WebThe critical orbital features for a Molniya orbit are a = 26, 564 km (i.e., the period is about 12 h), e = 0.7411, i = 63. 4 ∘, and ω = − 9 0 ∘ (perigee in southern hemisphere). The argument of perigee must be − 9 0 ∘ so that the Molniya apogee is at the highest possible northern latitude for good observation of Russia. WebNov 1, 2011 · It has been previously shown that the two-satellite system on a Molniya-type highly elliptical orbit (HEO) with a 12-h period can provide continuous observations of the Arctic region above approximately 58° and 38°N for the maximum viewing zenith angles of 70° and 90°, respectively ( Trishchenko and Garand 2011 ). Originally called the Molniya-2M, their development began in 1972, with launches from 1974. They were also based on the KAUR-2 bus, launching solely from Plesetsk. Earlier models were used for civilian communications in a similar orbit, but different purpose, to the military-only Molniya-1 satellites. From 1980s they were used by the military, and by the 1990s they were operated in the same manner as the Molniya 1 satellites. meatless kentucky fried chicken
