Current altitude1/9/2023 ![]() When we look at representations of the earth we typically see a perfectly circular sphere. You can then use GPS to fetch the value elevation reading in the DEM. Satellite data from NASA and other public agencies can be combined to create what is called a DEM or Digital Elevation Model which is a detailed list of elevation values for points on the Earth’s surface. In areas with poor GPS reception an altimeter can be more accurate than GPS-based elevation readings and do not require an Internet connection. Modern smartphones contain a barometer that can be used as an altimeter to measure elevation or to calculate the number of steps you have climbed. The bellows then give you an accurate reading of your height above sea level regardless of whether you are on the ground, in a tree, or in an airplane. As you travel upwards, the pressure decreases which causes the bellows inside the barometer to expand. Inside of an altimeter is a barometer which is a device that measures pressure in the air. Altitude is measured with an altimeter by calculating differences in atmospheric pressure. How is elevation calculated? Using an AltimeterĪn altimeter is an instrument used to measure altitude. While elevation is often the preferred term for the height of your current location, altitude and height above sea level are also common. Altitude is a measurement of an object’s height, often referring to your height above the ground (such as in an airplane or a satellite). Elevation typically refers to the height of a point on the earth’s surface, and not in the air. What is elevation?Įlevation is a measurement of height above sea level. From a computer your elevation is loaded from our API based on your location. It will even work when your phone is offline. When viewed from a phone that supports altitude readings, the reading will come directly from your device altitude reading and will update automatically as you move. ![]() Later versions provide two general custom rotations which can be used, Custom 1 and Custom 2, with CUST_1_ROLL/PIT/YAW or CUST_2_ROLL/PIT/YAW angles.This site was designed to help you find the height above sea level of your current location, or any point on Earth. Firmware versions 4.2 and prior can use a CUSTOM (100) rotation to set the COMPASS_CUS_ROLL/PIT/YAW angles for Compass orientation. The label for each option is specified in the order of rotations for that orientation. NOTE: For internal compasses, AHRS_ORIENT is used. For southern hemisphere, switch increase and decrease. Rolling the vehicle upside down should decrease the MagZ value. When set correctly in the northern hemisphere, pointing the nose and right side down should increase the MagX and MagY values respectively. This value will be ignored unless this compass is set as an external compass. The orientation of the first external compass relative to the vehicle frame. ![]() Later versions provide two general custom rotations which can be used, Custom 1 and Custom 2, with CUST_ROT1_ROLL/PIT/YAW or CUST_ROT2_ROLL/PIT/YAW angles.īTN_FUNC1: Button Pin 1 RC Channel function ¶Īuxiliary RC Options function executed on pin changeīTN_FUNC2: Button Pin 2 RC Channel function ¶īTN_FUNC3: Button Pin 3 RC Channel function ¶īTN_FUNC4: Button Pin 4 RC Channel function ¶ Firmware versions 4.2 and prior can use a CUSTOM (100) rotation to set the AHRS_CUSTOM_ROLL/PIT/YAW angles for AHRS orientation. ![]() After changing you will need to re-level your vehicle. This rotates the IMU and compass readings to allow the board to be oriented in your vehicle at any 90 or 45 degree angle.
