The MaexPro model is shown to calculate adequately ε(λ) and concentration of sea salt aerosol (SSA) particles for different wind regimes, fetches, and humidity. The calculated ε(λ) profiles well agree with experimental data and with calculations using ANAM code. The results thus obtained give a new explanation for the effect of decreasing transparency, manifested in coastal zone, and make it possible to account for indirectly the type (marine or coastal) of air mass.
The field studies show that, for chosen conditions of measurements and types of laser beams, the contrast of brightness depends strongly on beam type.
We discuss the issues of precision of TNS-guided course setting and possibilities for TNS and GLONASS/GPS system coupling using digital navigation maps with the ship coordinate determination simultaneously in two independent channels, thus making the ship navigation much more reliable and safe. A key salient feature of TNS is that the ship can be navigated within the line of sight at distances as long as 20 km at up to 1-m SD of cross-track deviation from preset course, and those observations are ensured under the conditions of degraded visibility in the atmosphere.
Capabilities of “Vzlet” TNS are explored for aircraft taxiing, take-off, and landing on the basis of preliminary flight tests. Other potential TNS applications are discussed.
