Wsn-7 Tech Manual [better] Jun 2026

The AN/WSN-7(V) Ring Laser Gyro Navigator (RLGN) is the U.S. Navy’s standard shipboard inertial navigation system, providing self-contained, GPS-independent position, heading, and velocity data. Detailed in the technical manual, the system utilizes three-axis RLG technology and BITE to achieve 1 nautical mile per 24-hour accuracy.

The WSN-7 is a self-contained . Unlike older "spinning-mass" gyroscopes, it uses three single-axis ring laser gyros and accelerometers to measure the ship’s motion, gravity, and the Earth's rotation. Wsn-7 Tech Manual

The manual provides step-by-step commands to flash a "Blink" example using the JTAG interface (pins 3,5,7,9 on the expansion header). Do not use the USB-to-serial adapter included in the starter kit for production programming; the manual specifies an external Segger J-Link for reliable bulk flashing.

technology. It provides continuous shipboard data on position, heading, and velocity, and it is the primary navigation source when GPS is unavailable. The Next Generation:

The manual details five power modes:

Unlike traditional WSNs that rely on a single MAC layer, the Wsn-7 implements a modular protocol stack configurable via the Wsn-7 Manager software.
