     abstract = "{As low-Earth orbit (LEO) satellites are increasingly equipped with
        highly precise Global Navigation Satellite Systems (GNSS)
        receivers, new opportunities for GNSS-based precise orbit
        determination (POD) arise. The availability of GNSS observations
        from satellites that are geometrically well distributed over the
        entire Earth may enable the formation of an independent GNSS
        network in LEO, which can be processed solely on the basis of
        double-difference (DD) observations. This study presents a first
        attempt to compute a network solution of GNSS DD observations in
        space that combines data from eight satellites, including GRACE-
        FO C/D, Sentinel-3A/B, Sentinel-6A and Swarm A/B/C. Using
        satellite laser ranging (SLR) validation, we show that the
        absolute position accuracy of an ambiguity-float network
        solution increases from about 4 cm 1D RMS in a constellation of
        three satellites to about 2 cm--2.5 cm in a constellation of
        eight satellites. Similar results are obtained by comparing the
        baseline lengths from our DD network solution with those derived
        from external ambiguity-fixed zero-difference (ZD) orbits, with
        differences at a level of 2 cm to 3 cm RMS for a network of
        eight satellites. For both the SLR residuals and the baseline
        consistency, an improvement of up to 0.5 cm can be achieved when
        resolving 60 \% to 70 \% of the carrier-phase ambiguities of
        highly dynamic baselines to integer values. Overall, the
        geometric distribution of the satellites and high dynamics of
        the constellation prove to be beneficial for computing a DD
        network solution in space. This is particularly promising in the
        view of large LEO constellations currently being developed, with
        a much higher number of spacecraft and a uniform global
        coverage, where the advantages of the network approach presented
        in this study will become even more significant.}",
