Im making progress with my GNSS compass, but i wondering about krakenSDR CSV line
11 GPS heading
12 Compass Heading
13. Main Heading GPS/Compass
I guess line 13 is just to input Compass, but for 11 and 12, what is the difference?
Please tell us more about your project. Will you use one GNSS antenna or two. I am currently working on a compass with two GNSS antennas.
Its just under testing. Its not rocket science, you need 2 GNSS receivers, and a esp32, why i have esp32 is because its having built in wifi. And cheap. The technical is that you calculate the angle bwtween 2. So one receiver is forward of the car and one aft. And little code, and what im hoping for is that esp32 can upload position and heading to krakensdr. Then i can stand still with my car and always have good heading and position. If its going to work, well i see soon…
Have you already tried to make an accurate calculation of the course and distance between GNSS antennas on the ESP32? I use the Arduino DUE in my experiments and it calculates the distance in 288 milliseconds and the direction in 51 milliseconds. To perform accurate calculations, I use the GPS64 library. When calculating, I use the high-precision mode, since this is very important at short distances.
GPS and compass headings are used to differentiate between the two sensors. For most mobile phone deviceas we can log the heading via GPS and compass at the same time. So you can switch between the two depending on what you think was more accurate during your measurements.
Line 13 just tells you what the user selected as the heading sensor during the measurements, so that sensor is used as the preference for display. As some devices might only have GPS and no compass etc.
