During the equinoxes—both summer and winter—the Sun is directly above the equator, which results in nearly equal day and night lengths across the globe. However, whether a satellite is in sunlight or not depends on its orbit and the time of year.
Satellites in low Earth orbit (LEO) typically experience sunlight even during the equinoxes, as they orbit the Earth quickly (approximately every 90 minutes) and spend part of their orbit in sunlight and part in the Earth's shadow.
On the other hand, satellites in geostationary orbit have a fixed position relative to the Earth’s surface and generally remain in sunlight except during specific alignments with the Earth and Sun, which can cause brief shadowing effects.
Polar-orbiting satellites, which pass over the poles as the Earth rotates, may also enter the Earth's shadow at certain times of the year, depending on the Sun's position.
In summary, while there are times when specific satellites may not receive sunlight due to their orbital characteristics and alignment with the Earth and Sun, this is not generally a function of the equinoxes themselves. Most satellites continuously experience cycles of sunlight and shadow during their orbits.
