mosaic-X5 GNSS module enables compact high-performance components for UAVs


Aerial drones have proven to save time and costs for jobs such as mapping, survey and inspection. Applications like photogrammetry require centimeter-level accuracy to create orthomosaics used for resource/land monitoring or construction. Hitec Commercial Solutions (Hitec) is a California based company that selected mosaic-X5 as a positioning solution for its cutting-edge components designed for the drone market.


Drones offer timely and cost-effective ways of data collection, but accurate results are paramount. Choosing the right module that is optimal for drone use is key to successful products. mosaic-X5 proved to be the ideal PPK-capable module to deliver the accuracy we needed for survey-grade results. Its small form factor and easy-to-integrate design allowed us to create a compact PCB rich with interface connectors and peripherals.

Why did Hitec choose for mosaic-X5 GNSS module?

  • mosaic-X5 offers true RTK, outperforming other professional GNSS module receivers
  • Accurate event detection and logging
  • High update rate and low latency to capture truthful accurate real-time data from fast-moving drones (delays in event logging can cause errors in positioning when drone fly at 15m/s or more)
  • Compact size and light weight for tight drone integrations and for increased battery life
  • Hitec needed a receiver properly supported by well-known autopilots and with open communication protocols for easy integration.


Hitec’s product: compact and powerful 

mosaic-X5 GNSS module was integrated into Hitec’s PositionPro GNSS board. The compact form factor of PositionPro allows it to fit into a variety of aircrafts. It is much smaller and lighter than a lot of alternatives that offer reduced performance by comparison. Hot shoe input pin and SD card allow precise event logging, ideal for photo time stamping. The board features on-board precision magnetometer and barometer. It provides USB, UART, I²C and CAN interfaces and uses open-source autopilot firmware with full support for PPK for easy Pix4D mapping workflow.
