Abstract

The BDA is a synthesis telescope, which consists of 26 parabolic dishes operating in thefrequency range from 1.2 to 1.7 GHz. For calibrating the visibility amplitude and phaseof the interferometric signals it is proposed to use signals from GPS satellites operatingat a fixed frequency of 1575 MHz. Software for the position of GPS satellites and itscalibration will be written in C ++ language. Trial programs on simulation of the above willbe coded to test the validation of the software programs. Also, it is proposed to write thenecessary hypertext markup language (html) programs to post the observed daily solarimages in the INPE website. (AU)
