Freefly LR1 Laser Range Finder Upgrade
The Freefly LR1 Laser Range Finder Upgrade is an add-on distance sensor module for the LR1 payload on the Freefly Astro. Built around an integrated Lightware SF20/C laser sensor, it measures target distance up to 100 m and displays a live distance readout in Auterion Mission Control (AMC). When you capture a photo, the distance at that moment is written into the image metadata, adding a measured range to every shot for mapping and inspection work. The module is user-installable, mounts to the LR1 payload with four screws, and ships with its matched counterweight.
Add-on laser distance sensor for the Astro LR1 payload. Live range readout in AMC and distance saved to image metadata, up to 100 m.
Features
- Integrated Lightware SF20/C laser range finder measuring up to 100 m at 70% reflectivity
- Live distance readout displayed in Auterion Mission Control (AMC) at a 5 Hz update rate
- Distance at the moment of capture is written into the image metadata, tying a measured range to each photo
- User-installable: mounts to the LR1 payload with four screws and plugs into the expansion port
- Includes the specific counterweight required to keep the LR1 payload balanced with the module fitted
- Lightweight at just 45 g installed
- Can be run alongside the LR1 Thermal Upgrade using the larger counterweight plate included with the Thermal Upgrade

Compatibility
- Any Freefly Astro equipped with the LR1 Payload
- Can be used together with the LR1 Thermal Upgrade (910-00840) when using the larger counterweight plate included with the Thermal Upgrade
- Requires an additional app to be installed on the Astro to use the distance sensor
What's included
- 1 × Distance Sensor Module for LR1
- 1 × Sensor module counterweight
- Sensor mounting screws (2 × M3 × 5 BHCS, 2 × M3 × 10 SHCS)
- Counterweight mounting screws (3 × M3 × 8 FHCS)
Installation and notes
- The module is user-installable. Mount it to the LR1 payload with the included screws, install the matched counterweight, and plug the module into the expansion port.
- Using the distance sensor requires installing an additional app on the Astro. Follow Freefly's installation and setup instructions for the LR1 Laser Range Finder module.
- Auxiliary modules on the LR1 payload require the correct counterweight to keep the payload balanced. The needed counterweight is included; if you also run the LR1 Thermal Upgrade, use the larger counterweight plate that ships with the Thermal Upgrade.
FAQ
What does this upgrade add to the LR1 payload?
It adds a laser range finder that measures distance to a target, shows a live readout in Auterion Mission Control, and records the distance into the metadata of each captured image. That gives every photo a measured range, which is useful for mapping and inspection workflows.
What is the maximum range?
Up to 100 meters at 70% reflectivity, using the integrated Lightware SF20/C sensor, with a 5 Hz update rate in AMC. Real-world range depends on the target's reflectivity and conditions.
What do I need to use it?
A Freefly Astro with the LR1 Payload installed. The distance sensor also requires an additional app to be installed on the Astro. Everything needed to mount the module (screws and the matched counterweight) is included.
Can I install it myself?
Yes. It is user-installable. It mounts to the LR1 payload with four screws and plugs into the expansion port. Follow Freefly's setup instructions, and install the included counterweight so the payload stays balanced.
Can I use it at the same time as the LR1 Thermal Upgrade?
Yes. The Laser Range Finder Upgrade and the LR1 Thermal Upgrade can be run together on the LR1 payload. When both are installed, use the larger counterweight plate that comes with the Thermal Upgrade.
Why does it come with a counterweight?
Adding an auxiliary module changes the balance of the LR1 payload. The included counterweight restores balance so the gimbal performs correctly. Install it as part of the setup.
