Abstract: Using a CubeSat-like satellite, we show the lobster-eye (LE) monitor's perspectives and development of an observing plan. This instrument is important because it is able to provide wide-field X-ray imaging. We present the possibilities of monitoring the Galactic center region in the soft X-ray energy (a few keV) bands. The reason is that many X-ray binaries concentrate in the bulge surrounding the center of our Galaxy. Several such binaries are expected to be present in the monitor's field of view (typically a square of about 5 × 5 degrees or more) at the same time. We used the planned LE telescope's 3--6 keV and 6--9 keV band flux. To compare the expected results, we used the data obtained by MAXI/ISS and accommodated these energy bands to assess the object types and their light curves expected to be detected by this LE. We show how such data of GX 5--1 can contribute to this branch.
