mosaic-X5 is a surface-mount GNSS receiver module for precise positioning in autonomous systems. It supports multi-band satellite tracking, RTK processing and a 100 Hz update rate, with onboard interference mitigation and spoofing-protection functions.
The mosaic-X5 is a multi-band, multi-constellation GNSS receiver module made by Septentrio. It is a surface-mount land grid array package that gives centimeter-level RTK positioning to robots, autonomous vehicles, logistics equipment and unmanned aircraft, and it can be integrated into inertial navigation systems as the GNSS source.
The receiver has 448 hardware channels and tracks all visible satellites at once on GPS L1, L2 and L5 signals, GLONASS L1, L2 and L3, Galileo E1, E5a, E5b, E5 AltBOC and E6, BeiDou B1, B2 and B3, QZSS, NavIC L5 and SBAS services, with an on-module L-band input. Tracking all constellations and frequencies improves availability in obstructed areas and speeds up convergence. In RTK mode the accuracy is 0.6 cm + 0.5 ppm horizontally and 1 cm + 1 ppm vertically, with an initialization time of 7 s. Standalone accuracy is 1.2 m horizontally and 1.9 m vertically, and velocity accuracy is 3 cm/s.
The maximum update rate is 100 Hz for position and measurements, with latency under 10 ms, which suits flight control loops that consume GNSS data at a high rate. Cold start time to first fix is under 45 s, warm start under 20 s and re-acquisition 1 s. The PPS output has a time precision of 5 ns. The receiver operates in both base and rover roles and supports moving-base RTK. It is a single-antenna receiver without dual-antenna heading.
Interference handling is a key feature for unmanned systems. AIM+ monitors and mitigates narrowband and wideband interference, including chirp jammers, and provides anti-spoofing protection, with OSNMA support. LOCK+ keeps tracking under shocks and vibration, APME+ reduces multipath, IONO+ limits the effect of ionospheric disturbances and RAIM+ monitors integrity.
For integration, the module measures 31 x 31 x 4 mm and weighs 6.8 g. It runs from a 3.3 VDC supply, drawing 0.6 W typically and 1.1 W at most, and operates from -40 degrees C to +85 degrees C. The interfaces are four UARTs (LVTTL, up to 4 Mbps), a 10/100 Mbps Ethernet (RMII/MDIO), a USB 2.0 high-speed device port, SDIO, two programmable GPIO, two event markers and a configurable PPS output. Output protocols include the Septentrio Binary Format, NMEA 0183, RTCM 2.x and 3.x, CMR and RINEX. The antenna input supplies a bias of 3.0 to 5.5 V with a built-in 150 mA current limit. The module is listed with RoHS, WEEE, CE and FCC compliance and is specified for MIL-STD-810G vibration.
Typical applications are robotics, autonomous systems, automation, logistics and port operations, rail and UAV.
Septentrio adds Hoverfly and CUAV as hardware partners for its mosaic-G5 GNSS modules and publishes four open-source reference designs. The additions give drone and robotics developers more ways to integrate the 23 mm by 16 mm receivers.
Septentrio, part of Hexagon, launches the mosaic-G5 P8, a multi-frequency GNSS module of 23 x 16 mm that weighs as little as 2.2 g. It targets UAVs, marine vessels, rail and other mission-critical devices that must keep positioning under…
Shield agrees to buy Echodyne, the Kirkland-based radar maker, in a deal valued at $5.3 billion. The purchase brings software-defined MESA radars, used in counter-UAS systems and for UAS detect-and-avoid, into Shield's Mission Systems…
