The second Lockheed Martin-built GPS III space vehicle (GPS III SV02)—also known as Magellan—was recently encapsulated within its protective fairings in preparation for Thursday’s scheduled launch. GPS III will launch tomorrow from Space Launch Complex-37 (SLC-37) at Cape Canaveral Air Force Station, Florida.

The Air Force’s Space and Missile Systems Center recently awarded Maxar Technologies a firm fixed-price delivery order under the Hosted Payload Solutions Indefinite Delivery/Indefinite Quantity contract. The National Aeronautics and Space Administration will fund the contract, which will commercially host NASA’s Tropospheric Emissions: Monitoring of Pollution, or TEMPO instrument.

Today’s vehicular navigation systems couple global navigation satellite system (GNSS) receivers with an inertial navigation system (INS). Low Earth orbit (LEO) satellite signals are a particularly attractive INS aiding source in GNSS-challenged environments.

Spectrum regulators have denied a request for an extension to file comments on a petition to rewrite the rules governing Ultra-Wide Band (UWB), a wireless technology that spreads the content of a signal across hundreds of megahertz of frequencies and poses a potential interference risk to GPS.

Spectrum regulators are considering a request to modify tough restrictions on devices and systems relying on Ultra-Wideband (UWB) technology, an approach to using frequencies that skips across wide swaths of spectrum instead of confining its signals to distinct, narrower bands.

Ligado Networks is pushing spectrum regulators to make a decision on its request to allow satellite frequencies near the GPS band to also be used for terrestrial 5G networks.

Trimble recently introduced the latest version of its core real-time monitoring software—Trimble 4D Control software. Version 5.0 provides new features that enable users to streamline real-time structural monitoring system deployment as well as simplify the connection to geotechnical sensors. Trimble 4D Control software enables project stakeholders to monitor critical infrastructure such as dams and bridges along with mines and buildings surrounding construction sites and tunnels.

Safety and cost reasons led U.S. aviation regulators to choose a somewhat less efficient system for oceanic air traffic control, government watchdogs told Congress, adding that the majority of the airlines the researchers surveyed agreed with that approach.
