Where it fits

Start with the system context.

Dynamic airborne measurement module. Confirm the target, environment, update behavior, interface, mounting, and validation plan before design-in.

  • UAV altitude holding
  • Terrain following
  • Mapping and surveying
  • Dynamic airborne platforms

Measurement and integration

Choose the behavior your application can validate.

Review measurement behavior and interfaces together with the target, environment, host system, and validation plan. Not every mode or interface is the right fit for every application.

Measurement modes

  • Single Measurement
  • Continuous Measurement
  • Fast Measurement · 10 Hz
  • Multi-Sample / Confidence Mode (Brute Mode)

Interfaces and workflow

  • UART / TTL
  • ArduPilot evaluation
  • Pixhawk evaluation
  • Lua integration workflow

Mechanical and application reference

Use the right visual for the decision.

A large 2D diagram or CAD view is reserved for mounting and integration decisions. An approved integration reference appears separately when one is available.

Specification references

Keep the conditions with the number.

Use these values for initial comparison, then confirm the applicable conditions against the current technical document before design-in.

Range class 3 km class Target, ambient light, distance, and configuration dependent.
Fast Measurement 10 Hz Shorter effective range; do not treat 1 km as a universal maximum.
Brute Mode Three most consistent readings Displays distance and a confidence value; confidence is not a percentage.

*Target reference: White target · approximately 95% reflectivity

Integration resources

Prepare the next engineering conversation.

Use the published documents to review electrical, mechanical, communication, and calibration requirements. Additional files are released only after revision and interface checks.
