Isolines altitude difference and azimuth difference grid of two luminaries in the given longitudinal range
UDC 527 BBK 39.471.4
The article deals with the calculation and construction of isolines of altitude difference and azimuth of two luminaries. It determines the nature of crossing of isolines of altitude difference and azimuth and value gradient of these navigation parameters. It analyzes the conditions of satisfactory and unsatisfactory observation.
Keywords: Isolines, altitude of difference, azimuth of difference, gradient.
