\*This was tested using NTRIP corrections while flying the drone and for processing the Flux scan measured blind against ground control points. Actual accuracy may varry depending on a number of factors including GNSS signal quality, base station quality, and other environmental factors.

## Operating Temperatures

Freefly Flux is designed to operating in temperatures between -20 °C to 40 °C. When operated in an ambient temperature > 40 °C, the metallic surfaces of the sensor may be hot enough to potentially cause skin burn. Avoid skin contact with the sensor’s base, lid and the heatsink when the sensor is operated under these conditions. The sensor should not be used in an ambient temperature above 40°C. The maximum safety certified ambient operating temperature is 40°C.

When the sensor reaches the maximum operating temperature specified below, the sensor may become inactive and shut off.

## Recommended Storage Conditions

Store the product in a dry, well-ventilated place. The recommended ambient temperature is 23±5°C, and the humidity between 30% and 70%.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.freeflysystems.com/ecosystem/payloads/flux-lidar/technical-specs.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
