STS message
Posted By birol Gucluer on 10/16/2001 at 11:26 AM

Hi all Ashtech People
I am an Ashtech GPS user. I am working on a GPS GIS integration project for RTK applications. I will collect NMEA (POS,RRE,SAT) messages and analyse it in MAPINFO and deciBel Planner. There is one more important message to analyse --STS message. It will give me the Ambiguity Fixing Contrast Ratio. Because it is not a NMEA, I can not receive it continuously (i.e. 1 per second). Is there any message that gives a information CPD solution that can be got continuously.
All the Best

No, because CPD is computed at 1Hz.

Birol,
It's true that the $PASHR,CPD,STS message can't be set for periodic output, but if your data logging software can be made to generate the $PASHQ,CPD,STS query at a 1Hz rate, you can still get the STS every second.
STS is the only message that contains the AFC ratio information, but you may want to investigate using the $PASHR,CBN message for some valuable solution information. CBN can be set for periodic output with the $PASHS,OUT command. The output interval is tied to the raw data RCI interval. See page 125 in Z-Family manual for more information, or contact Ashtech tech support [mailto:support@ashtech.com] if further assistance is needed.
