ION Southern California Section December Meeting

Torrance, CA

The Southern California Section of the Institute of Navigation’s December meeting will take place at the John Deere facility in Torrance, CA on December 15, 2015.

Dr. Chun Yang will speak at the meeting.  The title of the talk is Sharpening Peak Performance of GPS Signals. In this talk, the variable IF tracking architecture that improves the
peak performance will be presented together with possible implementation
schemes. Simulation results will be used for illustration and analysis.

The USNO master clocks control GPS timing. They are accurate to within one second every 20 million years (Satellites are so picky!

Failure to Communicate

Failure to Communicate

For an organization with its name, the Federal Communications Commission (FCC) is a remarkably opaque public entity. 

Such is the case with the agency’s inaction on requests by foreign GNSS services to waive the so-called FCC Part 25 rules that require licensing of non-Federal receive-only Earth stations (e.g., GNSS receivers) operating with non-U.S. licensed space stations (i.e., satellites). 

Although at least one such request has reportedly been submitted, the FCC has not even acknowledged it, let alone moved to render a decision on the request.

Code Shift Keying

Equations 1 – 10

The constant growth and evolution of the positioning, navigation, and timing (PNT) market generate demands for more and more added-value applications and services relying on GNSS signals, with expectations for improved accuracy and availability. Some services may also rely on added-value content other than navigation messages, for example, higher data volume with less latency, such as the data carried by satellite-based augmentation system (SBAS) services and the Galileo Commercial Service.

How Important Is It to Synchronize the Code and Phase Measurements of a GNSS Receiver?

How Important Is It to Synchronize the Code and Phase Measurements of a GNSS Receiver?

Q: How Important Is It to Synchronize the Code and Phase Measurements of a GNSS Receiver?

A: Precise timing lies at the heart of GNSS implementation and operation and is generally well understood in terms of synchronizing individual satellites and/or receivers. Recent results, however, have demonstrated that timing of code and phase measurements in a receiver can have significant implications for the timing community in particular.
