For the first time, position fixes in real time using signals from Galileo have been achieved with an open source software receiver. The milestone was achieved by a research team from the Statistical Inference Department here at the Centre Tecnològic de Telecomunicacions de Catalunya (CTTC), which manages the development of the open source project GNSS-SDR. read more

Building a Wide-Band Multi-Constellation Receiver

The authors designed a full-constellation GNSS receiver, using a cost-effective, readily available, flexible front-end, wide enough to capture the frequency from 1555 MHz to 1607 MHz, more than 50MHz. This spectrum width takes into account BeiDou E2, Galileo E1, GPS L1, and GLONASS G1. In the course of their development, the authors used an external OCXO oscillator as the reference clock and reconfigured the platform, developing their own custom wide-band firmware. read more

Testing Software Receivers

December 1, 2009By

To meet the challenges inherent in producing a low-cost, highly CPU-efficient software receiver, the multiple offset post-processing method leverages the unique features of software GNSS receivers to greatly improve the coverage and statistical validity of receiver testing compared to traditional, hardware-based testing setups, in some cases by an order of magnitude or more. read more
