It is supported by 15 EU member states, including new member states, and thus integrates the entire European optical interferometry community. ...

Operating Instructions PEC Utility Tool For use with Meade LX200GPS and RCX400 Telescopes PEC Utility The PEC Utility Tool allows you greater control over the Periodic Error Correction functions of your LX200GPS or RCX400 telescope. ... PEC Utility option is located in the AutoStar Suite telescope menu and is available with the AutoStar Suite Update, on the meade.com website. ... The "Shifting the PEC" now allows you to shift the corrections forwards or backwards to compensate for the time lag. ...

... In spite of the good potential possibilities, some of the station "Dnepr" design characteristics did not allow us to apply the usual special IS radar measurement methods. ... Thus for IS signal measurements at the "Dnepr" station, we have developed special methods for recording and processing IS signals in order to determine plasma ionospheric parameters. ... Equations (4-5) from the basis for data post processing to obtain ionosphere parameters. ...

Radio Interferometry Principles . Radio Interferometry Signal Processing . ... A radio interferometer consists of a pair of directional antennas that are tuned to receive radio emissions from a source in a desired RF band. ... The antennas are pointed at the radio source of interest and are set up to receive the signal and process it into a form suitable for transmission to the correlator. ... In connected element interferometry, the digital signal goes directly to the correlator. ...
