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.

GNSS positioning is strongly challenged in urban canyon areas. The signal reflection induces multipath and non-light-of-sight (NLOS). These signal blockages and reflections are caused by the obstacles of signal transmission between the satellites and receiver.

Europe has set out to abolish the national patchwork for drone operations. Faced with different drone rules all over the continent, the legislative bodies of the European Union have been very busy lately.
The second satellite to join the constellation that forms the European Data Relay System (EDRS) was launched by Arianespace on August 6, at 21:30 CEST (19:30 UTC). The satellite was launched on board an Ariane 5, together with a second passenger, Intelsat 39, from Europe’s Spaceport in Kourou, French Guiana.

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.

Airbus has been selected by the European Space Agency (ESA) to build the European component of the SMILE satellite (Solar wind Magnetosphere Ionosphere Link Explorer). SMILE will be the first joint satellite mission between ESA and the Chinese Academy of Sciences (CAS), following on from the success of the Double Star / Tan Ce mission which flew between 2003 and 2008.
