The Tactical Embedded series of GNSS/IMUs feature a tactical-grade inertial measurement unit (IMU) and a multi-band GNSS receiver. The line delivers milliradian attitude accuracy and centimeter-level positioning capability in a miniature 15-gram package. The small size enables cost reductions for a range of autonomous pointing and geo-referencing applications such as gimballed intelligence, surveillance and reconnaissance (ISR); satellite communication systems; lidar mapping; and photogrammetry. The line supports external SAASM GPS for defense applications in ISR, electronic warfare, munitions and UAV navigation. The line includes the VN-110E IMU/AHRS, the VN-210E GNSS-aided inertial navigation system (INS), and the VN-310E dual-antenna GNSS/INS.

The CGI-610 GNSS/INS high-precision dual-antenna receiver offers reliable and accurate navigation and positioning for demanding land, marine and aerial applications. The tight fusion of the latest GNSS technology with an industrial-grade MEMS IMU is powered by CHCNAV’s algorithms to deliver accurate hybrid position, attitude and velocity data, even in complex and obstructed environments where GNSS outages can occur. The CGI-610 supports data output up to 100 Hz to meet the requirements of highly dynamic applications such as airplane, train and automobile. An optional external odometer sensor for ground vehicles can provide an additional measurement of displacement and speed, which is fused with the GNSS/INS navigation solution.

The R550 data collector features an industrial-level design and new hardware platform to ensure efficiency and productivity in the field. The IP67 dust-and-waterproof rating protects the R550 from most harsh environments. Equipping it with a 7,000 mA Li-ion battery allows more than 14 hours of continuous operation, while fast-charging technology means four hours for a full charge. The 5-inch-wide sunlight-readable, high-resolution screen provides a smooth experience for any operation. The integrated autofocusing camera helps enhance job documentation by taking photos on site and sharing job information with colleagues. Survey Master field software available on the R550 controller ensures efficient surveys in the field, including topographic surveys, stakeouts, coordinate geometry (COGO) and more. Powered by the Android 8.1 operating system and designed with 4G RAM, 64GB ROM and 4G/BT/Wi-Fi on board, users can run other third-party apps based on their specific requirements.

UAV

OEM board

Provides georeferencing of airborne data

Photo: Applanix

The Trimble AP+ Air OEM solution provides direct georeferencing of airborne sensor data and enables users to accurately and efficiently produce maps and 3D models without the use of ground control points. It is designed for manned platforms, yet small enough for use on UAVs. It is also compatible with airborne remote sensors, including photogrammetric cameras, lidar, hyper- and multi-spectral cameras, and synthetic aperture radar. The Trimble AP+ Air features dual embedded survey-grade GNSS chipsets, an onboard inertial measurement unit (IMU), an external IMU, and the new Applanix IN-Fusion+ GNSS-aided inertial firmware. It is configurable to support the direct georeferencing accuracy demands of low-flying UAVs and high-altitude manned platforms. Trimble AP+ Air is supported by Applanix POSPac MMS post-processing software with CenterPoint RTX post-processing for centimeter-level positioning anywhere in the world without the need for base stations.
