Price: $1589.00 | Compatible Accessories: Survey GNSS Antenna, 60Pin P2001 Breakout Cable, External IMU For SPAN INS Integration, L-Band Correction Antenna, DC 12V Power Supply; Matching Replacement Model: Legacy OEM628 Pin-to-Pin Drop-In Upgrade

This industrial-grade OEM729 full-spectrum GNSS receiver board solves high-precision positioning bottlenecks for survey & machine control systems: weak satellite signal tracking under tree canopy/urban canyon, electromagnetic interference blocking satellite reception, single-system positioning low reliability, slow RTK ambiguity fixing, lack of INS fusion for SPAN mobile positioning, outdated single-frequency boards unable to track modern BDS/Galileo multi-band signals, and legacy OEM628 hardware performance limitations. Full 555-channel multi-constellation multi-frequency hardware with built-in advanced interference suppression, native RTK/PPP/GLIDE/ALIGN/SPAN positioning algorithms, pin-compatible direct replacement for OEM628 without mechanical enclosure modification, delivers centimeter to millimeter-level stable positioning for deformation monitoring, mining machinery control, hydrographic survey, robotic total station base station and high-precision engineering measurement projects.

Product Overview

The NovAtel OEM729 is a high-performance plug-and-play OEM GNSS positioning board developed by Canada NovAtel, dimension & mounting fully backward compatible with classic OEM628 receiver, designed for industrial high-precision positioning integration scenarios. Complete integrated hardware architecture: dual RF shielded RF receiving modules, 555 universal signal tracking channels, multi-system multi-band RF front-end, built-in anti-jamming filter circuit, multi-channel communication interface controller, SPAN GNSS+INS fusion processing core, external LNA power supply circuit and industrial-grade power management unit. Supports full-band signal reception of GPS, BDS, GLONASS, Galileo, QZSS, NavIC and SBAS satellite constellations, compatible with all modern civil & military multi-frequency navigation signals including BDS B1C/B2a/B3I, Galileo E5 AltBOC, GPS L5/L1C. Equipped with dual SMA RF antenna interfaces (main GNSS antenna + L-band correction antenna for Oceanix PPP service), standard 60Pin P2001 main expansion connector integrating RS232/RS422/LVCMOS UART, USB 2.0, Gigabit Ethernet, PPS time synchronization strobe, IMU data input and DC power port. Built-in enhanced Interference Mitigation technology suppresses construction machinery, high-voltage power line and radio station EMI noise; GLIDE dead reckoning maintains sub-decimeter positioning during short satellite outages, SPAN function realizes high-dynamic centimeter positioning with external IMU inertial sensor. Standard industrial wide temperature PCB coating, independent metal shielding cover, reserved fixed slide rails for vibration-resistant cabinet installation, no firmware modification required for OEM628 equipment upgrade.
