How to modify a field in a parsed RTCM message? #64
-
|
I'm parsing an RTCM message which results in a payload like the following: I want to modify fields DF025, DF026 and DF027, then re-serialize the message, but Python says the object is non-writable. Is there a way to achieve this in pyrtcm? |

Unfortunately there is no simple way to achieve this with pyrtcm. As the message says, RTCMMessage objects - once parsed - are immutable, as they are intended to represent point-in-time data received from an RTCM source. To create a new message, you'd have to construct a message payload from its constituent data bits. Purely out of interest, why would you be looking to modify the ECEF ARP coordinates in a 1005 message? Normally this would be generated by your calibrated NTRIP base station. |
