“…Additionally, the NASA Goddard Space Flight Center (GSFC) has pioneered work in developing the Navigator, a fully space-flight-qualified receiver with the ability to track very weak terrestrial GPS signals (Winternitz et al, 2004). GSFC is planning to test GPS navigation in the Earth-Moon transfer orbit in 2024 during the Lunar GNSS Receiver Experiment (Parker et al, 2022).…”

After more than 50 years since the Apollo program, there is a growing interest in establishing a sustainable human presence on the Moon. To support increasing plans for lunar exploration, various missions are being planned in different lunar orbit regimes, e.g., the European Space Agency's lunar Pathfinder (Giordano et al., 2022), which is to be deployed in an elliptical lunar frozen orbit (ELFO), and the Lunar Gateway (Winternitz et al., 2019), which is being spearheaded by the National Aeronautics and Space Administration (NASA), in a near-rectilinear halo orbit (NRHO). These missions require precise positioning and onboard timing to

“…Radiometric visibility, which strictly depends on the alignment between the antenna radiation patterns of the receiver and the GNSS satellites, is assessed upon the estimation of the received Carrier-to-Noisedensity ratio (C/N 0 ) from each satellite. This estimation is based on a link-budget model obtained through a highaccuracy fit of the expected C/N 0 levels for the LuGRE receiver throughout the mission [22]. It should be noted that the aforementioned criteria for the synthetic generation of GNSS observables overlook any peculiar conditions for which atmospheric propagation bending may induce radiometric vis-ibility for satellites that are not visible geometrically due to Earth occlusion.…”

“…This assumption finds tangible application in the design of the GNSS receiver involved in the upcoming Lunar GNSS Receiver Experiment (LuGRE) mission. Such a scientific mission is based on a joint NASA-Italian Space Agency (ASI) demonstration payload which will be carried on the Firefly Blue Ghost Mission 1 (BGM1) with the goal of demonstrating multi-GNSS-based PNT in cis-lunar space and at Moon altitudes [22], [23]. The LuGRE GNSS receiver is not expected to interface with the spacecraft GNC subsystem while only relying on GNSS observables and aiding data (i.e., GNSS ephemeris and planned spacecraft trajectory) provided from its ground segment.…”

In recent years, the number of expected missions to the Moon has increased significantly. With limited terrestrial-based infrastructure to support this number of missions, as well as restricted visibility over intended mission areas, there is a need for space navigation system autonomy. Autonomous on-board navigation systems in the lunar environment have been the subject of study by a number of authors. Suggested systems include optical navigation, high-sensitivity Global Navigation Satellite System (GNSS) receivers, and navigation-linked formation flying. This paper studies the interoperable nature and fusion of proposed autonomous navigation systems that are independent of Earth infrastructure, given challenges in distance and visibility. This capability is critically important for safe and resilient mission architectures. The proposed elliptical frozen orbits of lunar navigation satellite systems will be of special interest, investigating the derivation of orbit determination by non-terrestrial sources utilizing celestial observations and inter-satellite links. Potential orbit determination performances around 100 m are demonstrated, highlighting the potential of the approach for future lunar navigation infrastructure.
