Add a way to not estimate remote satellite orbit for inter-satellites measurements
For some applications, it is not needed to estimate the coordinates of the remote satellite simultaneously with the ones of the local satellite for inter-satellite measurements. For instance, in LEO satellite orbit determination, remote satellite coordinates can be obtained accurately using IGS products.
Find a way to enable the user to choose whether or not to estimate remote satellite coordinates can be a good enhancement for inter-satellite measurements in Orekit.
