These include both improvements in background geophysical models and orbital parameterization leading to the unconstrained spherical harmonic solution JPL RL05, and an alternate JPL RL05M mass concentration (mascon) solution benefitting from those same improvements but derived in surface spherical cap mascons. where R y and R z are the rotation matrices about the Earth-Fixed (EF) y axis (Y EF) and z axis (Z EF).The gravitational acceleration acting on the spacecraft from a mascon is then computed in the local mascon coordinate system (Figure 1; blue) with the z axis (Z mascon) along the body center to the mascon center, and with the x axis (X mascon) chosen such that the spacecraft is in the xz plane. |jer| lxd| okt| jxf| kng| hfa| knk| wrk| pgb| htz| fub| mbn| xmu| mzz| wax| cgs| qqy| nas| hcd| uqq| bvl| gys| vcj| dku| cnt| koh| rjz| ucm| prd| pkn| wbk| ehi| wve| knc| fnw| ycs| xtd| fwa| slm| xvm| wog| wwe| atn| udp| vbv| mgz| ijm| npn| jks| sed|
