Hi Jan-Erik
It is the ION Institute of Navigation show in Fort Worth.
If you are GPS centric as we are it is a must attend.
We are hawking our GPS signal distribution products we have a line of
splitter amplifiers attenuators with special GPS doodads etc.
The code I've been working is for a GPS (L band) attenuator, GPS amplifier
(an attenuator with gain eh), a GPS re-radiator and a GPS calibrated level
signal source i.e. a poor man's GPS signal generator.
The attenuator and the amplifier have circuits that monitor the antenna
current (too high or too low causes an error).
They also have circuits that monitor the RF level for antenna oscillation[s]
(a common failure mode for a GPS antenna is for its preamp to become an
oscillator you will see extreme RF levels out of it when this failure
occurs) if I detect an oscillation I cut power to the antenna force a user
intervention.
 
The GPS re-radiator (GPSRK) has the same basic functions as above but
includes a GPS receiver in it to controll the transmitted ERP automatically.

 The calibrated level signal source is basically a GPSRK but has greater
dynamic range and finer control.
They all are controlled with buttons on the front panel and via a serial
port.
Next revision is of course USB control as fewer and fewer computers are
available with serial ports.
After that it is a blue tooth link to GPSRK as they are generally mounted in
the rafters/overhead.

I'll have another company to run soon so I'll be farming out most of the USB
and blue tooth stuff or hiring someone full time...Colorado is nice area.

I gotta run Anna is here and she looks great in her little black dress.

Thanks again to everyone for all your help and patience.
 
Phillip

Good luck with the show !
And let us know what the people there thought
about, well,  whatever it is you're doing... :-)

Jan-Erik.
