TpSol - your solar time

The main function of TpSol is to give the solar time according to the legal time and the GPS location, but TpSol makes much more:
- It supplies the equation of time and the solar declination
- It indicates the azimuth and the altitude of the Sun
- It draws the shadow of the Sun on a sundial
The sundial can be drawn according to the orientation of the smartphone or the tablet. In this case, TpSol uses a magnetic sensor that it is necessary to calibrate in this way:
- Be sure that no metallic object or magnet is in the surrounding of the device (think to the magnetic lock of the smartphone protection)
- Activate the dynamic drawing of the sundial (button 'Auto' of the group 'Towards')
- Turn slowly the smartphone or the tablet on the three axes: 2 to 3 revolutions during about 10 seconds per axis.
The calibration is finish. The parameters of the sundial orientation (inclination and declination), which are computed and supplied by TpSol from the magnetic sensor, are then less erratic and more accurate. However, the accuracy is not better than some degrees.
