This based on ksp knowledge, so take it with a grain of salt. Typically when you launch a constellation of satellites you want them to all have the same SMA so that they have the same period. Since this one is significantly off it's going to drift relative to the rest of the constellation and isn't likely to provide a useful signal.
The problem is more severe than it may seem. Satellites in the wrong orbit tend to fall to earth sooner (higher partial pressure at lower altitudes). Also, because of the satellites' purpose, they have to reach their design altitude to be of any use at all, for two reasons:
1. Their orbital velocity must agree with the design criteria, so the Special Relativity adjustment in their clock rates will correspond to reality.
2. Their altitude must agree with the General Relativity adjustment made to their clocks, same reason.
If they end up at the wrong altitude, both their velocity and altitude are wrong, and all this deep thinking unravels (and it's not likely that this error can be adjusted for after a launch), as well as the fact that orbital erosion becomes a limiting factor in their lives.
...both satellites are in a safe state, correctly pointing to the sun, properly powered, and fully under control of the ESA-CNES integrated team...ESA teams are investigating the possibilities of exploiting the satellites to maximum advantage, despite their non-nominal injection orbits and within the limited propulsion capabilities. Different scenarios will then be assessed before decisions are taken for a recovery mission
Having been involved in the ground system verification of this system, there are indeed a whole bunch of params that can be tweaked, but these are LARGE anomolies.
