A 3D-printed plastic mount that fixes the LightWare SF30/D laser altimeter to a DJI M300 RTK or M350 RTK drone for SkyHub True Terrain Following. HobiTech supplies it in India as an authorised SPH Engineering partner.
Technical
| Material | 3D-printed plastic |
| For altimeter | LightWare SF30/D laser altimeter |
| For drone | DJI M300 RTK, DJI M350 RTK |
| SF30/D max range (SkyHub user manual) | 200 m |
What is the laser altimeter mount used for?
True Terrain Following (TTF) keeps a drone at a steady height above the ground or water, using live readings from an altimeter on the drone. SPH Engineering states SkyHub TTF works as low as 0.5 m above ground. It matters for low-flying survey sensors such as ground penetrating radar and magnetometers, where the distance between sensor and surface must stay constant.
The LightWare SF30/D is the laser altimeter supported by SkyHub. The SkyHub user manual lists a 200 m maximum range and a UART interface, powered from SkyHub. A SkyHub 3 cable for the SF30/D is also sold separately. This mount holds the SF30/D on the airframe of a DJI M300 RTK or M350 RTK.
SPH Engineering states the laser altimeter can be used in any country, but is less reliable in some conditions and over reflective surfaces such as water, ice, snow and sand under bright sun. The manual strongly recommends a target altitude of no more than 10 m for the laser altimeter over water.
HobiTech's SF30/D kit already includes plastic mountings for the DJI M350/M300 RTK. Buy this mount separately when you need a spare, a replacement, or a mount for a second drone.
Which altimeter mount do I need?
| Your altimeter | Type | Max range (SkyHub user manual) | Mount to order | Mount build |
|---|---|---|---|---|
| Nanoradar NRA24 | 24 GHz radar | 50 m | NRA24 mount for M300/M350 RTK | 3D-printed plastic |
| Ainstein US-D1 | 24 GHz radar | 50 m (0.5 m minimum) | US-D1 mount for M300/M350 RTK | 3D-printed plastic |
| LightWare SF30/D | Laser | 200 m | Laser altimeter mount for M300/M350 RTK | 3D-printed plastic |
All three mounts are made for the DJI M300 RTK and M350 RTK. Each one fits only the altimeter named on it, so match the mount to the altimeter you fly.
What else do you need for True Terrain Following?
- SkyHub on-board computer: SPH Engineering ships it with mountings and cables for the DJI M300/M350 RTK by default.
- SkyHub True Terrain Following package: the software that holds height from live altimeter readings.
- An altimeter: the Ainstein US-D1 radar, the Nanoradar NRA24 radar or the LightWare SF30/D laser. The SkyHub user manual lists all three with a UART interface, powered from SkyHub.
- A mount for that altimeter, such as this one.
- UgCS: the SkyHub user manual asks for UgCS 5.3.0 or higher, for example UgCS EXPERT.
A protective box for SkyHub and the TTF kit is available for transport. See the full range in Integrated Systems.

Why buy the laser altimeter mount 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. SPH training is available too, including the UgCS Area Scan and True Terrain Following course.
Frequently Asked Questions
What does the laser altimeter mount hold?
It fixes the LightWare SF30/D laser altimeter to a DJI M300 RTK or M350 RTK drone.
Is a mount already included with the SF30/D kit?
Yes. The SF30/D kit includes plastic mountings for the DJI M350/M300 RTK. This mount is sold separately for spares or extra drones.
Can I fly the laser altimeter over water?
With care. The SkyHub user manual strongly recommends a target altitude of no more than 10 m for the laser altimeter over water.
Why choose laser instead of radar?
SPH Engineering states the laser altimeter can be used in any country, while use of a 24 GHz radar altimeter must be checked locally.
Will this mount fit a radar altimeter?
No. The NRA24 and US-D1 radars each have their own mount. See the table above.
