[App_rpt-users] RTCM Question

The RTCM can be used as a simple radio interface without GPS by simply
setting the RTCM GPS Polarity to 'NONE'.

 

10 - GPS PPS Polarity (0=Non-Inverted, 1=Inverted, 2=NONE) (2)

Subject: Re: [App_rpt-users] RTCM Question

 

I have a slightly off-topic question regarding the RTCM in this
configuration. I have been wanting to use my RTCM in a mobile application
such as this. There is a section in the RTCM manual which describes
configuring the RTCM as a non-voted, non-simulcasted client. One would think
that a GPS reference wouldn't be needed for something like this where the
data is not time-sensitive, but app_rpt and chan_voter don't seem to want to
work without a GPS sync (even for a standalone "simple radio interface" as
described in the manual). If the RTCM's can't even be used as simple radio
interfaces without a GPS, than that may need to be documented in a much
clearer fashion to avoid confused, unhappy customers who are expecting to
use the RTCM as a simple, standalone radio interface to app_rpt.
Thanks for reading, 
Paul

application, but good luck getting a 3G device these days :)
