Microsatellite Constellation Configuration: 0 minutes
Source publication
National Aeronautics and Space Administration (NASA) Deep Space Network (DSN) currently administers the navigation system for all of NASA’s Martian spacecraft landers. For its travel to Mars, the spacecraft is located and guided via 2-way radio communication and navigation system. Although beyond par navigation potential is guaranteed by DSN, such...

... orbital configuration repeats every 137 minutes. For determining accurate position for 800 seconds, approaching spacecraft will be highly dependent on the microsatellites. Since in comparison to the constellation orbital duration this duration is notably shorter, visibility of the microsatellite is assessed for a single period. Following Fig. 4 through Fig. 7 demonstrates the near equatorial view of the constellation behaviour over the span of 120 minutes. Visibility for microsatellites over 1 full period is very well represented in Fig. 4-7. The augmented microsatellite constellation ensures superior visibility along with 4 (Fig. 4, Fig. 5, Fig. 7) or more microsatellites ...

Microsatellite visibility worst-case scenario has been demonstrated in Fig. 7, in which microsatellite No. 5 comes within view-range moments before microsatellite No. 6 eclipses. Optimal spatial distribution of the microsatellites has also been demonstrated by the constellation. ...

Decay calculations play an important role in reactor physics simulations. In particular, the isotopic decay of the burned fuel during refueling is important for predicting the startup reactivity of the following burn-up cycle. In addition, there is a growing interest in high-fidelity simulations where the mesh in the burn-up region can involve mill...
