Mission architecture
The [https://web.archive.org/web/20060524143309/http://web.ew.usna.edu/~midstar/images/main/architecture.jpg baseline MidSTAR mission] includes a single spacecraft under the command and control of a single satellite ground (SGS) station located at USNA, Annapolis MD. (Lat. 38.98 N, 76.49 W). The ground station forwards downlinked data files to the Principal Investigators via the Internet. Secondary ground control will be available on an as-needed/space-available basis through Naval Postgraduate School (NPS), Monterey CA (36.6 N, 121.89 W). Launch segment for MidSTAR is either the Delta IV or Atlas V EELV. The orbit is tailored to payload requirements; where no requirements exist, the orbit of the primary payload or one of the other secondary payloads is accepted. In order for the spacecraft to be seen from USNA SGS at an [https://web.archive.org/web/20060524143315/http://web.ew.usna.edu/~midstar/images/main/AzElRange.jpg elevation] greater than 30 degrees and range simultaneously less than 900 km, the must be 500 ± 200 km with inclination greater than 35 degrees.{{cite web|archive-url=https://web.archive.org/web/20060524143257/http://web.ew.usna.edu/~midstar/images/main/access.jpg|url=http://web.ew.usna.edu/~midstar/images/main/access.jpg|title=Midstar-1 Orbit Track|archive-date=May 24, 2006|publisher=U.S. Naval Academy}}
