Rugged RTK Based Multi-Frequency INS-GPS/GNSS For Military Vehicles

Rugged RTK Based Multi-Frequency INS-GPS/GNSS For Military Vehicles The military vehicles are being extensively utilized for movement of troops, fuel, and transportation of military assets for various strategic missions by defence forces. These vehicles provide superior protections for passengers and military assets. In addition, large section of military operations uses armoured vehicles to counter the enemy attacks. The operating conditions of these vehicles are mostly remote with almost no physical means of referencing available for larger sections of the region. It enables the use of GPS/GNSS based navigation system to know position (Latitude, Longitude and Time) information of a vehicles to follow the desired path.

 

The real-time location information during operations is a crucial input for Battlefield Management (BMS) systems. The BMS makes use of the GPS/GNSS data (Position Navigation and Timing) integrated with GIS to strategically manage the battlefield situations to support a better coordinated decision on field with optimum accuracy. In basic configuration, GNSS comes with single frequency (L1), supporting GPS, GLONASS and Galileo satellite constellations. The single frequency receivers are subjected to an inherent error (satellite clock bias, ionospheric/tropospheric perturbations, multipath etc) and provide 2.5 m horizontal accuracies which limits it to be used in precision positioning applications. Such military missions demand higher accuracy systems which gives uninterrupted navigation information in varying operating conditions.

Rugged INS-GPS/GNSS With Multi-Frequency Receiver For Military Vehicles

Rugged RTK Based Multi-Frequency INS-GPS/GNSS For Military Vehicles

Military armoured carriers are extensively used around the World for the movement of troops, fuel, and transportation of military assets for strategic missions. These vehicles provide protection to military personnel and military assets. Military forces readily deploy these armoured vehicles for tactical missions to counter hostilities. The operating scenarios of these vehicles are mostly remote with almost no contact and possibility of external geo-locating. GPS/GNSS based navigation systems are used for real time location (Latitude, Longitude and Time) awareness and to keep on course. The real-time location information during operations is a crucial input for Battlefield Management (BMS) and Blue-force tracking systems. The BMS makes use of the navigation data (Position Navigation and Timing) integrated with GIS to strategically manage the battlefield situations to support better coordinated decisions on field. The GPS position however may be compromised or denied which cannot be afforded in a tactical scenario.

Aeron Systems offers a rugged high-performance Inertial Navigation System model OCT2-NS7300D-01A with multi-frequency (L1/L2/L5), multi-constellation GNSS for military vehicles. Its design adheres to MIL-STD-461F, MIL-STD-810G and JSS55555 standards. The INS system renders better than 1% of DT (Distance Travelled) in GPS denied conditions, centimetre level (0.8 cm, CEP) position accuracy in RTK configuration and 1.5 m (CEP) with SBAS in standalone mode with L1, L2 (GPS/GLONASS/GALILEO/BEIDOU) and L5 (IRNSS/NAVIC) constellations. The INS system also gives reliable ground speed information with and without GPS. In addition, the unit also provides the orientation information, i.e.  heading, roll and pitch angles along with acceleration and angular rate information. Heading is also available in absence of GPS fix with onboard magnetometer. The INS can also be used for platform stabilization and control applications such as Satcom On-the-move. The system comprises of built-in GNSS receiver, 6-axis high-end tactical IMU, magnetometer and barometer sensor.

 

This INS-GNSS system is designed to handle poor GNSS visibility, multipath, GNSS (GPS) outages and signal jamming conditions. The high performance tactical IMU data is fused with GNSS receiver to provide and seamless real-time navigation information. This is achieved by Aeron’s proprietary multi-mode EKF parameter estimation engine. The unit can take external odometer input over Pulse/CAN for speed aiding. With 445 tracked channels, best in class signal sensitivity and resistance against radio frequency interferences and intentional jamming, the OCT2-NS7300D-01A provides precise position, orientation, heading and time information in the remotest and harshest operating conditions making it an ideal chose for military vehicles.
