North Polar, South Polar, World Maps and Tables of Invariant Magnetic Coordinates for Six Altitudes: 0, 100, 300, 600, 1000, And 3000 Km

摘要

North Polar, South Polar, and World Maps showing constant invariant geomagnetic latitude lines (at 5 degree intervals except for some midlatitude regions) and constant invariant geomagnetic longitude (at 10 degree intervals) are presented for 6 altitudes; 0, 100, 300, 600, 1000 and 3000 km. Tables of data resulting from calculations of geomagnetic field lines which give the locations of even 5 degree intervals of invariant latitude and even 10 degree intervals of invariant longitude are given. The invariant geomagnetic coordinates. The decisions involved in setting up the invariant longitude system and the special features used in the design of the maps and tables are described. (Author)
