2021/04/08 Nexteq Navigation has launched accelGRx, a platform for accelerating professional-grade GNSS receiver development. The platform provides open and production-ready hardware and software building blocks for GNSS receivers. accelGRx is designed for organizations looking to research and develop new techniques and algorithms requiring deep in-receiver integreation or quickly produce a small, high-performance receiver. accelGRx supports GPS L1 and Beidou B1, and the hardware is GLONASS and Galileo ready. It pairs a compact form factor and industry standard pin layout with a code and phase precision of 4 cm and 0.4 mm respectively for both GPS L1 and Beidou B1. It incorporates an array of software development tools, including the ability to record and play back digitized signals. An accelGRx licensee wil have tools to develop and test new deep in-receiver integration techniques and algorithms: • Access to all source code, logic and tools • Deep in-receiver access to real-time GNSS information • PC-based software model of receiver platform • Store and playback of digitized signals for development and testing • Testing with production-ready receiver and real-world conditions An accelGRx licensee will have the necessary assets and tools to begin commercialization immediately after development is complete: • Hardware design (schematic, PCB layout, and BOM) • FPGA logic design • Full tracking and PVT source code • Receiver operating system • Design documentation and manuals Nexteq also released two other products: matrixRTK is a combination of the PPP and network RTK approaches to benefit network-RTK vendors. matrixRTK has the benefits of network RTK (fast initialization) with the benefit of PPP (no baseline restrictions). L1-RTK-systems is a solution that allows our handheld users to use 2/L1 high sensitive GNSS handhelds working as base and rover to achieve 2-20 cm level accuracy. This is a reliable and cost-effective solution for field workers, Nexteq said.
