The average altitude of the station orbit rose by 2.8 km and amounts to 411.7 km.
After completion of reboost maneuver the ISS orbit parameters are as follows:
- minimal altitude over the Earth – 408.4 km;
- maximal altitude over the Earth – 426.7 km;
- orbital period – 92.743 minutes;
- inclination – 51,66 degrees.
The purpose of the maneuver was to create an operational orbit required to support Soyuz TMA-07M undocking and re-entry on May 14, 2013 and mission of Soyuz TMA-09M that will be launched on May 29, 2013.
