Since Z vector (in the Antarctic conditions of registering SSR signals) is pointed upwards, it’s changing in the same direction leads to a decrease of SSR density (dDB) and some increase of f. The same effect is observed when the sign of IMF sector is negative (solar wind toward the Sun). It is also when the sensor registers random signals more accurately. When the growth of Z vector is negative (pointed downwards) the density values change controversially (as in case of positive IMF sector). It should be mentioned that the correlation between IMF and TMF components H and Z is predictably negative (-0.2 and -0.19). There is no sufficient evidence of solar radio intensity (SRI, 10.7 cm) and basic solar disturbances (X in the equation of lunar motion) influencing dDB and f. Spectral analysis of the variations in the sensor’s density and reliability values revealed periods which are similar to the periods of SRI variations (51.2, 25.6,28.44 days), Я-15.06 days and IMF (25.6, 28.44 and 15.06 days). Therefore, the similarity of the above-mentioned periods and the presence of correlations between dDB and / variations and variations in gravitational indices of the Sun, the Earth, the Moon and IMF confirm the correspondence of the internal processes in supersensitive sensor with the influence from cosmophysical factors. Here the relatively high correlation of SRI value variations and IMF variations can be attributed to the impact of a gravity-determined IMF- relevant factor onto the screened sensor. In case of the positive IMF sector structure this factor causes increasing of the sensor’s density, which contributes into measuring error. General similarity influencing variations of SSR readings (accuracy of signal presentation) was revealed, which relates to the adequate changes in TMF level and sector sign of IMF. References 1. J.
