    For satellite data, latency refers to the time between satellite observation and the time data is available to users. Earth science data providers use different terminology to describe data latency. Near-real-time (NRT), low latency, and expedited are often used interchangeably to refer to data made available more quickly than routine processing allows.

    Connecting to a Ground Station A ground station is a physical location with an antenna that allows a satellite operator to downlink the imagery from their satellite after it’s been collected. When launching, most companies don’t build their own ground stations. Instead, they look for partners who already have large networks of ground stations. These…

    Trick question: it depends on what you are trying to do. What does resolution mean? The resolution of Earth observation data is determined by three factors: spatial resolution, spectral resolution, and temporal resolution. While all three have to be considered when looking at satellite data, most people mean “spatial resolution” when they ask about resolution.…

    Soil moisture estimates can help farmers assess plant health, aid in predicting crop yields, let governments can help alleviate and protect against floodings, measure urban water use for city planners, and more. While ground sensors are the most accurate tools for tracking water, they are costly and difficult to move quickly. Using satellite sources provides…

    Real-time satellite data is a trendy concept and a question that our customers sometimes ask. But real-time satellite data is not what you think it is. As with most high-quality feeds, limitations on data refresh come from transfer speeds and processing speeds. In best-case scenarios, it could take only a few minutes between data capture…
