In March 2021, it was decided to change the typical duration of an LTP from 6 to 3 months, in order to allow Flight Dynamics to produce stable LTP input and to add flexibility by planning LTP closer to the execution dates. The orbit plots still have a six month duration, and the files are named accordinly, but each plot now covers two LTPs.
Additionally the apparent roll angle of the spacecraft with respect to Solar North has been added. This is defined as the angle between the the projection of the solar north rotational pole onto the spacecraft YZ plane and the spacecraft Z axis. This is based on planning files and reflects the current knowledge at the time of plot production.
The Solar Orbiter trajectory is also available as a CDF here

Positions of Remote Sensing Windows
By default, until the Science Working Team has had a chance to refine their positions (typically ~6 months ahead of time), Remote Sensing Windows (RSWs) are placed such that
- they last for 10 days each, and
- are centred in time on the geometric events corresponding to:
- Southern-most heliolatitude (often referred to as "south")
- Northern-most heliolatitude ("north")
Note that if their 10-day default duration means that RSWs can't be centred on these events, then they typically are contiguous and encapsulate these events. This is most commonly the case with the southern-most and perihelion windows.
Importantly, the SWT may decide to adjust the positions and duration of these windows according to the science priorities assigned to each one. Therefore the dates below should be considered provisional where they are more than 6 months in the future. Those RSW start and end dates in blue have already been decided on.
The dates of RSWs (often just indicative) or geometric events in Nominal Mission Phase are:
|Geometric event||Event date||RSW start||RSW end|
