A poseidon radio transmitter is a miscellaneous piece that can be found during Last Voyage.
This is an equipment piece that the player must use to fix the U.S.S. guidance radar. Constitution during the last voyage. After the player has reached 250 cap, Mr. Navigator may give the Sole Survivor this mission.
Military Radar Bands: KuRFS - Counter-UAS Defense (Ku band)
Raytheon Missiles & Defense developed the Ku radar. It was specifically designed to defeat rocket, gun, mortar, or RAM attacks during wars in Afghanistan/Iraq. Ku radar's electromagnetic spectrum has a shorter wavelength than most military radar frequencies. This gives the radar a much sharper image and allows it to distinguish between 9 mm bullets and small groups of clutter.

According to Will Strauss of Raytheon Missiles & Defense, technology director for short-and medium-range ground defense programs, Ku radar's low energy operation makes it ideal for standoff missions and to help protect bases from attack.
Williams stated that the Ku radar's small size makes it extremely useful for counter-UAS missions. According to Williams, it can pick out small unmanned aerial vehicle (UAVs), up to six miles from its target. Strauss says that the Ku radar's low power consumption allows it to be deployed on either a single-ship or in distributed configurations.
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 coordinated orbits alongside its predecessor TOPEX/Poseidon for parts of its mission. These orbits cross-calibrated their satellites, and doubled their data coverage.
This unprecedented, 20-plus-year, unbroken climate record has shown sea level changes in all ocean basins over the past 20 years. It also improved our understanding of ocean circulation.

However, the instrument is not without its limitations. The instrument's accuracy is dependent on the distance between the target and the satellite, so it is not very useful for detecting rings or eddies.
Jason-1 is also a small instrument, compared to other similar systems. It is not able measure ice thickness or other parameters of the ocean that would require larger spacecraft. However, it does provide important data that can be used to study the climate and sea ice and other oceanic phenomena.
Another distinctive feature is the ability of the satellite to measure atmospheric electron levels. The JMR and DORIS satellites that were used in the mission are specially designed to correct for ionospheric effects. This is critical to ensure the satellite's measurements can properly be integrated with other satellites of the network, such SeaWiFS. This is critical for operational systems research.
