INSIDE THE CONCEPT

Reception. Processing. Connection.

01 / GNSS

u-blox F10 platform

Dual-frequency GNSS reception is the design basis. The exact receiver must support the raw observations required by the proposed onboard RTK implementation.

02 / COMPUTE

STM32H753

Planned onboard RTK processing, alongside an IIS2MDC magnetometer. Positioning accuracy and convergence require complete-system testing.

03 / NETWORK

4G CAT.1

Network correction access is planned at the module. Coverage, SIM arrangements, service regions and subscriptions must be confirmed for each deployment.

CONNECTIONS & DESIGN

Know every connection.

Made for a deliberate installation.

The current enclosure concept separates antenna connections, flight-controller wiring and maintenance access.

Integration checklist ↗
Flight-controller serial
6-pin UART2 concept: 5V, RX2, TX2, PPS, EVENTA, GND. Final pin positions pending.
CAN bus
4-pin connector; DroneCAN support planned and subject to firmware validation.
Antenna connections
Separate GNSS and 4G SMA connections on opposite sides.
Maintenance
Side-mounted USB-C and TF card slot; debug logging planned.
Status indication
Separate RTK, 3D positioning and 4G indicator concepts.
Enclosure & dimensions
Black CNC enclosure concept. Final dimensions and weight pending.

Do not connect using a generic GPS/I²C harness. The proposed UART2 signal set requires a dedicated, verified cable. This page is not a pinout or wiring instruction.
