| Hey all, Want your feedback! We have a way to provide the real-time vertical altitude of a device, accurate to 5 feet, queried through an API. Seems to us that it’d be helpful for drone coordination to continuously adjust AGL and avoid collision. Also so that you'd be able to know a smartphone user's vertical position and take action accordingly. Would this be something interesting to you as developers and drone enthusiasts? If you're curious, here's how it would work To calibrate: - Use API to locate the nearest verified calibration location - Provide the raw barometric reading of your pressure sensor at that location - Receive a corrected barometric pressure - Save the offset and apply it to all future readings for your device At any time after calibration: - Provide your device's pressure sensor's latitude, longitude and corrected barometric reading - Receive absolute altitude and accuracy estimate The API doesn't rely on the barometric formula. It is supported by a network of strategically located reference sensors which would automatically compensate for weather. |
