LOCAL NAVIGATION IN LUNAR POLAR REGIONS WITH COMPASS, LUNACELL AND MOBILE AD (original) (raw)
2020, 51st Lunar Planetary Science Conference
With the recent expansion of plans for lunar exploration there has been increased interest in support of operations at and near the Moon (i.e., in Cislunar Space), including robotic and crewed missions to the lunar polar regions. Real time navigation and communication will be especially difficult on the heavily shadowed lunar polar regions, given the bad lighting, the frequent lack of line of sight to the Earth, the extreme Geometrical Dilution of Precision (GDOP) for any use of terrestrial GPS and the lack, at least in the near term, of continual overhead satellite coverage. Unlike the Apollo surface Extra-Vehicular Activities (EVAs), future astronauts on polar surface EVAs will need local relays to communicate with the home base, and to perform local navigation, and communication beyond the local line of sight to a central lander.

Low-Cost Lunar Communication and Navigation
energyorbittransferswouldsignificantlylowerthecostofestablishingandmaintaining small lunar communication relay constellations in halo orbits. Autonomous orbit determination would allow the constellation to navigate without expensive Earth-based tracking assets. For libration point orbits, both relative and absolute autonomous orbit determination is possible using only satellite-to-satellite tracking such as crosslink range or Doppler. The spacecraft could be used as mobile tracking stations to provide navigation as well as communications. Low-energy lunar transfers could be used to place more mass into lunar halo orbits than conventional trajectories, and using these low-energy transfers, it should be possible to launch the entire constellation on a single vehicle.
COMPASS Final Report: Lunar Network Satellite-High Rate (LNS-HR)
2012
Two design options were explored to address the requirement to provide lunar piloted missions with continuous communications for outpost and sortie missions. Two unique orbits were assessed, along with the appropriate spacecraft (S/C) to address these requirements. Both constellations (with only two S/C each) provide full time coverage (24 hr/7 d) for a south polar base and also provide continuous 7 day coverage for sorties for specified sites and periodic windows. Thus a two-satellite system can provide full coverage for sorties for selected windows of opportunity without reconfiguring the constellation.
Accessing the Lunar Poles for Human Exploration Missions
2004
The National Vision for Space Exploration calls for an American return to the Moon in preparation for the human exploration of Mars and other destinations. The surface environment of the Moon is a challenge for human operations, but recent findings from robotic and Earth-based studies have indicated that the polar regions of the Moon may offer advantages in terms of thermal conditions, availability of solar energy, and access to local resources. While accessing these regions represents a challenge due to orbital dynamics and propulsive performance, methods for accessing the regions with humans are being actively pursued, and environmental data gathering is planned through future robotic missions.
Establishing a Near Term Lunar Farside Gravity Model via Inexpensive Add-on Navigation Payload
2007
The Space Communications and Navigation, Constellation Integration Project (SCIP) is tasked with defining, developing, deploying and operating an evolving multi-decade communications and navigation (C/N) infrastructure including services and subsystems that will support both robotic and human exploration activities at the Moon. This paper discusses an early far side gravitational mapping service and related telecom subsystem that uses an existing spacecraft (WIND) and the Lunar Reconnaissance Orbiter (LRO) to collect data that would address several needs of the SCIP. An important aspect of such an endeavor is to vastly improve the current lunar gravity model while demonstrating the navigation and stationkeeping of a relay spacecraft. We describe a gravity data acquisition activity and the trajectory design of the relay orbit in an Earth-Moon L2 co-linear libration orbit. Several phases of the transfer from an Earth-Sun to the Earth-Moon region are discussed along with transfers with...
