applications using I/O ports, this does not really matter. To minimise this, you may want to nice your process to a high-priority value (see the nice(2) manual page) or use real-time scheduling (see below). ... Linux 2.x kernels have soft real time support; see the manual page for sched_setscheduler(2) for details. ...
