099 - Location, Tracking and Salvage support of lost shipping containers at sea
Each year 226 Million container boxes are shipped. About 1600 boxes/year (0,002%) are lost at sea. The boxes are afloat for days to weeks before they are sinking & grounding. The reasons can be traced to top-heavy container stacks (unstable), increasing bad weather (storms) by climate change and time pressure on ship crews (higher on the supply-chains after COVID). The number of boxes lost at sea…
079 - Reduced size Antenna for Earth Pulsar navigation
Pulsar are rapidly rotating neutron stars emitting beams of radiation periodically, some with very high stability.
Since every pulsar has a different frequency, they can be used in a navigation system like beacons, and in timing (see EL1-006).
Emission occurs in all spectrum (infrared, visible, RF, X-ray). For space navigation, detectors in X-ray are preferred for their size, but detectors…
