The Viva GNSS iPad App is the perfect tool for all professionals working with precision GNSS systems. The app simulates a Leica Viva series field.
The GNSS-SDR project is the first research-oriented open source Global Navigation Satellite Systems (GNSS) Software Defined Receiver (SDR). Join with us!
Scientific and industrial applications of GNSS signals and data usually require non-standard features of the receiver. Access to intermediate signals is not possible in mass-market receivers, and professional equipment is costly and often a 'black box' that does not offer exact information about how signals are being processed. Since all the processing is done in ASICs, one cannot change the implementation of a certain functional block and assess the impact in the whole receiver performance. We propose the implementation of an open-source GNSS software receiver freely available to the research community. This project provides a common platform for GNSS signal processing and data gathering for scientific applications, testing of algorithms, receiver design, and educational purposes. This tool is intended to foster collaboration, increase awareness, and reduce development costs in the field of GNSS receiver design and customized use of GNSS signals.
