CAMS [3] networks around the world use an array of low-light video surveillance cameras to collect astrometric tracks and brightness profiles of meteors in the night sky. Triangulation of those tracks results in the meteor's direction and speed, from which the meteors’ orbit in space is calculated and the material's parent body can be identified.
One of the first highly publicised events that EarthCam produced, labelled "Webcast of the Century", featured celebrations from around the world at the turn of the new millennium on New Year's Eve 1999 / New Year's Day 2000. 100 cameras were located across the world, taking pictures every 30 seconds, viewed using an interactive world map on ...
Images can be received in real-time by relatively unsophisticated, inexpensive receivers during the time the satellite is within radio range, which typically lasts 8 to 15 minutes. As of 2004 there were almost 5,000 APT receiving stations registered with the World Meteorological Organization (WMO). It is unclear what percent of the total user ...
True color image of the Earth from space. This image is a composite image collected over 16 days by the MODIS sensor on NASA’s Terra satellite. NASA Earth science satellite fleet as of September 2020, planned through 2023. Earth observation satellite missions developed by the ESA as of 2019.
Exposure time for each of the 10 narrowband channels (317, 325, 340, 388, 443, 552, 680, 688, 764, and 779 nm) is about 40 ms. The camera produces 2048 × 2048 pixel images, but to increase the number of downloadable images to ten per hour the resolution is averaged to 1024 × 1024 on board. The final resolution is 25 km/pixel (16 mi/pixel). [29]
EarthBrowser, an Adobe Flash/AIR-based virtual globe with real-time weather forecasts, earthquakes, volcanoes, and webcams. Google Earth, satellite and aerial photos dataset (including commercial DigitalGlobe images) with international road dataset, the first popular virtual globe along with NASA World Wind.
Tip and cue systems utilize a network of satellites equipped with complementary sensor technologies to track moving objects in real-time. The method involves detecting a target with a primary sensor, such as an infrared or photographic sensor, which then cues secondary sensors on the same or other satellites for more detailed monitoring.
Satellite watching or satellite spotting is a hobby which consists of the observation and tracking of artificial satellites that are orbiting Earth. [1] People with this hobby are variously called satellite watchers, trackers, spotters, observers, etc.
