 | sat:platform_international_designator | string  | The International Designator, also known as COSPAR ID, and NSSDCA ID                                                                                                                                    |
 | sat:orbit_state                       | string  | The state of the orbit. Either `ascending` or `descending` for polar orbiting satellites, or `geostationary` for geosynchronous satellites                                                              |
+| sat:orbit_cycle                       | integer | The number of repeat cycle done by the satellite at the time of the acquisition. [Repeat cycle](https://ltb.itc.utwente.nl/page/498/concept/81577) is the time between two successive identical orbits. |
 | sat:absolute_orbit                    | integer | The absolute orbit number at the time of acquisition.                                                                                                                                                   |

 | sat:anx_datetime                      | string  | The [Ascending Node](https://en.wikipedia.org/wiki/Orbital_node) Crossing (ANX) time, in UTC. It is formatted according to [RFC 3339, section 5.6](https://tools.ietf.org/html/rfc3339#section-5.6).    |
