BSS - Brazilian Solar Spectroscope

BSS, in operation at INPE since 1998, is dedicated to solar spectral observations in decimetric band (200-2500 MHz) with high time (10-1000 ms) and spectral (3 MHz) resolutions. BSS highlights are the flexibility to choose the frequency band and time and frequency resolutions, the acquisition of digital data up to 100 frequency channels, and real time visualization. The absolute time accuracy is <3 ms. Data analysis are done using BSSView software in IDL.

 BDA - Brazilian Decimetric Array

The array consists of 32 low cost parabolic dishes of 4 meter diameter and six antennas of 7 meter diameter. During the first phase it is proposed to construct a "T" array with 21 antennas in an east-west array of about 256 m length and a south array of 11 antennas of about 150 m length. The design of the array is optimized for making two-dimensional maps of the radio Sun at frequencies of 1.4, 2.7 and 5 GHz over a period of seconds or minutes.

MVFR - Milimetric Variable Frequency Receiver

The MVFR is operating at Itapetinga Radio Observatory (ROI), since 1988, within the frequency range of 18-23 GHz, with high spectral (1 GHz) and time (0.6-1.2 s) resolutions. In a near future will operate simultaneously in ~40 GHz. Simultaneous observations in 1-18 GHz, 37 GHz e 87 GHz, permit us to build solar bursts spectrum from 1 up to 87 GHz. The aim is to improve our comprehension about the fundamental questions of solar physics concerning energy storage and its release during solar flares.

SSTomo - Solar Spectral Tomography

In collaboration with the Dept. of Computer Science of UFSCar, is in development a parallel machine for processing, visualization and analysis of tomographic images of solar atmosphere, in real time. The technique of spectral tomography by pattern recognition, will be used for radio and X-ray solar images to characterize large scale solar phenomena with application to space weather forecast.
