So I have been playing with the NS-RAW for several months....

... and still don't have cm accuracy. I use high-gain Tallysman 3040 antennas, multiple sats received, although NS-RAW only receives the GPSS sats (not GLONASS or Beidou)....and generally can get an OCCASIONAL "fix" solution with RTK, mostly float, and mostly "floating" (meaning they wander all over the place).  I have tried about every switch in RTKLib, without success, and am coming to the conclusion that cm-level accuracy is a nice dream, but not attainable. Anybody else have an idea?

Garbled Serial Output

I just bought a standard Navspark, and attempted to just get serial output from the board. I set up the IDE (64 bit Linux), and uploaded a Hello World program: void setup()  {     Serial.begin(9600);  } void loop()  {    Serial.println("Hello world!"); } It uploads successfully, but when I open the Serial Monitor I get a whole bunch of garbled text, like "BB!cXJ������)�T i�VFy...". The monitor is set to the correct baud rate, the processor is set to the one without GNSS library (I've tried…

Miniature RTK Receiver

Interesting small-size RTK receiver running RTKLIB powered by Intel Edison: https://www.indiegogo.com/projects/reach-first-affordable-rtk-gps-receiver Our own RTK receiver is under development. It'll automatically discard unusable satellite signals without user intervention. Using good antenna and with baseline less than 4Km, GPS L1 RTK should have fixed solution within 5 minutes if having 8 or more usable satellites, GPS L1 + Beidou B1 should have fixed solution within 3 minutes if having 12…

Problem running adaptor board example code

Hi, I’m trying to write some text to a sdcard with the Navspark adaptor board. With my Navspark GPS I tried to run this example code: https://store-lgdi92x.mybigcommerce.com/content/SD_Card_Access_Example.zip Compiling and uploading works fine, but when I run it nothing is written to the sdcard. After some quick debugging I’ve noticed the code crashes when it tries to make a folder on the sdcard: FRESULT res = fatFsAgent.make_dir(folderName); I’ve connected al the pins of the adaptor board…

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…

Arduino in its current version 1.6.4 supports several non-Atmel processors through its boards manager. Edison, Galileo and ESP8266 are among those. Any idea when you will be moving up to the new Arduino boards manage…"

"Did you try resetting the board? I often get garbled output, which is fixed after I press the reset button. Guess something doesn't get properly synced before."

Jason Lin replied to Jeroen's discussion Problem running adaptor board example code
"Hi Edwin, 
   The underlying SPI interface access method for NavSpark is different from standard Arduino, thus likely the Arduio SD-Card library cannot directly be used even if pins are mapped.
   NavSpark GPIO[31:28] are connected to the SD card as…"
