1.	What is the line connecting the intersection of the orbital plane with the Earth’s equatorial plane called?(a) Critical point(b) Intersection plane(c) Line of nodes(d) Differential lineThe question was posed to me in semester exam.My enquiry is from Orbital Mechanics and Clock Characteristics topic in division Satellite Radio Navigation& Inertial Navigation of Avionics
Answer» Right OPTION is (c) Line of nodes The best EXPLANATION: The line of nodes is the INTERSECTION of the orbital PLANE with the Earth’s EQUATORIAL plane. The ascending node and the descending node are the points where the satellite crosses the equatorial plane.
