SkyHub is SPH Engineering's drone onboard computer that logs geotagged data from sensors such as GPR, altimeters, magnetometers, echo sounders and methane detectors. It is for survey and geophysics teams, and HobiTech supplies it in India.

| Packaging | 21 × 29 × 11cm, 1.0kg in a cardboard box |
| Default mounting | DJI M300/M350 RTK (other drones on request) |
Documentation & data sets
What is SkyHub used for?
SkyHub sits between the drone's flight controller and the payload. It powers the sensor, reads its data, and records every reading with the drone's position and time, so the survey data is geo-referenced from the start. SPH Engineering describes it as an onboard computer that extends commercial drones for industrial sensing and automation.
All mission data is recorded offline on the drone in standard formats, including CSV, SEG-Y and NMEA-0183. No cloud or internet connection is needed. SkyHub also runs True Terrain Following, which uses an altimeter to hold the drone at a constant, low height over the ground, as low as 0.5 m according to SPH Engineering.
SPH lists these sensor types for SkyHub: ground penetrating radar, magnetometers, echo sounders, methane detectors, metal detectors, gamma-ray spectrometers and side-scan sonar. Each sensor type needs its own SkyHub software package.

Which drones does SkyHub work with?
- DJI Enterprise: M400, M350 RTK and M300 RTK, through the DJI PSDK connector.
- Cube / Pixhawk drones: SPH lists the InspiredFlight IF1200A and IF800, Wispr Ranger Pro, Harris Aerial H6, Skyfront Perimeter 8, DroneBase X4-1000, Hexadrone Tundra, Avartek Boxer and other PX4/ArduCopter drones.
By default, SPH ships SkyHub with mountings and cables for the DJI M300/M350 RTK. For the M400, add the SkyHub 3 smart cable assembly for DJI M400. The SkyHub 3 cable for DJI M300/M350 RTK is also sold separately. Mounts and cables for other drones are available on request.
What do you need to run SkyHub?
SPH Engineering notes that SkyHub should not be ordered on its own. It is only useful with a sensor kit and a software package. A typical system has:
- The SkyHub hardware (this product).
- A sensor, for example from our ground penetrating radar, bathymetry or methane detection ranges.
- The matching software package: GPR, echo sounder, methane detector or True Terrain Following.
- For terrain following, an altimeter such as the Ainstein US-D1 radar altimeter or the LightWare SF30/D laser altimeter.
- A UgCS licence, such as UgCS EXPERT, to plan and fly the mission.
A protective box for SkyHub and the TTF kit is available for transport.
Why buy SkyHub from HobiTech?
HobiTech is an authorised SPH Engineering partner based in Bengaluru, India. Every order comes with a GST invoice, and our local team supports the sensor, the drone and the software together. We also offer SPH training courses, including UgCS and True Terrain Following training.
Frequently Asked Questions
What does SkyHub do on a survey drone?
It powers the sensor, logs its data with position and time, and records everything offline on board. It also runs True Terrain Following with an altimeter.
Can I buy SkyHub on its own?
SPH Engineering advises against it. SkyHub is only useful with a sensor and the matching software package, so it is normally quoted as part of a complete system.
Which DJI drones is SkyHub compatible with?
The DJI M400, M350 RTK and M300 RTK. It ships with M300/M350 RTK mountings and cables by default; for the M400, SPH offers a separate SkyHub 3 smart cable assembly.
What voltage does SkyHub need?
It takes 12–60 V from the drone's main battery and can supply 9, 12, 15 or 18 V to the sensor, up to 5 A.
Does SkyHub need an internet connection?
No. All mission data is recorded offline in standard formats such as CSV, SEG-Y and NMEA-0183.
