International Space Station reboosts
This page is periodically updated with data about the ISS reboosts.
For reboosts until 2021-01-21, the data taken from
spaceflight.nasa.gov
are also shown (page no longer available).
Starting from 2021-03-12, the data taken from
nasa-public-data
are used to create this graph. It shows:
- the radius vector minus 6371 km (just to show an approximate altitude) and the orbital speed before and after the reboost;
- two vertical green lines representing the start and end of the reboost;
- four points showing the semi-major axis (or mean radius vector) minus 6371 km and mean orbital speed of the last and penultimate orbit before the reboost and the first and second orbit after the reboost;
- four dashed horizontal lines representing the mean radius vector - 6371 km and mean orbital speed of the last two orbits before the reboost and the first two orbits after the reboost.
This graph shows the instantaneous radius vector for 1 orbit before the reboost (blue solid plot) and after the reboost (orange solid plot).
The two dashed lines represent the mean radius vector (or the semi-major axis).
With the help of this graph, we can calculate the variation of the semi-major axis and the variation of the apogee and perigee radius vector.

If we consider these two TLEs (19082.36613198 and 19083.2165162), we see +1.8 km for the perigee, +1.2 km for the semi-major axis and +400 m for the apogee.

Another "big" perigee-only reboost that increased the semi-major axis of about 1.6 km.
The graph shows a ΔV of about 0.9 m/s.
The graph shows that the reboost raised the perigee of about 3.25 km.
If we consider these two TLEs (19057.11380787 and 19057.52041069), we see +3.3 km for the perigee and +1.6 km for the semi-major axis; the apogee is untouched.

This "big" perigee-only reboost increased the semi-major axis of about 1.7 km.
The graph shows a ΔV of about 0.99 m/s.
The graph shows that the reboost raised the perigee of about 3.4 km.
If we consider these two TLEs (19018.54061617 and 19019.44296344), we see exactly +3.5 km for the perigee and +1.72 km for the semi-major axis; the apogee is almost untouched.

2.1 ft/s are 0.64 m/s as shown in the graph.
Here is a detailed view of the perigee and apogee radius vector.
The graph shows that the reboost raised only the perigee and not the apogee.
