GNSS Foresight Heralds New Direction for Aviation, UAVs, Air Taxis and Entire PNT Industry

Spirent Communications has launched GNSS Foresight, a cloud-based solution that empowers GNSS users with advance knowledge about the strength and reliability of GNSS signals in exact locations within their operational areas. The service will have early application for aviation, unmanned and autonomous platforms, but Spirent VP Jeremy Bennington told Inside GNSS that its potential is far wider.

New Multipath Rejection Method: Multicorrelator Receiver with Extended Kalman Filter

A new method for multipath rejection employs a multicorrelator-based GNSS receiver with an extended Kalman Filter (EKF) as an iterative solver, replacing the conventional delay locked loop (DLL) code tracking. The technique significantly reduces the positioning error and has low complexity. It can therefore be implemented in a real-time processing environment.

Washington View: Big Wheels Keep On Turning – Rolling On The River To 5G

Ligado Networks had an early-year win in the form of a Federal Communications Commission denial of the National Telecommunications and Information Administration Stay Petition involving Ligado’s license for a terrestrial service in the mobile satellite services L-band. The company continues to roll toward deployment of a nationwide 5G network. While filings trickle in from the private sector, the feds work quietly behind the scenes on Congressional due-outs. In short, wheels big and small keep churning down the river to 5G.

Italy and Qascom to Land First GNSS Receiver on the Moon

A 2023 lander in the moon’s Mare Crisium will carry the first GNSS receiver to that planet’s surface: the Navigation Early Investigation on Lunar surface (NEIL) receiver with software-defined radio (SDR) technology. The receiver will spring from agreements between the U.S. National Aeronautics and Space Administration (NASA), the Italian Space Agency (ASI) and the Italian firm Qascom srl.

Are Elliptical Galileo Satellites Usable for RTK?

Galileo satellites 5 and 6 (E18, E14) were declared unusable in February 2021 after reports indicating repeatable daily problems with RTK. This article explores the possible impact of deviant elliptical orbits on the performance of RTK and finds that there is no reason to expect any anomalies caused by high orbit eccentricity per se. Thus there is no reason to declare the satellites unhealthy.

Real-Time Automated Aerial Refueling with Stereo Vision: Overcoming GNSS-Denied Environments In or Near Combat Areas

In-flight refueling requires sustained minimal separation between paired aircraft with little room for error. In or near combat zones, wide-area GPS-denial or spoofing means that an GPS-independent system must be available. Regardless of the selected sensor package, a common set of properties must be satisfied to facilitate mid-air docking: a high degree of accuracy, precision, and integrity.
