    Capacitors used in space missions require stringent reliability standards due to the extreme conditions present in space, including radiation, vacuum, temperature variations, and cosmic rays. Capacitors function as devices for storing and subsequently releasing electrical energy. They are essential for filtering noise, stabilizing voltage, and maintaining precise timing in electronic circuits. Radiation Hardness: Space environments…

    Every very small aperture terminal (VSAT) installation should be done professionally and to the highest standard, no matter where the location is. But the more remote the site, the more critical it is that the installation is reliable and professional. This is because every additional visit to a hard-to-reach site, for maintenance or troubleshooting, is…

    A satellite phone, also known as a sat phone, is a mobile communication device that allows users to establish communication links through satellites orbiting the Earth. Unlike conventional cellular phones which rely only on ground-based towers, satellite phones utilize satellites to facilitate communication over vast distances, including remote areas, oceans, deserts, and other locations where…

    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.

    Synthetic Aperture Radar (SAR) is a specific satellite that can capture imagery in all weather conditions, day or night. SAR sends a microwave radar signal to the earth’s surface to detect physical properties. Depending on the ground feature’s properties, some or all of the signal will bounce back up to the sensor creating an image…

    Tasking is the act of “ordering” new satellite imagery from a specific satellite. To task a satellite, coordinates of an area of interest (AOI), time frame and interval are sent to the satellite provider. The satellite will capture an image of that area during the specified time period, weather permitting. The “tasked” image is then…

    Medium resolution refers to the spatial resolution size of a satellite image. In simple terms, the resolution type will determine the clarity of your optical image. The smaller the pixel size, the more “clear” your image will look. Medium resolution is the second largest size per pixel offered by a satellite provider. The size of…
