... 8, ``Celestial Mechanics'', 2002 First results of GPS orbit determination with GRAPE package using a square--root information filter M. O. Keshin Institute of Applied Astronomy, St. Petersburg, Russia The zero--differenced carrier phase measurements contain the distance be­ tween the phase centres of receiver and transmitter antennas biased by unknown integer number of cycles (phase ambiguities). ... In the case of GPS the problem of solar radiation pressure modelling is of primary importance. ...

Next: Adaptive filtering from Up: Noise reduction from Previous: The Wiener-like filtering . In the above process, we do not use the information between the wavelet coefficients at different scales. ... At each scale, by changing all the wavelet coefficients of the plane by the estimate value , we get a Hierarchical Wiener Filter. ... We get .

... The third processing stage filters the combined event list to produce the filtered event list, which contains the collection of node-specific exposure maps. ... Combining the event filtering with exposure map construction in one step assures mutual consistency. ... If the original combined event list is missing (as, for example, in the PPS) the original filtered event list is acceptable as a substitute if no changes have been made to the original attitude and housekeeping GTI. ...

... The procedure of radiometer signal integration can be considered as a sort of reducing dimension of the initial sampling space, where the samples are the result of analog-to-digital conversion. ... The probability distribution of the signal and spikes is completely known. ... The quality of the considered algorithm could be also illustrated by Figure 2 . ... One could see the considered adaptive algorithm is preferable even by low degree of compression, because all spikes have been depressed. ...

The SSRT has two independent receiving systems for recording solar observational data, and several ancillary receivers for checking, setting up and adjusting the instrument. The base receiving systen is a multichannel filter receiver for a simultaneous recording in 180 channels with the 500 kHz band each, adjusted at steps of about 600 kHz. ... Channel's band . ...

Nova 1998 2 in M31 this image of the second Nova in M31 in 1998, was made from 38 exposures of 45 seconds integration time. It was made at September 21, 22h 20m UT. Telescope was a CG11 at f/6.3, no filters were used. The long list of processing steps caused the artefacts at the overexposed center of the galaxy and in many of the brighter stars. During the exposures thin clouds covered the sky but the CCD cuts through them, allowing me to obtain this result. ...
