BatchLSEstimator slowing down with a lot of stations
This is the very special case where each measurement is associated to a different station (i.e. the antenna is on a boat and each measurement is performed from a slightly different location). Of course, no station parameters are estimated in this context.
At the beginning of the BatchLSEstimator estimate method, the construction of the ParameterDriversList using the getMeasurementsParametersDrivers(false) method [line #367 (closed)] can become very slow as the number of measurements, and thus stations, increases. In my case, the complete orbit restitution process takes 1' with 1000 measurements, 10' with 2000 measurements, 1h15' with 4000 measurements, and the loss of performance is entirely due to this initialization, the duration of the estimation itself remains of the same order.
