Septentrio expands mosaic-G5 integration ecosystem

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, a Hexagon company, enlarges the group of firms that build products on the mosaic-G5 family. Hoverfly and CUAV become new partners alongside 3DR, Holybro, Gateworks, Systork, MikroElektronika, ANavS, ARK Electronics, GNSS Store, ArduSimple and SparkFun. The established partners already offer boards or integration products based on the modules. According to Septentrio, the range offers developers different shapes and routes to fit the modules into UAVs, robots and further autonomous platforms.

At the same time, Septentrio releases four open-source hardware reference designs named mosaicG5-HAT, TeenG5, moTi and G5Dot. Together they connect the receivers to NVIDIA computers, Raspberry Pi, Arduino, Teensy and M.2 slots. Septentrio says ready-made starting points reduce the hardware development a team has to carry out before it can use high-precision GNSS in a new system. The company presents the open designs as a complement to the commercial boards, not a replacement for them.

Modules in the family occupy 23 mm x 16 mm and start at a mass of 2.2 g. Positioning is multi-frequency and multi-constellation, covering NavIC, QZSS, BeiDou, GLONASS, Galileo and GPS.

Septentrio’s Market Access Manager, Gustavo Lopez, argues that a technology gains value as its community and ecosystem grow. His stated aim is to supply building blocks that let partners and developers innovate on top of mosaic-G5. Pairing partner products with open designs, he adds, allows developers to create integrations that Septentrio could not build by itself.

Why it matters

Positioning hardware for small unmanned platforms is constrained by space, payload and power, and the size and weight of the mosaic-G5 modules address that constraint directly. What remains for an integrator is the carrier electronics around the receiver, and that is the area the new partners and reference designs cover.

Septentrio, whose high-precision GNSS products serve UAVs and robotics as well as construction, mining, surveying, mapping, shipping and logistics, now offers a choice between ready-made partner boards and open designs that a team can adapt.
