The zero meridian of longitude

Probability of Reception of Jovian Bursts as Derived from Io-Phase and the Location of Central Meridian Longitude

A radio telescope consisting of a receiver and a dual dipole antenna has been installed at high altitude station Darjeeling to detect solar and Jovian emissions at 20.1 MHz for receiving radio signal from both the Sun and the Jupiter. Signals received during September 2012 are analyzed to compare the Jovian bursts observed in predicted emission phases for the satellite Io of the Jupiter and the...

Animal Navigation: The Longitude Problem

Determining longitude is incredibly difficult--for humans. Are animals fooling us into thinking that they have bicoordinate maps? New experiments show that at least some creatures effortlessly solve the seemingly insoluble problem of longitude.

Improvement of inverting Carrington longitude to corresponding central meridian crossing time: A necessary step to estimate the effect of differential rotation

Latitude and longitude vertical disparities.

The literature on vertical disparity is complicated by the fact that several different definitions of the term "vertical disparity" are in common use, often without a clear statement about which is intended or a widespread appreciation of the properties of the different definitions. Here, we examine two definitions of retinal vertical disparity: elevation-latitude and elevation-longitude dispar...

Animal Navigation: Longitude at Last

Newly hatched sea turtles exposed to artificially generated magnetic fields with parameters characteristic of two sites 3700 km apart, differing only in longitude, can distinguish the two apparent locations and orient appropriately.
