Navisys GE-926B RTK GNSS PCIe Half-Mini Card (u-blox F9P, I-PEX MHF Connector)

The GE-926 is a compact PCI Express Half-Mini Card GNSS module built around the high-performance u-blox NEO-F9P-15B RTK engine. It features an I-PEX MHF RF connector for flexible antenna placement and supports an optional backup battery for faster position fixes.

Designed using the Mini PCIe standard, the GE-926 integrates easily into PC-based or embedded systems, while its half-length form factor makes it suitable for space-constrained designs. In addition to USB, an optional UART/TTL interface is available for versatile system integration.

The module can simultaneously track L1 and L5 signals from all major global navigation systems—GPS, GLONASS, Galileo, BeiDou, QZSS, SBAS—ensuring strong satellite visibility and high-accuracy positioning even in difficult environments.

GE-926 can operate as either an RTK base station or RTK rover, supporting centimeter-level performance. The optional backup battery may be omitted in applications requiring an extended temperature range.
