A software GNSS receiver is a specialized form of software-defined radio, implemented as a GNSS receiver. All of our GNSS receiver signal processing downstream of sampling and quantization is performed on a general purpose processor rather than an ASIC or FPGA. In this software-defined approach, one piece of hardware is still needed, the RF front-end. The front-end downmixes, filters, and digitizes the GNSS signal from the satellites and outputs the raw digital stream to the processor. Within the processor, the software-defined GNSS receives and processes the raw stream of GNSS samples to produce a positioning solution. Read here if you’d like to learn more. 

Standard GNSS positioning, also known as standalone positioning, typically provides accuracy in the range of a few meters. RTK, on the other hand, is a differential GNSS technique that provides centimeter-level accuracy. This high level of accuracy makes it suitable for applications that demand greater precision, such as autonomous navigation. 

RTK stands for Real Time Kinematic. This technique includes using a static reference station that communicates with the rover GNSS receiver (I.e., the one onboard your technology) to remove sources of error. This technique enables increased precision in challenging environments such as the urban canyon. We can deploy our own reference base station to our customers or you can plug in with existing reference networks. 

We are commercializing cutting-edge technology that was developed at a university graduate lab. We have since licensed (completed in summer 2023) the technology to bring the power of precise PNT to commercial markets. 

We’re continuously seeking out skilled engineers, innovators, and dynamic sales professionals who share our enthusiasm in providing precise PNT, universally. Please reach out to [email protected] to see current openings.
