Research output: Contribution to journalArticlepeer-review


The line-of-sight visibilities between each Martian moon and Earth, including two possible ground site locations on each of the moons was studied. Each of these location was examined for unobstructed visibility and an obstructed viewing case with a 10-degree reduction in viewing all around. The line-of-sight results for each moon were then combined to determine the overall line-of-sight visibility of the system, assuming that beacons are placed on both moons. The results proved greater visibility and redundancy would occur when there are more locations for beacons.
