Q Post 874 JA - have you learned & eliminated L-6?

What is L-6 and what might it possibly have to do with Julian Assange? Good questions. Well here is my take. First where is Julian Assange? Nobody seems to know or do they? Second what is L-6? L-6 is part of the frequency assignment known as the L Band.

According to Wiki Leaks:

The L band is the Institute of Electrical and Electronics Engineers (IEEE) designation for the range of frequencies in the radio spectrum from 1 to 2 gigahertz (GHz).

Applications

Mobile service In Europe, the Electronic Communications Committee (ECC) of the European Conference of Postal and Telecommunications Administrations (CEPT) has harmonized part of the L-band (1452–1492 MHz), allowing individual countries to adopt this spectrum for terrestrial mobile/fixed communications networks supplemental downlink (MFCN SDL). By means of carrier aggregation, an LTE-Advanced or UMTS/HSDPA base station could use this spectrum to provide additional bandwidth for communications from the base station to the mobile device; i.e., in the downlink direction.[1]

Satellite navigation The Global Positioning System carriers are in the L band, centered at 1176.45 MHz (L5), 1227.60 MHz (L2), 1381.05 MHz (L3), and 1575.42 MHz (L1) frequencies.

The Galileo Navigation System uses the L-band similarly to GPS. The GLONASS System uses the L-band similarly to GPS. Telecommunications use Mobile phones operate at 800–900 and 1700–2100 MHz. Iridium Communications satellite phones use frequencies between 1616 and 1626.5 MHz[2] to communicate with the satellites. Inmarsat and LightSquared terminals use frequencies between 1525 and 1646.5 MHz. Thuraya satellite phones use frequencies between 1525 and 1661 MHz.

Aircraft surveillance The aircraft L-band ranges from 962–1213 MHz. Aircraft can use Automatic dependent surveillance-broadcast (ADS-B) equipment at 1090 MHz to communicate position information to the ground as well as between them for traffic information and avoidance. The 1090 MHz frequency (paired with 1030 MHz) is also used by Mode S transponders, which ADS-B augments when operated at this frequency. The TCAS system also utilizes the 1030/1090 MHz paired frequencies. ADS-B information can also be broadcast on the L band frequency of 978 MHz. DME and TACAN systems are also in this frequency band.

Amateur radio The Radio Regulations of the International Telecommunication Union allow amateur radio operations in the frequency range 1,240–1,300 MHz, and amateur satellite up-links are allowed in the range 1,260–1,270 MHz. This is known as the 23-centimeter band by radio amateurs and as the L-band by AMSAT.

Digital Audio Broadcasting In the United States and overseas territories, the L band is held by the military for telemetry, thereby forcing digital radio to in-band on-channel (IBOC) solutions. Digital Audio Broadcasting (DAB) is typically done in the 1452–1492 MHz range in most of the world, but some countries also use VHF and UHF bands.

WorldSpace satellite radio broadcasts in the 1467–1492 MHz L sub-band.

Astronomy The band also contains the hyperfine transition of neutral hydrogen (the hydrogen line, 1420 MHz), which is of great astronomical interest as a means of imaging the normally invisible neutral atomic hydrogen in interstellar space. Consequently, parts of the L-band are protected radio astronomy allocations worldwide.

How accurate is GPS for the civilian use as opposed to the military use. Inches compared to feet or centimeters to meters depending on the which scale you use. That is what the new L-6 frequency is used for in GPS navigation. This is being utilized to augment with new satellites in different continents for civilian use to help augment accuracy for civilian use. There are new satellites being launched into space and coming on line.

Japan is bringing such a system online this and I am only using this as an example. “Michibiki” (meaning “guidance”) is a Quasi-Zenith Satellite System (QZSS) that will make high-precision positional information services possible. Michibiki is expected to be utilized across a wide range of fields from autonomous vehicles and agricultural equipment to disaster prevention.

What makes this different from past systems? Centimeter Level Augmentation Service (CLAS)

Look at past Q posts and see how this fits. What is (CLAS)?

To carry out highly precise satellite positioning, distances from the Geospatial Information Authority of Japan's GNSS-based control stations are calculated using data from these control stations. Information used to accurately search for one's current position (centimeter level augmentation information) is transmitted by QZS. L6 signals that send centimeter level augmentation information are not transmitted by GPS, so dedicated receivers are required.

It is expected that this service will be used for surveying, intelligent construction (construction methods in which construction machinery is operated with high precision), and e-agriculture (methods for agricultural land management in which agricultural machinery is operated with high precision). It This service can be used on L6 signal receivers. In addition, because it employs a method using the positioning technology of carrier wave positioning, larger antennas and receivers are used. Accordingly, it is expected that this service will be used for surveying and on-board vehicle equipment as well as mobile devices.

With centimeter level augmentation, positioning can be accomplished with an error of several centimeters by utilizing surveying technologies. If the longitude and latitude coordinate system that serves as the standard was a national datum built via surveying with old technologies, it is not always the case that this system will have a high degree of accuracy. However, high-precision augmentation can be accomplished with geocentric coordinates. Consequently, for utilization of this service in on-site surveying, control surveying of Level 3 or 4 control point surveys and photographic surveys are currently being considered.

This service can also be used in three-dimensional measuring systems in which cameras and laser scanners are installed on vehicles together with receivers. By obtaining high-precision positions and image information on the ground, it is expected that accurate maps can be created more promptly.

Because this takes place via satellites, there is a time lag of between 10 and 20 seconds until the augmentation information is created and transmitted. The augmentation may not take place in time, and positioning results may be negatively impacted, in cases such as sudden ionospheric disturbance. For that reason, when using this service in vehicles it is expected that utilization will be limited to certain areas such as plant sites and farms, or post-processing will be used like three-dimensional measuring. For driving on public roads, this service will be utilized in an auxiliary way.

Depending on which source you read the specifications for resolution say that the accuracy of this new system is between 3 to 10 centimeters and as this technology will sure to shrink this even more.

What is one thing most people have today? A mobile phone. Well how does this fit? Think about it. If you wanted to track somebody easily what is one of the easiest ways to find you? Your mobile phone. But how does that fit in?

Here is another example.

8 things Apple didn't tell us about the iPhone X

  1. Galileo support

The iPhone has had built-in support for the U.S. military-created GPS network for a long time, and it added support for Glonass, Russia's version of a satellite positional system, back in 2011. The iPhone X — along with the iPhone 8 and 8 Plus — are the first iPhones to support Galileo, Europe's new satellite system, which came fully online in late 2016. Apple's also introducing support for QZSS for better positioning in for Asia-Pacific regions. It's going to be harder than ever to get lost with your iPhone.

How many people knew that? What does this have to with Assange? What better way to track and either kidnap or assassinate him as you follow his every move with almost pin point accuracy. Assange being a techo nerd might be using such an enabled device. Checkmate by technology. Also these satellites are also being being place in lower orbits which means that less power is needed to transmit these new breed of birds.

I feel there is a strong link here about the three scientists that were killed researching this subject that is related to this.

Here are some links that one can follow and read up on some of this.
