Problem to get Ready status when using IM19 with GNSS Flex pHAT ZED-X20P

[PaulZC]

Hi @cgi27 ,

There is a lot of useful information in the post linked below. But I’m guessing you may have already seen it?

Sadly, you can’t test this on the table. The IM19 and GNSS antenna need to be physically coupled together, the antenna needs to be outdoors, and you need RTK Fix. Only when you have all three can you start the IM19 calibration.

Sorry! But that’s just the way it is. ‘Faking it’ with the antenna outdoors and the IM19 in the warm and dry doesn’t work…

Also, please check you are using the correct WORK_MODE. I’m not sure which one is going to be best for your application. Probably 72?

I hope this helps,
Paul

Help needed for Tilt Compensation setup using GNSS Flex pHAT ZED-X20P & IM19

Here’s what I have so far: GNSS Flex pHAT ZED-X20P on Raspberry Pi 5 running NTRIP Caster to my LAN over wifi GNSS Flex pHAT ZED-X20P & IM19 EMU on Raspberry Pi 5 running NTRIP Client connected by wifi Using PyGPSClient for configuration, monitoring, testing, etc. The base is mounted in a fixed position in my yard and the rover is currently mounted on a tripod. I have reliable RTK FIXED positioning. I have also been successful using SW Maps over Bluetooth. I am trying to set up Tilt Compensation, but have had no success so far. I enabled four UART devices on by Pi according to Software Overview - SparkFun GNSS Flex System Hookup Guide , but I don’t know why I need four… Why four? I am using the PyGPSClient UBX Configuration to set UART baud rates to 460800, and Preset UBX Configuration Commands to Enable NMEA High Precision. I also set the CFG_MSGOUT_NMEA_ID_GST_UART1 to 1, and checked that GGA and RMC messages are set to the default 1 values. I also used the recently added TTY…
