BB60C GPS Timestamp Receive Problem

[blackmore90]

Hello,
I am trying to obtain timestamp samples of the GPS data using a BB60C and a Xenith TBR. I have made the 1PPS and 10MHz RX-GPS connections and the RS232 connections to PC from both devices. On the GPS, lock and antenna LEDs are green. The problem is when I try to run the code attached, I receive seconds and nanoseconds fields with zero value. The code is mostly from the manual, only with a replacement of bbQueryTimeStamp to bbGetIQ due to command deprecation reasons. I cannot get the correct timestamp value.

Any help will be appreciated.

Hello blackmore90,

What happens if you call the bbGetIQ function a few more times, (call it in a loop for a few seconds) I believe it requires at least 1 PPS signal from the GPS before it can start accurately time stamping data.

(And I’m assuming you have checked the return values of the functions to verify they haven’t thrown any errors)

Regards,
Andrew
