By Inside GNSSEvery so often, anthropologists — and maybe a few mathematicians — have a field day puzzling over the origins of our positional base-10 numeral system.
Oh, not the historical origins themselves, the Hindu-Arabic innovations beginning in the 5th and 6th centuries. That’s all pretty much agreed.
No, I’m referring to the possible physiological inspirations, the readily visible digits at the ends of our limbs: 10 fingers, 10 toes.
Coincidence? Does nature have coincidents, or does it abhor them like vacuums — o horror vacui?

As a navigation satellite transmits multiple signals on single frequency (e.g., Open Service and Restricted Service over L5 Band), these are combined on a common carrier to comprise a composite signal. This composite signal passes through navigation payload subsystems such as an up-converter, traveling wave tube amplifier (TWTA), filters, and so on. These subsystems may introduce adverse effects on the signal, such as amplitude and phase distortion, nonlinear effects, gain imbalance, IQ imbalance, and phase noise.

The Indian Regional Navigation Satellite System (IRNSS)] is designed as a stand-alone regional navigation system with a primary service area extending up to 1,500 kilometers from the Indian land mass. Finland lies north of 60°N latitude more than 5,000 kilometers away from India, as shown in Figure 1 (see photo at the top of this article).

Topcon Positioning Group has announced that its latest GNSS reference receiver has tracked a new signal from the GLONASS constellation.
The GLONASS-M 55 satellite was launched in June and is equipped
with an experimental payload capable of transmitting CDMA signals in the
Russian GNSS system’s L3 frequency band centered at 1202.025 MHz. According to the company, Topcon engineers successfully tracked the signal using the NET-G5
receiver during a series of recent tests at the Topcon Technology Center
in Moscow, Russia.
Tallysman has introduced the TW5340 “smart” antenna that pairs Tallysman‘s Accutenna technology with STMicroelectronics’ Teseo II GNSS receiver.
The TW5340 is a multi-constellation GNSS antenna that provides simultaneous GPS/GLONASS/SBAS reception and is designed for use in professional grade applications such as precision timing, network synchronization, or low-current and tracking/positioning applications.

Swiss-based u‑blox launched its new EVA‑M8M stand-alone positioning module today (November 6, 2014), bringing concurrent multi-GNSS capabilities into the company’s compact EVA footprint.
Technology to counter the threat of GNSS jamming is now available at Dover and along the east coast of the United Kingdom as the island nation continues to implement an enhanced Loran (eLoran) system that is setting an example for the world.

Prodded by Congress, the federal government is reexamining its decision to abandon eLoran, a network of ground stations capable of supplying essential timing and positioning data to power, phone, and other critical networks if something happed to GPS.
