Russia plans to rival U.S. GPS system
Winston,
Right now I have an armada of gps receivers that work with the US DoD
satellites. Will I have to buy entirely new equipment for the
gallelio and glonass systems? Or will there be a receiver that
integrates =all= available signals into one unit? How is this going
to work. I'm interested as I have a considerable investment in the US
equipment.
Lg
I think the US system will keep on being used and your equipment will
receive it as usual. After all, it's basically there for the military
and there are huge transportation industry investments in it.
The new systems have to be different in some way or they would
interfere with each other. I'm sure new receivers will come on the
market to receive them. One, two or all three.
It will be the consumers choice in the future which one you want to go
with very much the way you choose one cell phone provider and not
another or one satellite TV system over their competitor.
Not to fear, what you have should keep on keepin' on.
This is a big relief. Thank you Winston, and Terryc.
As a sidenote, the US gps system is subject to radio interference from
solar storms. Unfortunately, during a solar storm, the same radio
frequency spectrum the gps receivers in the US use are overlap the
radio interference from the solar flareup. This can and has in the
past, resulted in communications interruptions and in the case of gps,
denial of service.
The next solar activity of this kind is expected around 2011 or 2012.
Some solutions have been suggested, like making the satellite signals
stronger, but that would mean a new fleet of enormously expensive
hardware. Time will tell what happens.
