mosaic-G5 is a satellite-navigation receiver that processes GNSS signals to determine position and timing. It supplies navigation information to a host installation, with antenna selection and correction services defined by the required positioning performance.
The mosaic-G5 P8 is a multi-frequency, multi-constellation GNSS receiver module from Septentrio, supplied as a surface-mount land grid array package of 22.8 x 16.4 x 2.4 mm and 2.2 g. It determines position, velocity, time and, with two antennas, heading, and it is aimed at mission-critical platforms where an unmanned aircraft must keep a trusted position solution in interference-prone areas.
The receiver has 789 hardware channels and tracks every visible supported signal: GPS L1C/A, L1C, L2C, L2PY and L5; GLONASS L1CA, L2CA, L2P and L3 CDMA; Galileo E1, E5a, E5b, E5 AltBOC and E6; BeiDou B1I, B1C, B2a, B2b, B2I and B3I; QZSS L1C/A, L1 C/B, L2C, L5 and L6; and NavIC L5. Galileo High Accuracy Service and OSNMA are supported, and L-band reception is available on the module in a single-antenna configuration.
The performance figures for an integrator are: RTK accuracy of 0.6 cm + 0.5 ppm horizontal and 1 cm + 1 ppm vertical with a 7 s initialization time, standalone accuracy of 1.2 m horizontal and 1.9 m vertical, and a position update rate of up to 100 Hz with latency below 10 ms. Time to first fix is below 35 s from a cold start and 1 s on reacquisition. With two antennas separated by 1 m, heading accuracy is 0.15 degrees and pitch or roll 0.25 degrees. PPS output precision is 5 ns and event accuracy is below 3 ns.
Resilience functions are central to this variant. AIM+ Ultimate detects and mitigates jamming and spoofing, LOCK+ maintains tracking under high vibration and shock, APME+ reduces multipath, IONO+ protects against ionospheric disturbances and RAIM+ monitors integrity. Authenticated input and output through DTLS is supported.
For integration, the module offers two UARTs (LVTTL, up to 4 Mbps), a USB 2.0 high-speed device port, two programmable GPIO lines, two configurable PPS outputs and two event markers. Protocols are Septentrio Binary Format, NMEA 0183 and RTCM v3.x including MSM. Input voltage is 3.3 V; power consumption is 0.44 W typical with a single antenna and 0.6 W typical with two. The antenna bias is 3.0 to 5.5 V with a 150 mA limit. Operating temperature is -40 to 85 degrees C. The module is CE, FCC, RoHS and WEEE compliant, and is built for high-volume automated assembly. RxTools is the configuration and analysis software.
Typical applications are navigation and timing on unmanned aircraft and other defence, rail, marine and critical-infrastructure systems.
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…
