Product Overview
RB3 GNSS Box Receiver
RTK GNSS Receiver | Dual-Antenna Heading | 544 Channels | Integrated 4G / UHF / WiFi | IP67 Rugged
The RB3 GNSS Box Receiver — powered by Septentrio AsteRx M3 Pro+ — is a high-precision, multi-constellation RTK GNSS receiver and heading system designed for the most demanding professional positioning environments. Featuring 544 tracking channels, full support for GPS, GLONASS, BeiDou, Galileo, QZSS, SBAS, and an integrated L-band receiver, the RB3 guarantees maximum satellite visibility and signal continuity across all geographic regions and terrain types.
The RB3 delivers RTK horizontal accuracy of 0.6 cm + 0.5 ppm and RTK vertical accuracy of 1 cm + 1 ppm, making it one of the most precise GNSS receivers available for field professionals. The dual-antenna design provides real-time heading output with orientation accuracy of 0.03° at 5-meter antenna spacing and 0.15° at 1-meter spacing — eliminating the need for a magnetic compass in UAV, machine control, and autonomous navigation applications.
Unlike standalone GNSS modules, the RB3 integrates a complete field-ready communication suite: 4G LTE full-netcom connectivity, a UHF radio transceiver (410–470 MHz, 1W TX power), 802.11b/g WiFi, Bluetooth 5.0 with EDR downward compatibility, and 100M Ethernet — all in one IP67-rated enclosure that withstands -40°C to +80°C operating temperatures, 100% anti-condensing humidity, and 1.5-meter free-drop impact resistance.
Running on a Linux A7 operating system, the RB3 supports advanced network management including NTRIP Caster/Server/Client, VPN, OpenVPN, intranet penetration, dynamic domain names, and remote web-based configuration — making it equally suited for permanent reference station deployment and mobile field operations. Internal 32GB storage records data in NMEA 0183, RTCM V2.x/V3.x, Rinex v3.04/v2.11, and ROX formats, with support for simultaneous network transmission of 2–4 data streams.
