Submersible pilots also rely upon a technique known as inertial navigation, using a system of accelerometers and gyroscopes to track their position and orientation in relation to a known starting point and velocity.

潜水飞行员还依靠一种被称为惯性导航的技术，使用一个由计陀螺仪组成的系统来跟踪们与已知起点相关的位向。

OceanGate's Titan submersible carries a state-of-the-art self-contained inertial navigation system which it combines with an acoustic sensor known as a Doppler Velocity Log to estimate the depth and speed of the vehicle relative to the sea floor.

海洋之门公司的泰坦潜水器携带了最先进的独立惯性导航系统，它结合了一个被称为多普勒日志的声学传感器，以估计潜水器相对于海底的深。
