Navigation instrument data for AI reference-frame records
NIST publishes measurement-traceability guidance.
NAICS 334511 · Search, Detection, Navigation, Guidance, Aeronautical, and Nautical System and Instrument Manufacturing
NIST publishes measurement-traceability guidance. An instrument manufacturer can define an original bench-record exercise that preserves the reference frame, observation time and configuration stated in its sources. NIST measurement context
Draw a fictional orientation marker and supply an original frame glossary. Create sample observations with explicit units and view directions. Ask the assistant which record answers a stated reference-frame request. Include a rotated diagram, an observation from a different unit and a later configuration change. The key should follow the supplied glossary and preserve the observation's original context.
Annotate instrument, reference frame, orientation, unit, observation time and configuration. Hold out a new marker arrangement for evaluation. Score frame confusion, wrong-unit joins and a later configuration applied to earlier evidence independently. Any conversion should use a rule and inputs supplied in the exercise.
Use inert props and invented records with no operational route, location or guidance instructions. Customer navigation data, licensed designs, proprietary software and outside calibration reports need appropriate authority and qualified review. Describe the context-review task and checked examples in the licensing brief. Confirm buyer scope before preparing commercial material.

Original Fiund exercise
A heading is only meaningful in its named frame
An original orientation diagram uses two invented frame references and no real navigational data.
| Record | Source | What it records |
|---|---|---|
| 1 | Frame glossary | Reference B is rotated +30° from A; positive angles increase clockwise in this sketch. |
| 2 | Reading | Marker direction +20° from B. |
| 3 | Request | Express the same direction relative to A. |
Question for the model
What angle represents that direction in A?
Show the reference answer and checks
The direction is +50° from A: move +30° to B, then +20° from B to the marker. Records 1 and 2 define both rotations in the same clockwise convention. Keep the raw +20° with its B label for traceability.
- Treating the local reading as an A reading
- Using the opposite sign for the documented frame rotation
Fields to preserve
- reference_frame
- Specifies angle origin
- rotation_convention
- Defines positive direction
- converted_angle
- Records the requested frame result
Test another case
Use a sum above 360° and require normalizing only after applying the frame transform.
Toy geometry only; no flight, marine, routing, actual navigation readings or operational instructions.
Discuss a contribution
Describe the sources you control, the task they could support and what has already been checked. Use the existing-data assessment for an archive or the collection brief for a new recording project. The contributor agreement defines Fiund’s licensing authority and compensation. A guide or fictional exercise does not establish an accepted collection or a sale.
