We chose Sk-67 108 (B0 Ia) and Sk-69 276 (O9-B0Ia) as the comparison stars on the basis of the morphology of their UV spectra compared to OB 10-64. These two stars have essentially little or no interna ...

Stellar-Aided Inertial Navigation Systems for Lunar and Mars
... An unaided INS requires a precise initial alignment and position fix. Any errors in the initialization will grow over time. Even with perfect alignment, the position and velocity information will degrade as a result of unmodelled accelerations and instrument errors. With external measurements, error ...
