Compass

A magnetic compass with magnetic declination correction for best accuracy. A compass is an instrument used for navigation and orientation that shows direction relative to the geographic North. Geographic North is computed given the magnetic North and the magnetic declination at your current location. In some places around the world, the magnetic North can be as far as 20 degrees from the geographic North.

● Use of GPS or Network location for best accuracy

● Magnetic declination correction

● True altitude above sea level

● Altimeter

● Elevation computation use EGM-96 model

● Supports multiple coordinate formats UTM, DD, DMM, or DMS

● Show Latitude and Longitude

● Sunrise and Sunset times

● Easy calibration

● Show angle in degrees

● Clean design

● Install on SD

● Save places for tracking them

● Create multiple lists of favourite places

● Show shorted path to a place

● Search new places by name or address

● Qibla Compass (find direction of the Kaaba in Mecca)

Place tracking allow you to save your current location for later find its direction from anywhere else in the world!

Note regarding horizontal accuracy:

The device location has an horizontal accuracy that depends on the quality of the GPS signal. The smaller the horizontal accuracy is, the better the location is accurate. In some cases, the horizontal accuracy can be so big that other information can be inaccurate : altitude, distance and direction to a place that is very close to you. Refreshing the location after a few second can give you a better horizontal accuracy.

Note regarding device calibration :

Smartphones use magnetic and orientation sensor in order to compute the direction of the magnetic North. Sensor might be in an unknown state when the application is started. Sensors requires a lot of values to reach optimal accuracy and precision. To do so, move your phone in space in a ∞ figure pattern until the accuracy turns to high.

This application requires permissions in order to compute your location and the magnetic declination for a better accuracy of this compass and to provide you with further information such as true north, true altitude above sea level, direction and distance to any place in the world.

具有磁偏角校正功能的磁罗盘，可实现最佳精度。指南针是用于导航和定向的工具，可显示相对于地理北部的方向。给定您当前位置的磁北和磁偏角，即可计算出地理北。在世界上某些地方，磁性北距地理北距20度。

位置跟踪可让您保存当前位置，以便以后从世界其他任何地方找到其方向！

关于水平精度的注意事项：

设备位置的水平精度取决于GPS信号的质量。水平精度越小，位置精度越好。在某些情况下，水平精度可能会很大，以至于其他信息可能不准确：海拔，距离和到您的位置的方向非常接近。几秒钟后刷新位置可以使您获得更好的水平精度。

有关设备校准的注意事项：

智能手机使用磁性和方向传感器来计算北极的方向。启动应用程序时，传感器可能处于未知状态。传感器需要很多值才能达到最佳精度和精确度。为此，请以∞图形的方式在空间中移动手机，直到精度变高。

此应用程序需要权限才能计算出您的位置和磁偏角，以使该罗盘具有更高的准确性，并为您提供更多信息，例如真实的北方，真实的海拔高度，方向以及到地球上任何地方的距离世界。
