Investigation of GLONASS and Galileo Hybrid Operation for Improved Positioning Precision in Nigeria

Global Navigation Satellite Systems provide positioning, navigation and timing services, but standalone performance in equatorial Nigeria can be affected by satellite geometry, multipath and ionospheric variability. This study compared GLONASS-only, Galileo-only and combined GLONASS-Galileo processing at the LAUTECH GN...

GNSS Antenna Technologies: A Critical Review of Design, Performance, and Emerging Directions for Resilient Positioning, Navigation, and Timing

Global Navigation Satellite Systems (GNSS) now underpin a wide range of positioning, navigation, and timing (PNT) applications, from autonomous vehicles and precision agriculture to critical infrastructure timing and geodetic monitoring. The antenna remains a performance-limiting component in these systems: it determin...

Performance evaluation of GPS and BeiDou hybrid positioning using a low cost GNSS receiver in Nigeria

This study evaluates the performance of Global Positioning System (GPS)-only, BeiDou-only, and hybridized GPS+BeiDou Global Navigation Satellite System (GNSS) constellations in Nigeria, with emphasis on positional stability and the benefits of multi-constellation integration. A dual-frequency u-blox ZED-F9P GNSS receiv...
