can't get RTK on rover #8
Comments
Moreover: I noticed that as soon as I shutdown the ROS node, the module enters in RTK mode. |
I'm using the zed-f9p.yaml file.

Hi. I'm a beginner at Localzation, and the same problem happend(RTK is enabled on Zed, but not on c099-f9p) Have you made any Progress or resolution? Please let me know if you have. |
Has this problem been solved? I have the same one. |
Which Problem do you have? Explain details plz. For your info, i use this package |
Hi Jeong,
Thanks for your reply.
The main issue I think is getting the corrections through the server. I
connect but do not receive anything. I found out today that is necessary to
send NMEA messages in order to get corrections (at least here in Croatia).
However, I do not know how to do that yet. I guess the same ntrip client
node has to deal with that, right?
Can I ask you about the order you run it? I mean, do you launch first the
ublox zed-f9p node and later the ntrip node to get corrections?
Thanks and regards,
PhD Eugenio Alcalá

Hi Eugenio You should fill in 'URL, PORT, USER_ID, USER_PASSWORD, MOUNTPOINT' information I obtained this information from a government department related to geographic information in Korea, but you can use services from your country or free services. I hope this is helpful to you. Jeong Boin |
@boing-86 안녕하세요 혹시 rtcm값을 받았을 때 rostpic echo로 입력했을 때 stauts값이 0이 아니라 1이나2 등 바뀌는 값으로 들어오나요?? |
@dbparkJ 제가 ROS 개발 손 놓은지 몇 년 되어서 잘 기억은 안나지만 몇 가지만 여쭤보고 싶습니다.
|
@boing-86
(2)위 사진과 같이 /ublox_gps/rtcm을 echo했을 때 값이 수신되고 있습니다.
메시지 api document는 따로 확인하지 못했습니다... 다만 u-center(windows기반 어플리케이션)에서는 ntrip_client셋팅하여 status 값에 5(Fixed RTK) 값이 들어오는 것을 확인했습니다. 추가적으로 제가 사용한RTK는 https://www.gnssdata.or.kr/rtcm/getRtcmView.do 이 방식으로 현재 파주와 양주 관측소에 RTCM-32를 사용했습니다 마지막으로 명절중에 답변 주셔서 다시한번 감사합니다. |
@dbparkJ u-center 부분에서 이해가 가지 않는 부분이 있어서 여쭤봅니다. 그리고 현재 보유하신 기기에서 fixed 상태를 의미하는 led 가 켜지나요? 다른 질문들도 추가여쭤봅니다

@boing-86 아니요 ㅠㅠ 해결은 하지 못하고 대신 위성을 더 많이 사용해서 오차는 조금 더 줄어든 것 같습니다 |
제 생각에 이 레포 관련 문제가 아니라 외부 요인으로 인해 to-be 가 충족되지 않는 것 같습니다. |
I correctly installed the package and I launch it with: roslaunch ublox_gps ublox_zed-f9p.launch as described in the readme.
The problem is that my C099-F9P rover board never enters in RTK mode.
I can get the RTK mode if I connect it to windows while running u-center.
Is there any option I need to add in the config file?
thank you!
