Blueprint: Observation Station, Version 2 — Two-Node Thermal, Tracking and Cross-Match Station: Build, Siting, Software, Calibration and Cost Specification

SIMULATED, NOT MEASURED — NOT BUILT. A manufacturable blueprint package for the Observation Station v2 design (source DOI: 10.5281/zenodo.24109707, building on v1 DOI: 10.5281/zenodo.24102256): two nodes on a surveyed 1500 m baseline, each with a 3840x2160 visible camera and 100 mm lens (34.5 microrad pixel scale, 6.07 microrad bearing), a 640x512 long-wave infrared thermal camera (340 microrad, NETD 40 mK), a 905 nm Class 1 laser rangefinder (5-3000 m, 0.50 m), a servo pan-tilt pedestal (60 deg/s slew, Kv 30 per s, lag-limited tracking at 0.496 rad/s), a GPS-disciplined clock (10 microsecond tags), barometer, edge compute, ADS-B receiver, communications, power and enclosure. The blueprint gives a full bill of materials per node and for the pair with specifications matching the source budgets, a costed build estimate computed by the deposited script (complete station US$48,700 to US$118,500, midpoint US$83,600, market-typical ranges for the component classes, no model numbers asserted), siting and survey procedure for the 1500 m baseline (0.01 m, 6.67 ppm), node construction, thermal/visible boresighting, a software pipeline specification implementing rate-aided cueing (stale-bearing cueing caps at 0.068 rad/s typical and 0.026 rad/s worst case, printed), TLE and ADS-B cross-match with the source windows and the fixed 'consistent with' stamp language (never identification), calibration and acceptance tests with pass/fail numbers from the source budgets including the night-stamp degradation (0.121 m worst-axis at 1000 m against 0.0089 m daylight) and the 4.5 percent satellite chance-coincidence figure at 550 km with a one-day-old element set printed honestly, the operating envelope, failure modes and a maintenance schedule. 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.
