Challenges and opportunities for satellite communications and navigation augmentation systems in maritime non-exclusive VHF bands

The VHF Data Exchange System (VDES) is a future maritime communication system with the principal objective of enhancing maritime communication applications, based on robust and efficient digital transmission with wider bandwidth than Automatic Identification System (AIS), with a data rate up to 32 times the current AIS. As for AIS, VDES is mainly a ship-to-ship and ship-to-shore system. The ship-to-shore system will use the terrestrial VDES infrastructure that will extend the VDES coverage to only around 60 km from the shore.

Feasibility of ultra low thrust transfers in L1, L2, Sun, Earth & Moon Systems

The number of spacecraft flying in highly nonlinear gravitational fields is largely increased during the last few decades, and probes orbiting in Lissajous or Halo orbits can be found around both the Lagrangian Points L1 and L2 of the Sun-Earth&Moon system.
