NASA Station Leads Way for Improved Measurements of Earth Orientation, Shape
10 Mar 2016NASA has demonstrated the success of advanced technology for making precise measurements of Earth’s orientation and rotation – information that helps provide a foundation for navigation of all space missions and for geophysical studies of our planet. The technology includes a new class of radio antenna and electronics that provide broadband capabilities for Very Long Baseline Interferometry, or VLBI. This technique is used to make precise measurements of Earth in space and time.
NASA Contributes to Global Standard for Navigation, Studies of Earth
25 Feb 2016The surface of Earth is constantly being reshaped by earthquakes, volcanic eruptions, landslides, floods, changes in sea levels and ice sheets, and other processes. Since some of these changes amount to only millimeters per year, scientists must make very precise measurements of the landscape and ocean in space and time in order to study their evolution and help mitigate their impacts.
RINEX V3 GNSS Data at CDDIS
06 Jan 2016Starting with data from 2016, all RINEX V3 data using the RINEX V3 filenaming convention will now be made available in the operational GNSS data archives at the CDDIS. This change has been implemented at the IGS data centers in accordance with the IGS RINEX 3 transition plan (http://bit.ly/1Md7VhU).
