![]() ![]() Garmin GPS receivers are typically accurate to 10m [horizontalĭid you know that the military did not believe that Einstein's theory of The atmosphere, satellite position inaccuracy and other factors as well - and It turns out to be aboutĭespite the fact that GPS satellites have atomic clocks on board and evenĪfter adjustment for relativistic changes due to speed of travel and distanceĪbove the earth - there are other factors that influence GPS accuracy including Thought GPS was in that category (based on the fact that my satnav shows meĮxactly where I am - but how accurate is that?). We all tend to assume that any system we have is absolutely accurate and I Now, I did a little research on Google and that Little redundant since a GPS system is far more accurate and also gives you Initially it would seem that measuring height using a BMP280 chip is a ![]() Since it uses an SPI interface you can easily connect it to any microcontroller. Outdoor navigation, leisure and sports applications.Indoor navigation (floor detection, elevator detection).In fact the following applications that are suggested by Bosch Sensortech You realise that pressure can also be used to measure altitude. Probably think of this device used only in a weather station environment until Get hold of a breakout board to use it on the bench. It has an insanely small SMD device outline The BMP280 is a barometric pressure sensor with temperatureĬompensation built-in. Of course, you could just use it for weather forecasting!. ![]() So you could measure a rocket's speed and height!.Since you can measure at 157Hz you can use it for rise/sink rate measurement.Can be used to get a better GPS height measurement.so it is useful for dead reckoning height measurement. You can use it for measuring altitude.You can measure pressure using this chip.How about a fast update rate for rise/sink rate You can use it for Weather but whatĪbout Altitude (yes).
