Abstract

An electronic speed detection system is provided. The electronic speed detection system includes an accelerometer coupled to a moving object and a hybrid altimeter, which includes a first pressure sensor coupled to the moving object and a second pressure sensor. The electronic speed detection system also includes a controller comprising a memory and a processor. The memory storing computer program instructions executable by the processor to cause the electronic speed detection system to determine a normalized position based on first inputs received from the hybrid altimeter, or determine a corrected velocity position based on a second input received from the accelerometer and the normalized position.
