 This article is a comprehensive walk-through showing how to use the [Azure Orbital Ground Station (AOGS)](https://azure.microsoft.com/services/orbital/) to capture and process satellite imagery. It introduces the AOGS and its core concepts and shows how to schedule contacts. The article also steps through an example in which we collect and process NASA Aqua satellite data in an Azure virtual machine (VM) using NASA-provided tools.
 
-Aqua is a polar-orbiting spacecraft launched by NASA in 2002. Data from all science instruments aboard Aqua is downlinked to the Earth using direct broadcast over the X-band in near real-time. More information about Aqua can be found on the [Aqua Project Science](https://aqua.nasa.gov/) website. With AOGS, we can capture the Aqua broadcast when the satellite is within line of sight of a ground station.

-A *contact* is time reserved at an orbital ground station to communicate with a satellite. During the contact, the ground station orients its antenna towards Aqua and captures the direct broadcast data. The captured data is sent to an Azure VM as a data stream that is processed using the [RT-STPS](http://directreadout.sci.gsfc.nasa.gov/index.cfm?section=technology&page=NISGS&subpage=NISFES&sub2page=RT-STPS&sub3Page=overview) (Real-Time Software Telemetry Processing System) provided by [Direct Readout Laboratory](http://directreadout.sci.gsfc.nasa.gov/) at NASA to generate the Level-0 Production Data Set (PDS) product. Further processing of the Level-0 product is done using IPOPP (International Planetary Observation Processing Package) tool, also provided by DRL to produce higher level products.
