SBAS and RNSS: The Unsung Heroes of GNSS
Okay, if I had wanted to pander to GNSS fans, I might have called this, “Making Great Greater.”
But there are only so many superlatives that can be lathered on this remarkable technology before simple praise turns into hagiography.
So, it’s time once more to give a little love to those unsung heroes of GNSS: the augmentations and regional navigation satellite systems.

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

Working Papers explore the technical and scientific themes that underpin GNSS programs and applications. This regular column is coordinated by Prof. Dr.-Ing. Günter Hein, head of Europe’s Galileo Operations and Evolution.
With the support of the European Space Agency (ESA), a European team designed a frequency- and time-transfer process and validated its performance in a complex navigation test bed. This two-way time-transfer technology took advantage of the following:

Figure 1, 3, 4 & 5Q: What is Doppler collision and is it a problem in GNSS?
A: Doppler collision is a physical effect in code-division multiple access (CDMA) systems where code measurement errors are observed due to cross-correlation effects. Doppler collision may occur when the Doppler frequency between signals from two different transmitters is smaller than the code lock loop bandwidth.

The GPS Aided Geo Augmented Navigation (GAGAN) system was developed by the Indian Space Research Organization (ISRO), together with Airports Authority of India (AAI), to deploy and certify an operational satellite-based augmentation system (SBAS). The system’s service area covers the Indian Flight Information Region (FIR), with the capability of expanding to neighboring FIRs.
