Minimizing power consumption

Hi I have a use case where I want to leave an NS-RAW on the greenland ice sheet during the polar night to record to SD for as long as possible (months to half a year). I expect temperatures to drop below -50C and there is a real problem with most batteries. So I want to minimize power comsumption to an absolute minimum. My initial imperfect measurements indicate i would need in the order of 250Ah with the latest firmware.  GOAL: I would really like to be able to detect very small changes in…

NS-RAW and Adapter-Board

Hi there, maybe you can give me some support. My questions: right, that there is no way of accessing the logs on the SD-Card via USB, only by transferring the SD-Card to some SD-Card reader respectively to the PC? How to flash the modified adapter code for logging on SD? Is there something like bootload, or only possible via Ardui no environment, I am not familiar with Arduino, some instructions would be very very helpful. What where the parameters in RTKPOST to achieve cm-accuracy with logged…

Problem with sparc-elf-mkprom

Hello! I try to port the adafruit 10dof library from arduino to navspark. I already change the wire functions by TwoWire, but when I try to compile my example, the program sparc-elf-mkprom crashes, without any error message. What I doing wrong? Thanks and sorry for my english. Adafruit_10DOF.cpp Adafruit_10DOF.h

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…

After several hours my Navspark-BD loses its position fix. It stays like that for several minutes. Eventually it recovery and shows a fix again. I haven't moved the receiver at any time. Several satellites are in view.Is this a normal behavior? How…

"Colin,
really great to get a such detailed and therefore very helpful response to my questions. I'll keep looking for your results, which would push my project forward. My project is on combining wristband sensor data (psychophysiological responses…"

"Giorgos, I think you are correct about transferring files off of the SD-Card can only be accomplished via an external card reader.  I asked a similar question about the RX and TX pins on the board as I wanted to use them to communicate with the NS-R…"

"Yes, need to move SD card to PC in order to read.
Use GNSS Viewer to update the firmware:http://www.navspark.com.tw/blog/ns-raw-firmware-update-with-sd-card...
RTKPoST should have similar settings as using RTKNAVI:http://www.navspark.com.tw/blog/tut…"

"Thanks for the update. Does it have to do with the orbits of 5 and 6? Their doppler shifts should be larger than the doppler shifts of the actual constellation. I can imagine that makes tracking difficult."
