I am feeding my C94-M8P Development Board with RTCM V3 Messages from an Online Ntrip Caster. This caster sends RTCM V3 messages 1004,1005,1008,1012,1029,1030,1031,1032,1033. Unfortunately, the C94-M8P supports 1005, 1007,1007,1009,1010,1011,1012,1074,1075,1084,1085,1087,1124,1125,1127 and 1230.
1. With this Setup, I get the rover into RTX Float Mode with only message type 1005. Do you know which messages are mandatory to reach RTK Fix Mode? Is there any possibility to extend the supported message types on the Ublox module?
Furthermore, with another test setup, I am feeding RTCM V3 messages from an external base station (Novatel O638) into the C94-M8P Rover. Unfortunately, the Novatel O638 Base Station doesn't support message type 1230, which prevents to Rover to go into RTK Fix Mode although we're sending messages 1004,1077 and 1087.
2.Is message 1230 mandatory for RTK Fix Mode?
3. Would it be a better test setup to feed an Ublox Base Station with RTCM V3 data and send the correction data to the Rovers from the Ublox Base station or is this not a better option than feeding the RTCM V3 data straight to the Rovers from the Caster or Novatel Base Station.
Thank you very much for your help!
