Generating a month of ephemeris data at one-second intervals is 2.6 million propagations per satellite. Ok, except SGP4 loses its accuracy over WAY shorter time frames than a month (think hours/days) > Pass prediction over a ground station network might need sub-second precision across weeks. a) sub-second ephemeris for antenna pointing is crazy overkill, and b) same comment about accuracy as above.
