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.

 

Aeron Systems offers a rugged, high-performance multi-frequency, multi-channel, OCT2, NS7300D-01A, RTK based INS-GPS for military vehicles. Its design is compiled as per the MIL-STD-461F, MIL-STD-810G and JSS55555. It provides centimeter level (0.8 cm, CEP) position accuracy in RTK configuration, 1.5 m (CEP) in standalone mode with L1, L2 and L5 (IRNSS/NavIC) configuration and 1% DT (Distance Travelled) in GPS denied conditions. In addition, the unit also provides the orientation information like roll/pitch angles along with acceleration and angular rate information.

 

It can be utilized for platform stabilization and control application. It is equipped with built-in GNSS receiver, 6-axis high-end tactical IMU, magnetometer and pressure sensor. This IMU-GNSS integrated configurations is designed to handle the poor visibility, multipath, GPS outages and signal jamming conditions. The built-in high performance tactical IMU data is fused with GNSS receiver to provide and seamless real-time navigation information. This is being achieved by Aeron’s proprietary multi-mode EKF parameter estimation engine. The unit can take external odometer input which can be utilized to aid the speed information. The speed information is further used to arrest the position drift in GPS/GNSS outages.

 

The INS-GPS incorporates an RTK based multi-frequency (L1, L2, L5 (IRNSS/NavIC)) to provide high accuracy position data with redundant frequencies and satellite constellations. The OCT2-NS7300D-01A model has a multi-frequency, multi-constellation GNSS receiver with 445 tracked channels and best in class signal sensitivity. The built-in GNSS receivers provide resistance against radio frequency interferences and protects the device from intentional jamming and spoofing. The OCT2-NS7300D-01A provides precise position, orientation, heading and time information in varied operating conditions makes it an ideal chose of military vehicles.

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.

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.
