The world’s fastest blind plate solver. Solves in milliseconds open new fields: live video, handheld AR, navigation without GNSS, solvers embedded in optics.

From a star field to a calibrated WCS.

Head-to-head with astrometry.net and ASTAP.

Plate solving at video frame rates.

A solve in milliseconds is fast enough to identify the sky in every frame of a video, not just in a still. That opens new work: coordinate grids, constellation figures and object labels that stay on the sky through pans and zooms; annotated timelapses and meteor-camera footage; live overlays on telescope, all-sky and broadcast streams.

Applications of blind calibration.

Availability is stated for each application.

• Astrophotography and astronomy

  Browser · available

  Blind solving of every frame in a session; WCS export for stacking, mosaics, photometry and astrometry; catalogue annotation; overlay comparison with DSS2, Pan-STARRS and 2MASS.

• Image verification and OSINT

  Browser · available

  Sky coordinates and orientation of night-sky photographs and video frames. Combined with horizon geometry and a claimed time or location, a consistency check on the material.

• Video, timelapse and live streams

  Desktop · in preparationmacOS · Windows · Linux

  Persistent RA/Dec grid, constellation figures and object annotation on recorded and live video, including meteor and all-sky cameras.

• Outreach, planetaria and sky shows

  Desktop · in preparationmacOS · Windows · Linux

  Live identification of the sky seen by the camera, in place of a simulated sky.

• Mobile AR

  iPhone · in preparation

  Overlay anchored to the solved star field rather than to the magnetometer and gyroscope heading, which is typically off by several degrees or more.

• Celestial navigation without GNSS

  In development

  Position from star-derived attitude and the device’s inertial sensors, for GNSS-denied or jammed environments at sea and on land. Simulations on synthetic data put the target accuracy below 1 km, about 200 m in the optimistic case; field trials are in preparation.

• Defence and security

  With partners

  A passive attitude and position reference from the star field, with no RF emission and nothing to jam or spoof: backup navigation for vessels, land vehicles and UAVs in GNSS-denied environments; boresight calibration and pointing verification for EO/IR sensors and optical turrets; time and orientation checks on recovered imagery. Requires sky visibility.

• Star trackers: satellites, balloons, UAVs

  With partners

  Lost-in-space attitude from a single frame, followed by frame-to-frame tracking, on commercial cameras and processors. For research and prototyping; not flight-qualified.

• Telescopes, binoculars and AR optics

  With partners

  Embedded pointing determination for finders, smart telescopes and AR binoculars.
