The Earth observing mission that these satellites are performing requires the Earth to be in sunlight in order for data collection to occur.The other satellite is in a circular orbit with an altitude of 1400 km and an inclination of 70 degrees (TestSat).
One of the university satellites is in a sun synchronous orbit (SunSync).The shuttle is flying in a low earth orbit with a 51.6 degree inclination.The Earth observing payload is attached to three different satellites (Shuttle, SunSync, and TestSat).You have some information that may be helpful. How will you determine the extent and quality of coverage provided by the three satellites that you are assessing? Break It Down Manually calculating point-to-point access to an object positioned at every point on the Earth individually would be time consuming. Additionally, you would like to know if any areas of the Earth will be covered by two or even three sensors simultaneously, during daylight hours, and if so, for how long. You need to know when any or all of the three satellites can “see” the portion of the Earth’s surface that falls between 60 degree and -60 degrees latitude. Because the three Earth observing payloads were all piggy-backed to space as secondary missions of other launches, they ended up in three different orbits. Their satellites launched previously on two separate space launches. The space shuttle has just lifted off with your payload on-board! The other two universities built small satellites carrying this new payload (SunSync and TestSat). Your payload was designed to be an on-orbit space shuttle experiment rather than a stand-alone satellite. This lesson covers the following STK Capabilities:Īs a university student, your senior design team has worked in conjunction with a consortium of two other universities in designing a new space-based Earth observing payload. It is acceptable to have different results. The results of the tutorial may vary depending on the user settings and data enabled (online operations, terrain server, dynamic Earth data, etc.). You can obtain the necessary licenses for this training by contacting AGI Support at or 1-80. STK Pro, STK Premium (Air), STK Premium (Space), or STK Enterprise
