Timing pin

For my application, I need pseudoranges and a 1pps timing pin. Does the NS-RAW also has a 1pps timing pin? Or do I need to get the timing module for that? Its a little confusing because all the documentation states they all are Venus 8, but each module seems to only expose certain functionality.

Pseudoranges

Is the NavSpark capable of outputting pseudoranges?  I purchased a couple a while back thinking they might have this capability.  Now that I'm finally playing with them, I'm not seeing pseudoranges available in any of the messages.

Occasional very long acquisition time - NavSpark-GL

Several times, my NavSpark-GL has failed to acquire satellites for a period of many hours. Normally, it will acquire (after a restart or a software load) in a minute or two. When it fails, the GNSS Viewer shows a date from 2006, and show no satellites at all on the Earth View. I have tried a "Warm Start" which sets the time correctly, but it still shows these symptoms. It is showing: Boot State: ROM(OK) (I have the factory boot jumper installed) SW Version: 2.0.2 SW Revision: 2013.2.21 All…

Why Is Speed Noisy at Higher Update Rate ?

SkyTraq's GPS/GNSS has fastest update rate in the low-cost consumer/industrial segment.

GPS modules has 50Hz maximum update rate.

NavSpark has 10Hz maximum update rate, reserving enough throughput for application development. Firmware at bottom of NavSpark product page on the web-store also supports 50Hz maximum update rate for NavSpark, 20Hz for NavSpark-BD and NavSpark-GL.

Often users want to use highest update rate regardless of application, and sometimes this gives…

More NS-T Programmable Frequency Testing

Although NS-T generated frequency lock accuracy is better than 10^-11, there is phase jitter. This experiment tries to clean up phase jitter with $2 PLL : http://www.digikey.com/product-detail/en/PI6C4511WE/PI6C4511WE-ND/1305452. PLL used has output minimum of 2X input frequency, so 10MHz input will have 20MHz output, 19.2MHz input will have 38.4MHz output. Jumping wire to…

"Indeed it has been a while since last update. Will have update later next week fixing below points:
1. Add vertical speed to GNSSSpeed
2. Make NMEA talker ID GP as default for NavSpark-BD and NavSpark-GL, so it'll work with most existing GPS applica…"

"Hi,
If anyone is interested in a pre-built MAX21100 board with other bits , this one is quite nice and small - https://www.tindie.com/products/onehorse/max21100-motion-sensor-wit... .
Cheers,

"Those firmware images are just compiled versions of the default firmware, right? When do you expect that you will have an update that will let us build custom Arduino code and operate above 19km?"

"Yes it is possible to use NAVSPARK RAW with RTKLIB on Linux or Windows any other OS that RTKLIB has been ported to.
Here is an example about using RTKLIB: http://www.navspark.com.tw/blog/tutorial-using-ns-raw-with-rtklib-r..."
