Space Station Orbit Tutorial

FACT 3: There is an approximate repeat of orbit tracks over the same area on the ground every 3 days. Again, the ISS altitude will determine how closely the tracks repeat.

Figure 4. Repeat of orbits every 3 days. Orbits for Day 1 are shown in yellow, day 2 in green, and day 3 in aqua. The first four repeating orbits of the 4th day are shown in red.
