WebSep 11, 2024 · BLOS, beyond NLOS. Beyond-line-of-sight (BLOS) propagation is a special case of NLOS often encountered in very long-distance communication links blocked by earth bulge, terrain, or other obstructions. BLOS and NLOS are virtually identical conditions with BLOS being used by the military to describe much the same conditions as NLOS. WebThe size of an equatorial bulge depends on the inverse of a planet’s density, and the square of its rotation speed. The average density of the earth is 4.15 times as great as that of Jupiter. Also Jupiter rotates once in 9.9 hours. (24/9.9) ² = 5.87, multiply that by 4.15 = 24.4.
