It is a pleasure to share our latest achievement C-RTK2 HP with you. Only one module is needed to realize yaw GPS, and support more frequency bands to achieve high-precision positioning.
Its features:
One module has two antennas, GPS positioning can realize GPS yaw.
Low cost and high performance: under the same performance, the cost of use is lower than that of F9P modules
Support high-precision RTK, RTK error minimum 0.8cm
Support UART and Drdoncan, ArduPilot provides source code.
Built-in industrial grade RM3100 compass, supports GPS yaw and compass redundancy.
AP4.4.0 stable firmware can run C-RTK2 HP perfectly.
In order to communicate better, I publish this post to collect feedback and suggestions from all users.
Can we use this module, along with Here3, I want dual redundancy,
I want to use C-RTK2 HP as my primary source for Yaw, and I want to use here3 as a backup.
Is it possible to use both the module together,
if Yes, please tell me how to do that.
I am trying to do that but did not succeed …
Sorry, I don’t own here3. But I think it can work simultaneously with here3, one thing to note is that you first need to check which GPS is set as GPS1 by ArduPilot, when C-RTK2 HP is set as GPS2, you should set GPS_MB2_XXX instead of GPS_MB1_XXX.
Hello @cuav_le
I am facing an issue with C-RTK 2HP PreArm: waiting for home, the drone is not able to lock the home position.
The drone has 28+sat,
it’s under a open sky,
the FC recorgnizes the GPS…etc
This error is occuring randomly, and once it occur, we are not able to arm in GPS mode.
I think @kalai1219 is also facing the same issue. Can you please help us out
HI
When i set EK3_SRC1_YAW to 3(Gps with compass fallback) my drone is not able to fix its position eventhough it has 28 sat , when i change EK3_SRC1_YAW to 1 (compass) the position is fixed instantly . what to do for this .help me out
