GPS-Tacho is a speedometer based on the values of your GPS sensors. It is displaying speed, precise GPS-time, coordinates, altitude, a compass with bearing and, if a data connection available, the current address.
A special optional item for car drivers: the background color changes at common speed limits:
50 km/h, 70 km/h, 80 km/h, 100 km/h, 120 km/h.
Unreliable speed values are now shaded in gray (eg. if the sensor is indicating a low speed, but no location change is detected).
Selectable speed output formats: m/s, km/h, mph, kt
Selectable distance and altitude formats: km, Nm, m, ft, yd
Different degree out formats selectable.
GPS-Tacho also provides trip statistics with maximal speed, duration, odometer, average total speed, moving time and average speed when moving, ascend and descend sum. Please respect, that altitude values from GPS have onlay one third accuracy compared ot horizontal coordinates!
Your can also get high precision averaged GPS coordinates to reduce GPS error eg for placing geocaches.
Averaging and trip statistics now run in a separate service, ensuring not to be terminated if app is running in background.
You can save a location as GPX file on your sd-card.
For raw positioning network based localization is supported (internet access necessary), but coordinate averaging and trip statistics require GPS. Please keep in mind, that the GPS sensors require high battery power. Although there are several power saving options in the settings, an expernal power supply is recommended for longer measurements.
