"3GPP Release-18 Physical Layer Enhancements for IoT-NTN".
"The advent of mega satellite constellations has paved the way for bringing cellular connectivity to mobile broadband as well as Internet of Things (IoT) devices in unconnected or remote regions via satellites, thus complementing the terrestrial cellular coverage. With this motivation, the 3rd Generation Partnership Project (3GPP) introduced Non-Terrestrial Networks (NTN) support for IoT technologies including Long-Term Evolution (LTE) for Machine-Type Communications (LTE-MTC) and Narrowband Internet of Things (NB-IoT) in Release-17, which are collectively known as IoT-NTN. Release-17 IoT-NTN focused on only the essential changes to the existing IoT specification to enable IoT operation in satellite scenarios."
So in case you didn't follow the techspeak, what this is about is being able to have electronic devices in the most remote parts of the world, and as long as they have electric power, they can get on the internet and transmit data and receive data by communicating through satellites. They need particular electronic circuits that speak what have become known as "internet of things" (IoT) protocols -- protocols originally designed to carry internet protocol (TCP/IP) over low power and low bandwidth radio links.
Here we find an organization that develops standards for terrestrial cellular phone networks (3GPP) getting in on the act and developing standards for this internet of things using satellites, which they call IoT-NTN ("NTN" for "non-terrestrial networks").
When you run IoT communication over cellular networks (before getting to satellites -- regular cellular networks), that goes by the name "LTE-MTC", which as you see above, stands for "Long-Term Evolution Machine Type Communication". Don't ask me how cellular network standards came to be called "Long-Term Evolution", but that's what they're called. Tack on "Machine Type Communication" and now you're talking about machine-to-machine instead of human-to-human communication. How does this have to be modified to get it to work through satellites? That's what 3GPP's Release-17 answers. But this is Release-18.
Finishing out the abstract:
"IoT-NTN was further evolved in Release-18 and several performance enhancements were introduced. In this article, an overview of the Release-18 physical layer enhancements for IoT-NTN is provided. Specifically, a new feature related to disabling Hybrid Automatic Repeat reQuest (HARQ) feedback is described which helps mitigate the impact of HARQ stalling on throughput. Enhancements related to improving Global Navigation Satellite System (GNSS) operation are also discussed that enable the user equipment (UE) to maintain its uplink (UL) synchronization if its GNSS position becomes invalid during an ongoing connection. In addition, the performance evaluation of IoT-NTN technologies is presented in the context of International Mobile Telecommunications-2020 (IMT-2020) satellite performance requirements related to connection density."
So Release-17 came out in 2021, and Release-18 just came out, and Release-18 ties down some loose ends from Release-17. If you're wondering if "Global Navigation Satellite System" (GNSS) refers to the GPS system, the answer is... yes, but GNSS is actually a generic term for all GPS-type systems -- the US system is called GPS, Russia has a system called GLONASS (from "Globalnaya Navigatsionnaya Sputnikovaya Sistema"), China has a system called BeiDou, and the European Union has a system called Galileo. Japan has a system called the Quasi-Zenith Satellite System (QZSS), but rather than function as its own independent system, it's just a 4-satellite system that supplements the US GPS system around Japan.
Another loose end is HARQ, which stands for Hybrid Automatic Repeat reQuest. HARQ is a combination of an error-correction protocol and a system for requesting messages get repeated. With error-correction codes, additional bits are added to messages to enable errors to be detected and corrected -- within limits. If there are too many errors, however, the error-correction system gives up and the system requests the whole message be repeated. The "hybrid" part of "HARQ" is about how the HARQ system is a hybrid system that handles both -- error correction and message repeating.
The paper is paywalled, so I had to go searching on the internet to find out more. See below.

Täglich die Welt verbessern
Gestern hatte das weltweite Projekt Open Street Map (OSM) den 10. Geburtstag gefeiert. Am 9. August 2004 wurde die Domain fĂźr das Kartenprojekt registriert.
Eine Karte fĂźr die ganze Welt und das als freies offenes Projekt im Besitz aller Menschen. Das war damals kaum vorstellbar, aber es hat bis heute geklappt. Seit 2010 sind auch Aktive von Aktion Freiheit statt Angst e.V. dabei. Anfangs wurde schnell aus einem Punkt auf der Landkarte ein Ort mit StraĂen, Geschäften, SehenswĂźrdigkeiten, inzwischen sind es die AddOns, wie Bäume, Toillettenhäuschen, Recycling-Container u.v.m.
Bereits 2010 reklamierte das Projekt die Stadt Hamburg (fast) vollständig kartografiert zu haben. Inzwischen ist OSM weltweit (fast) flächendeckend verfßgbar. Der Vorteil gegenßber den käuflichen Produkten liegt nun gerade an der besseren Qualität und schnelleren Aktualisierung, denn die Nutzer greifen stets auf den aktuellen Status zu, während man bei gekaufter Software erst ein Updaten bestellen muss - und dazu oft den Kauf nachweisen muss.
Heise.de verweist auch auf die 1. Hilfe Funktion von OSM nach Katastrophen, denn schnell sind die vor Ort Aktiven von OSM dabei und bringen die Veränderungen, z.B. nach dem schweren Erdbeben in der Tßrkei vor einem Jahr, in die Karte ein und unterstßtzen damit die Hilfsorganisationen.
Inzwischen ist das Vertrauen in die Korrektheit von OSM Kartenmaterial auch so groĂ, dass Verlage sie fĂźr Spezialkarten, z.B. fĂźr Radfahrer und die Anbieter von ĂPNV sie zur Darstellung ihrer Online Fahrpläne nutzen. Auch das Navigieren fĂźr FuĂgänger, Radfahrer und auch Autos ist mit vielen Zusatzprogrammen, wie z.B. OSMand verlässlich mĂśglich.
Wir gratulieren diesem Open Software Projekt - und nutzen sie natĂźrlich auch selbst, z.B. zur Darstellung der Orte in unseren Terminen ...

"The flight from Madrid to Toronto is likely to have been deliberately targeted rather than being accidentally caught in the 'usual spillover' of electronic warfare, one analyst said."
"The suspected cyber attack happened in the northeastern Atlantic when a pilot reported being blocked from ascending to a higher altitude because the GPS (global positioning system) of the aircraft above them had been jammed, according to the Institute for the Study of War think tank."
"The cause of the jamming has not yet been identified, but GPS jamming has been recently reported over Poland and the Baltic region and attributed to Russian electronic warfare."
Article does not include the airline or flight number, as far as I could tell. Reading the article required me to register on the site and clicking 1 link casued me to hit a paywall. See before for my attempts to find out more.
GPS jammed on commercial flight over Atlantic for the first time
Catch #FareedZakaria 's #GPS on the repeat for his "My Take" segment & he comments further toward the end--but MY take on the Hindu nationalists love for the BJP is entirely part of the problem because traditional Hinduism was #apartheid where when you have only Brahmins ruling everybody else, it's the everybody else that's in the majority. Modi religiously thought Hindu nationalism was a good idea when it isn't and never will be.

The military relies on space for communications, for position, navigation and timing (PNT) information, meteorology, intelligence, surveillance, and reconnaissance. Australia now recognises space as an operational domain, alongside air, sea, land and cyber, and has established a Defence space command.
The Australian defence force already offers celestial navigation training and is working on a range of alternative navigation technologies.
It has a ânavigate using celestial aidsâ training unit that includes learning how to construct a sun compass to establish north, south, east and west; identify celestial bodies to determine south and north; and other methods to estimate direction, time, distance, and position.
So true though that the more we rely on vulnerable digital technology, we could be quite paralysed if it is neutralised. We rely on GPS for so many types of navigation, guidance, and even timing. Even technologies like cloud computing are no longer under local and decentralised control â such computing is not only exposed in the cloud but required long distance 24/7 connectivity to use.
Satellites are going to be great for phone calls in the wilderness, but such satellites too are very exposed in future warfare.
It is good to know some of the older tried and tested analogue skills are not yet lost. We do still have technologies such as ham radio that can establish communications over 10,000+ km without any Internet, and the newer Meshtastic license-free radio does a similar thing over shorter ranges.
It seems too that âolderâ tech low frequency navigation signals from ground stations may be coming back into use (a bit like short wave radio made a comeback for the war in Ukraine), and which are far more difficult to jam.

GPS spinnt, Duckduckgo zuckt mit den Schultern, erst "Beim Anzeigen der Suchergebnisse ist ein Fehler aufgetreten. Bitte versuche es noch einmal." mit einem Link mit dem Parameter errorRetry=1, bei dem dann einfach nur noch "Bitte warte ein paar Minuten, bevor du es erneut versuchst.". Was ist da los?
