The RT3050 Inertial and GPS Navigation System is an advanced six-axis inertial navigation system that incorporates an L1 GPS receiver with an OmniStar decoder board and delivers better than 0.5m CEP positioning under dynamic conditions using OmniStar VBS.

The RT3050 Inertial and GPS Navigation System includes three angular rate sensors (gyros), three servo-grade accelerometers, the GPS receiver and all the required processing in one very compact box. The RT3050 works as a standalone, autonomous unit and requires no user input before it starts operating.

The outputs from the RT3050 Inertial and GPS Navigation System are derived from the measurements of the accelerometers and gyros. Using the inertial sensors for the main outputs gives the RT3050 system a fast update rate (100Hz) and a wide bandwidth. All the outputs are computed in real-time with a very low latency.

The RT3050 Inertial and GPS Navigation System outputs its real-time measurements over CANbus, RS232 and Ethernet. Optional outputs can be made over Analogue.

The internal processing includes the strapdown algorithms (using a WGS-84 earth model), Kalman filtering and in-flight alignment algorithms. The internal Pentium-class processor runs QNX real-time operating system to ensure that the outputs are always delivered on time. The Kalman filter monitors the performance of the system and updates the measurements using GPS. By using the measurements from GPS, the RT3050 system is able to maintain highly accurate measurements and correct its inertial sensor errors.

To obtain measurements accurate to 0.5m, the RT3050 requires a license to use OmniStar VBS. The RT3050 can also use SBAS or Differential GPS.
