ANELLO Photonics

ANELLO Photonics is a Santa Clara, California company building solid-state, high-precision inertial navigation and sensing products for positioning, navigation and orientation when GNSS is jammed, spoofed, blocked or otherwise unavailable. Its products are powered by SiPhOG (Silicon Photonics Optical Gyroscope), a chip-scale optical gyroscope built on standard semiconductor processes. The developer surface is an embedded one rather than a web API: ANELLO Ground INS, Ground IMU, Maritime INS, Aerial INS, X3 IMU and the Evaluation Kit expose a documented ASCII and RTCM-binary message protocol over RS-232 serial, USB-C and UDP/Ethernet, with a public developer manual, a first-party Python configuration and logging tool, a ROS/ROS2 driver that publishes machine-readable .msg/.srv interface definitions, and PX4/ArduPilot and MAVLink integrations.

ANELLO Photonics publishes 1 API on the APIs.io network. Tagged areas include Company, Inertial Navigation, Optical Gyroscope, Silicon Photonics, and GNSS.

ANELLO Photonics’ developer surface includes documentation, API reference, getting-started guide, engineering blog, support, CLI, changelog, and 15 more developer resources.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/anello-photonics: open an issue to ask a question, or submit a pull request to add artifacts.
