Some good news has been reported and some nice progress has been made by the Indian Space Research Organization (ISRO) this year.
The successful launch of the PSLV-C41 rocket carrying India’s eighth navigation satellite IRNSS-1I from Sriharikota put smiles back on the faces of scientists of the ISRO in April amid tough times as the space agency was struggling to restore the snapped link with its recently launched communication satellite Gsat-6A.

How can I walk my dog on the Moon? What happens if I sneeze in space? Just some of the questions that more than 500,000 children around the world will be asking and attempting to answer over the next months, as part of this year’s FIRST LEGO League competition, a global STEM program with an annual theme that inspires and challenges young engineers and scientists.

Nominations for ION Fellows and Annual Awards are being accepted through October 15. The ION Annual Award Program is sponsored by The Institute of Navigation (ION) and recognizes individuals making significant contributions or demonstrating outstanding performance relating to the art and science of positioning, navigation and timing.

According to the European Commission “…GNSS cannot be the sole means of PNT information … for critical applications requiring continuous availability and fail-safe operations.”
Similar realizations in the United States, United, Kingdom, South Korea and elsewhere have led to a revitalization of efforts to examine Alternative Positioning, Navigation and Timing (APNT) systems that could complement and reinforce our exceptionally valuable, yet vulnerable, GNSS signals.

At the ESA/JRC International Summer School on GNSS in Austria last month, one of the participants asked us during the evening panel — where they can address any kind of question to the lecturers and experts — What does satellite navigation look like in 50 and in 100 years from now?

This article presents the authors’ experience in setting up an airborne pseudolite (UAVlite) with the needed ground-based infrastructure to perform code and phase ranging performance analysis. UAVlites transmit GNSS-like signals free from any local transmitter multipath (in contrast to ground-based transmitters) and can in principle be localized in real-time through a synchronized network of ground stations which may also broadcast the UAVlite positions in real-time.

One of the great engineering successes of the International Civil Aviation Organization (ICAO) and its expert panels is the standardization of globally harmonized Communication, Navigation and Surveillance (CNS) systems. These standards, sometimes supported by more detailed industry standards, provide safe and interoperable services between aircraft and the ground and space systems supporting them.
