Differential correction vectors for non-Keplerian reference orbits, reexamining rotating ellipses in Hansen type intermediaries
High gain phased array for satellite transmission using feedback to correct phase and amplitude parameters variations
Three nand gate circuits are used to add error detection and reset logic circuitry for initiating and retaining the correct binary state in the flip-flop circuits of a ring counter. As the input signals are counted, the position of the specified state moves in ordered sequence around circuit loop.
Technique determines the effects of losses upon the performance of a birefringent network and shows how the desired amplitude transmittance of the network may be corrected /or predistorted/, prior to synthesizing the birefringent network, to prevent the effects of crystal losses.
