It is very unlikely that they had a compass, although some Vikings may have used an instrument called a sun-shadow board to help them to navigate.
这是不太可能，他们有一个指南针，虽然可能有一些海盗使用的一种手段称为太阳阴影委员会来帮助他们来浏览。
But many migrant birds fly only at night and so cannot use the Sun as a compass.
但是，许多迁移鸟类仅在夜间飞行，因此，不能利用太阳作指南针。
Another type of menotaxis is sun compass orientation.
另一种类型的menotaxis是太阳罗盘方向。
Sun Compass is a program to show the north direction from the sun or moon position.
太阳罗盘是一个能依据太阳或月亮的位置指示北方的程序。
Past studies have shown that the insects use the sun as a compass to show them the way.
以往的研究证明这些小昆虫把太阳当作指南针，为它们指路。
Since then, a vast range of species has been shown to use the Sun as a compass.
此后又发现即使在多云天气里蜂照样能找对方向。
James Gould and his colleagues have shown that honeybees make use of at least three different sets of back-up cues in addition to their Sun compass; these include the plane of polarization of light, a magnetic compass and a memory for the Sun`s position at different times on previous days.
詹姆斯。古尔德及其同仁都证实，除了太阳罗经以个，蜜蜂至少利用了三套不同的后备信号，包括光的偏振平面，磁罗盘及对几天前太阳在不同时间的位置的记忆能力。
It is of course very useful for a migrating bird to be able to switch to a magnetic compass when clouds cover the sun; otherwise it would just have to land and wait for the sun to come out again.
具有这种磁场罗盘，对候鸟来说当然非常有用，因为如果乌云遮日，它可以以磁场为向导继续飞行，否则它就只好着陆，等待太阳重新出现。
Wind from the compass points, sun at meridian.
那自四面到临的风，天顶的太阳。
The application of sun compass in the study of PALEOMAGNETISM
太阳罗盘在古地磁研究中的应用
Insect orientation mechanisms mainly include sun compass, magnetic compass, celestial cues, polarized light, compensation for wind drifts and wind orientation.
昆虫的定向机制包括太阳罗盘定向、地磁定向、星空标志定向、偏振光定向、对风漂移的补偿和风定向等。
Tropical sun, exotic animals, atolls-adventure only with a paper plan, compass and my own sketchbook-diary like this graphic
热带阳光、稀有动物、环状珊瑚岛&一次冒险，仅有简单的计划、指南针以及我的素描本，正像这个图形展现的一样
The sun came out, and he succeeded in locating the points of the compass, though he knew now that he was lost.
太阳出来了，他成功地给自己的罗盘定了定方位，虽然他知道自己已经迷路了。
