Compass & Altimeter

A simple and easy to use

Compass

to retrieve useful information about your current position such as true

Geographic north

and true

altitude

above sea level.

• Works perfectly

offline

and without network access

•

Geographic north

using magnetic declination

•

True altitude above mean sea level

(AMSL)

•

Sunrise

&

Sunset

times

• Azimut angles in deg, grad, mrad, gon

• Various dials and color themes (including high contrast)

• Angle measurement (with dials including measuring capabilities)

• Bubble Level functionnality (

available in iPhone dial

)

• Use EGM96 as the geoid reference for computing altitude

• Latitude & Longitude in MGRS, UTM coordinate formats

• Latitude & Longitude in DD, DMM or DMS format

• British National Grid (OSGB86) coordinate system

• SwissGrid (CH1903 / LV95 / MN95)

• Magnetic field strength to detect potential perturbations

• Sensor accuracy

• Address of your current location (requires data connectivity)

Compass better works outside where magnetic perturbations are low.

Magnetic closure cell phone cases

may also disrupt the accuracy of the compass.

EGM96

(Earth Gravitational Model) is used as the geoid reference to compute true altitude above sea level from data collected by the GPS sensor.

UTM

(Universal Transverse Mercator) is a system for assigning coordinates to locations on the surface of the Earth.

Have fun !
