Hello Michael,
Re: setting GPS data formats
As I mentioned previously, my GPS unit works perfectly with the TAC32
evaluation software. I can see the NMEA sentences on the screen every
second. In addition, the 1 pulse-per-second is working, and so is the
10 kHz output. So, I have a working GPS system. I can proceed from
there to build up the 10 MHz Oven Stabilized Oscillator and complete the
GPS Disciplined Oscillator.
I think you pointed out that this GPS unit defaults to the Navman Binary
mode. I have tried to use HyperTerminal via a serial port and about all
I see is @@EA followed by a burst of random characters every second. I
tried 4800 and 9600 baud. I would like to be able to read the NMEA
sentences (GPGSA, etc) so I can use Day, Date, Time and 3D Fix for other
purposes. To do that I think I need to change the format of the GPS
output data. (From Navman Binary to ????)
I am still uncertain about how to send commands to my TU60-D120-041 GPS
unit. I have spent hours trying to understand serial communication with
GPS units and I haven't had much luck. You mentioned that you developed
some software that would accomplish that. Any help would be greatly
appreciated.
Thank you, 73, Jerry - WA0ACF
