25 de jul. de 2024 · To find the correct antenna type, browse antenna calibrations. Correctly selecting your antenna will help OPUS apply the appropriate antenna calibration model to counter the unique measurement biases inherent in each antenna's design.
14 de jul. de 2024 · The results show that the new method has high calibration accuracy and robustness. The estimation precision of this method is improved by 0.0457°~0.6896° in heading, 0.0125°~0.8072° in roll, and 0.0077°~0.9436° in pitch, compared with that of the conventional angle alignment method.

Hace 3 días · Our VST-based solution is optimized for tests that require high performance in terms of calibration — such as simulating a CRPA antenna, where the channels need to be very tightly synchronized. Photo: M3 Systems
19 de jul. de 2024 · Crowdsourced smartphone GNSS data have the potential to densify existing geodetic-grade GNSS networks, providing valuable observation sources for GNSS meteorology. This study demonstrates high-precision ZTD estimation using crowdsourced smartphone GNSS data.
4 de ago. de 2024 · The Transient Array Radio Telescope (TART) is a low-cost open-source array radio telescope consisting of 24 all-sky GNSS receivers operating at the L1-band (1.575 GHz).
30 de jul. de 2024 · We use the Septentrio PolaNt Choke ring GNSS antenna that supports GNSS signals from many satellite constellations including GPS, GLONASS, Galileo and BeiDou. In this work, we restrict the analysis to GPS but it can easily be generalized to any subset of constellations.
18 de jul. de 2024 · The CentipedeRTK network is a collaborative Global Navigation Satellite System (GNSS) network launched in 2019, consisting mainly of low-cost GNSS receivers and antennas. This network enables free Real-Time Kinematic (RTK) positioning with centimeter accuracy for all users.
