Global Navigation Satellite Systems Engineering, Policy, and Design
A new cloud-based, digital reality visualization platform in the Hexagon AB booth captured the attention of CES 2020 visitors in Las Vegas this week. HxDR creates accurate digital representations of the real world through the seamless combination of reality-capture data from airborne, ground and mobile sensors.

A version of the NeQuick G ionospheric model algorithm to help single-frequency receivers to estimate and correct for the ionospheric propagation delay is now available for download from the Galileo Service Center (GSC) website). Using a new coding approach, this version is the result of intensive effort by engineers at the EU’s Joint Research Centre.

Harris Corporation has delivered an environmental monitoring sensor for the Greenhouse Gases Observing Satellite-2 (GOSAT-2), which will significantly enhance Japan’s ability to monitor greenhouse gases from space.
The Harris-built TANSO-FTS-2 (Thermal and Near Infrared Sensor for Carbon Observation-Fourier Transform Spectrometer-2) will measure greenhouse gases in the atmosphere. The newly built instrument will collect high-spectral resolution data of the Earth in five bands, which enables measurement during daylight and darkness. The instrument’s unique intelligent pointing system identifies, in real time, cloud-free areas of the atmosphere – greatly increasing the amount of useable data, according to the company.

GPS III SV01 now awaits a call up to begin pre-launch preparations. Photo: Lockheed Martin.Ushering in a new era of advanced Global Positioning System technology, the U.S. Air Force this week declared the first Lockheed Martin-built GPS III satellite “Available for Launch.”
The Air Force’s “AFL” declaration is the final acceptance of Lockheed Martin’s first GPS III Space Vehicle (GPS III SV01) prior to its expected 2018 launch. GPS III SV01 will bring new capabilities to U.S. and allied military forces, and a new civil signal that will improve future connectivity worldwide for commercial and civilian users.

Navigating the globe was once done using the sun, moon and stars as references, but modern times bring modern methods, and the majority of the world now relies on GPS — or another GNSS — for its navigation needs.
But what happens when GPS isn’t available?
A collection of Department of Defense (DoD) units and U.S. universities recently found out when they gathered at Edwards Air Force Base to evaluate various aerial platforms in a degraded GPS environment.
