Enter thebarometric altimeter, which is supposed to solve this. Atmospheric pressure drops as you gain altitude, allowing the change in elevation to be calculated. Unsurprisingly though, barometric altimeters are affected by changes in the weather, such as when a low or high pressure system moves ...
which uses a complementary filter air / GPS integration of highly complementary channel filtering to eliminate severe pressure altitude value change; Kalman filtering through the establishment of barometric altimeter / GPS / inertial navigation system integrated navigation system state equation and measurement...
Improving GPS-Based Landing System Performance using an Empirical Barometric Altimeter Confidence Bound. This paper develops an empirical confidence bound for barometric altimeter altitude errors and shows how this bound may improve the performance of GPS-base... Shau-Shiun,Jan,Gebre-Egziabher,... ...
Other features include an electronic compass, accelerometer, and barometric altimeter to help you track direction while standing still and chart your elevation gain and loss throughout the hike. The Oregon 700 is also capable of being used for navigating on the water and getting turn-by-turn driv...
Barometer/altimeter:While all GPS receivers can tell you altitude based on satellite data, a unit with the barometer/altimeter feature provides more accurate elevation readings by also considering barometric data. This feature also lets you gauge weather trends. ...

Luckily, every GPS on our list includes at least a basic barometric altimeter system. Compass While no piece of technology should ever replace a compass that can run without batteries in your kit, every GPS in our guide will also help you always point north. ...
On units that have the barometric altimeter, do you have a choice as to which to use? Is averaging with GPS altitude done? Elevations are used in disc golf to determine the effective length to a basket. The guideline used is for every 10 feet of elevation change the distance is changed...
1. Use GPS altitude. This method correlates the measured local barometric pressure with the altitude measured by GPS. This method can be used when your device has a clear line of sight to the sky and a reliable GPS fix with good accuracy. ...
Barometric Altimeter If summit hiking is your thing, this is a significant feature to consider since this will provide you with more accurate elevation readings. Some units are capable of measuring only the altitude while units that feature the barometric altimeter help you to forecast weather trends...
