The third-generation Ellipse series has a 64-bit architecture, allowing high-precision signal processing. All of the INS/GNSS devices now embed a dual-frequency, quad-constellation GNSS receiver for centimetric position and higher orientation accuracy. The Ellipse-A is a motion sensor; Ellipse-E provides navigation with an external GNSS receiver; Ellipse-N is a single-antenna RTK GNSS/INS; and Ellipse-D is a dual-antenna RTK GNSS/INS. With its new 64-bit architecture, the third-generation Ellipse series enables the use of high-precision algorithms and technology used in high-end inertial systems such as rejection filters and FIR filtering.

The PNT-6220 Assured Reference combines low-Earth-orbit (LEO) signals, GNSS, terrestrial, wireline and atomic clock services in one small solution for critical infrastructure applications. The PNT-6220 seamlessly combines concurrent L1, L2, L3 and L5 GNSS reception with a LEO-based Satellite Time and Location (STL) timing receiver. It also includes terrestrial receivers and PTP/IEEE-1588 edge grandmaster and PTP/IEEE-1588-slave capability. It provides assured PNT for critical infrastructure applications such as those described in the directives of Presidential Executive Order 13905. It can serve as a timing reference for 5G equipment, an ePRTC-capable reference, or a high-performance disciplined reference that supports PTP/IEEE-1588, STL, RF distribution and multi-frequency GNSS capability. The PNT-6220 can automatically select the most optimal UTC reference input and switch over among its numerous reference inputs if one or more are jammed or spoofed, as well as average several references for additional stability and accuracy.

The AsteRx-m2 Sx OEM board provides a GPS/GNSS receiver with always-on sub-decimeter accuracy without the need for additional correction service subscriptions. GNSS corrections are automatically streamed to the receiver. The integration enables plug-and-play positioning with high accuracy available out of the box. The AsteRx-m2 Sx is an efficient positioning solution for small robots, aerial drones and automation applications. Advanced anti-jamming technology AIM+ ensures robust and reliable operation in challenging environments, even in the presence of RF interference.

The xOEM v3 inertial navigation system includes the architecture from the company’s IP65-encased xNAV v3 as well as a full range of software interfaces, providing integrators maximum configuration flexibility, real-time monitoring, post-processing and analysis. Software interfaces can be customized using the OxTS NAVsuite. Plugins can be created using the company’s NAVsdk, allowing the xOEM v3’s software to be easily packaged and included as part of a product.The high-grade MEMS inertial sensors and real-time kinematic (RTK)-capable GNSS receiver within the xOEM v3 board set deliver high performance capabilities. The board set provides 0.1° heading accuracy, 0.05° pitch/roll accuracy and 2 cm global position accuracy. The board set is compact at 150 grams, which enables manufacturers to seamlessly integrate and build a high-performance INS into their products, such as commercial mapping applications on land and in the air. Its light weight means more payload capacity for other critical components. An add-on lidar georeferencing software package is also available with a sophisticated boresight calibration tool.

The M300 Plus GNSS receiver is designed to supplement the company’s M300 Pro, which is aimed at clients who need a more economical version for their CORS networks. The M300 Plus is also designed for monitoring projects and other applications. By using a powerful, adaptive detecting and canceling technology, the M300 Plus provides enhanced anti-jamming capability, which is critical for a reference station providing reliable GNSS data. Its built-in web server provides remote control of receiver configuration, status, firmware update and data download. It uses a 4G module as an internet backup, enhancing the stability of data connections.

Cesium OSM Buildings expands the company’s suite of Global Base Layers including worldwide terrain, aerial imagery and streetmaps already available. With the new layer, 3D buildings can be visualized, styled and analyzed in an efficient and interoperable manner using 3D Tiles, the open standard developed by Cesium to stream massive 3D geospatial datasets. The layer gives geospatial developers urban context to 3D applications. The buildings are created for efficient visualization and are streamable to any device with 3D Tiles.Cesium OSM Buildings are derived from OpenStreetMap. Buildings are also regularly updated, firmly clamped to terrain, and individually selectable and styleable.

Version 2.1 of Global Mapper Mobile provides updates to both the free and Pro versions. The iOS and Android applications are designed for viewing and collecting GIS data, and provide situational awareness and location intelligence for remote mapping projects. A complement to the desktop version, the mobile app can display all supported vector, raster and elevation data formats. The release improves vector feature styling, terrain layer support and layer transparency setting. In the Pro version, it introduces advanced GPS support, allowing users to connect to external, high-accuracy Bluetooth GPS devices from vendors such as Eos Positioning and Bad Elf. It also allows access to detailed information including the satellite constellation, precise location information and the raw NMEA stream.

The Xeno FX is a fixed-wing platform optimized for efficient and cost-effective area survey and monitoring missions. Users can program the flight plan before launch to ensure thorough coverage of a target region. The fixed-wing design allows for efficient cruise and maximum time aloft. The Safe Launch protective feature means the propeller starts spinning only after the airframe has been safely hand launched. A quick-change modular payload system allows users to reconfigure their data-acquisition hardware for multiple missions. Constructed of Multiplex’s resilient Elapor foam, the folding wings make for compact storage and easy transport.
