Critics argue that GNSS could lead to an invasion of people’s privacy. Weather prediction (GNSS radio occultation) – Measurement of atmospheric bending of GNSS satellite signals by specialized GNSS receivers in orbital satellites can be used to determine atmospheric conditions such as air density, temperature, moisture and electron density.
Constellation Observing System for Meteorology, Ionosphere, and Climate (COSMIC) is a program designed to provide advances in meteorology, ionospheric research, climatology, and space weather by using GPS satellites in conjunction with low Earth orbiting (LEO) satellites.
Their main uses are in the fields of atmospheric data for weather prediction, ionosphere, gravity and climate research, as well as disaster prevention. Like the Yunhai-2 series, the satellites reportedly use the Global Navigation Satellite System Radio Occultation ( GNSS-RO ).
Weather reconnaissance aircraft, such as this WP-3D Orion, provide data that is then used in numerical weather forecasts.. The atmosphere is a fluid.As such, the idea of numerical weather prediction is to sample the state of the fluid at a given time and use the equations of fluid dynamics and thermodynamics to estimate the state of the fluid at some time in the future.
Accurately predicting the weather is hard — really hard, but a new AI-powered forecast model just hit a milestone that has experts saying your forecast could soon get more accurate, and further ...
Yunhai-2 is a Chinese meteorological satellite constellation developed by the Chinese military. [1] The satellites reportedly use the Global Navigation Satellite System Radio Occultation to collect atmospheric data for weather prediction and for ionosphere, climate and gravity research. [2]
It is also expected that one of the sentinel satellites will test a new experiment with regards to weather prediction. As a part of its payload, it will use Global Navigation Satellite System Radio Occultation (GNSS-RO), a method to detail changes and information of different layers in the atmosphere. [18]
It features a filtering system for the catalog to only display objects with matching name or ID. The pass predictions generates, among other things, the time window, minimum elevation and the apparent brightness of the object in the sky. Satellite Tracking provides detailed real-time and pass predictions for Earth orbiting satellites.
