Blueprint: Range-Certified Observation Station, Version 2 — Build Specification (Design Blueprint, Simulated, Not Built)

DESIGN BLUEPRINT — SIMULATED, NOT MEASURED — NOT BUILT. This blueprint is the full build specification for the design presented in the source paper 'A Range-Certified Observation Station, Version 2: Thermal Channels, Automated Tracking, Catalogue Cross-Match, and a Fused Two-Node Trajectory Budget' (DOI: 10.5281/zenodo.24109707), whose design this blueprint specifies. The station is a passive observation instrument: two nodes on a surveyed 1500 m baseline, each carrying a visible camera and 905 nm laser rangefinder channel inherited from the version 1 design (DOI: 10.5281/zenodo.24102256), a 640 x 512 thermal camera (340 microrad pixels, NETD 40 mK), a motorised tracking pedestal, a GPS-disciplined clock (10 microsecond time tags), a barometer, compute, power and communications. The blueprint gives the system architecture, a bill of materials per node and per station with the specifications each part must meet (no prices: the source design gives none), site survey and installation procedures, an assembly and integration sequence, calibration and commissioning procedures (bore-sighting, rangefinder verification against surveyed targets, clock discipline checks, a 0.20 K thermal contrast criterion, and fused-stamp verification), the operating envelope (Class A and Class B stamps day and night, lag-limited tracking at 0.496 rad/s, cue-to-lock times of 1.6 s typical and 4.1 s worst case, trajectory prediction limits), the satellite TLE and ADS-B cross-match procedure with its fixed 'consistent with' stamp language and the residual classes that produce no match, failure modes and degradation behaviour, a maintenance schedule, and an explicit statement of what the blueprint does not claim. In the source worked example the fused station certifies worst-axis position to 0.0089 m, size to 0.00703 m, velocity to 0.0085 m/s and acceleration to 0.0119 m/s squared, all SIMULATED, NOT MEASURED.
