The quest Last Voyage will lead you to a poseidon radar transmitter, which is a miscellaneous item.
It is a piece of equipment that the player needs to repair the guidance radar on the U.S.S. Constitution on the last voyage of this ship. After reaching 250 Cap, Mr. Navigator can give this mission to the Sole Survivor.
Military Radar Bands: KuRFS - Counter-UAS Defense (Ku band)
The Ku radar, designed in partnership with Raytheon Missiles & Defense, is tailor-made to defeat rocket, artillery and mortar, or RAM, attacks in the wars in Afghanistan and Iraq. Ku radar's shorter wavelengths, which are wider than military radar frequencies, produce a significantly sharper picture resolution. They can distinguish between a 9mm bullet (or a small number of clutter) and the radar.

According to Will Strauss at Raytheon Missiles & Defense Technology Director for short- to medium-range ground based air defense programs, Ku radar's low powered operation makes it ideal in stand-off missions.
Williams claims that the Ku radar can pick up small unmanned aerial vehicles (UAVs) up to six miles away, despite its small size. Strauss claims that Ku radar is extremely versatile because it consumes very little power. It can also be deployed to serve as sentry on one-ships and in distributed arrangements.
Jason-1 Altimeter Earth’s Ocean Surface Topography. Climate Research
Jason-1, which was launched in December 2001 by NASA/French space agency CNES, is a follow-up mission to TOPEX/Poseidon. Its purpose is to maintain an invaluable ocean topography data records on the primary track. It flew in precisely coordinated orbits with TOPEX/Poseidon during portions of its mission. This cross-calibrated both satellites and increased their data coverage.
This has led to an unbroken, unprecedented climate record of sea-level changes over all ocean basins for 20+ years. It also helped us understand ocean circulation better.

However, this instrument has some limitations. However, this instrument does not have the ability to detect eddies or rings.
The Jason-1 altimeter, which is smaller than other comparable instruments, is not capable of measuring ice thickness, or other oceanic parameters, that would require a larger spacecraft. However, it does provide important data that can be used to study the climate and sea ice and other oceanic phenomena.
Another unique characteristic of the satellite's ability to measure atmospheric concentration is its ability. This is because the satellites used for the mission, called JMR and DORIS, are designed with ionospheric correction in mind. This is essential to ensure that satellite's measurements are properly integrated with other satellites in SeaWiFS' network. This is essential for research and for laying the foundations of an operational system.
