Regular timing observations of the millisecond pulsar PSR 1937+21 at a frequency of 610 MHz by means of the TNA-1500 radio telescope with a fully steerable 64-m antenna have begun at the Bear Lakes Radio Observatory of the Special Research Bureau of the Moscow Power Engineering Institute. A 40-channel spectrum analyzer and a system for high-speed recording and acquisition of observation data are connected to a reference clock by means of CAMAC interfaces and an 80286 control computer. The reception band is 1.6 MHz (40 channels of 40 kHz each). The total noise temperature of the system is on the order of 160 K. The signal-to-noise ratio is on the order of 50 for a 30-min observation of the pulsar. The mean-square error of measurement of the pulse arrival time is 400 nsec. Data on pulsar 1937+21 along with timing results for “normal” reference pulsars PSR 0834+06 and PSR 1919+21 obtained at the Pushino Radio Observatory of the Lebedev Physics Institute over a period of 13 years will be used to construct a pulsar time scale.
