Scientific paper

Considerably clearer pictures from Mariner 10 in its encounter with the planet Mercury could be obtained because of an improvement of 0.82 dB in the signal-to-noise ratio. This improvement was made possible by the use of a newly developed signal combiner that coherently phases and sums the real time telemetry data received simultaneously by three tracking stations. By means of this new approach the bit error rate could be reduced from 4.7 errors/100 bits for 3.3 errors/100 bits.
