GPS barometric elevation GPS elevation
GPS elevation calculations can show sudden spikes of considerable errors due to satellites appearing and disappearing. Over a longer period of time satellites provide a reliable elevation reading.
Barometric elevation readings are more accurate instantaneously but can drift towards inaccuracy over longer periods of time because of the changes in barometric pressure during the day and night.
All Garmin handhelds can get a reasonably reliable elevation reading from the satellites. Individual testing has shown a standard deviation of 9.2m over a 12 hour period versus a 7.7m deviation using the barometric elevation sensor. The average error during the periods were GPS 2.6m; barometer 1.9m.
Magnetic compass in GPS
The electronic magnetic compass in any GPS is a convenience feature. A traditional mechanical compass with its magnetic needle is a necessary backup where accuracy is critical.
With the built in magnetic compass in a GPS such as the CSX, you can stand in one spot and have the unit point the correct direction towards a way point.
Without a built in electronic magnetic compass, the user has to start walking to establish the direction towards a way point. In some situations it is simply not possible or safe to move a few metres in order to establish direction.
