Am I correct that you are asking how much bandwidth is needed in order to send real time corrections to a Reach unit?
I did some bandwidth testing quite a while ago for radio links, but things have changed since then.
The answer will depend on several factors:
- If receiving third party corrections, then your provider should have this information
- If you are pushing the corrections yourself, then you must consider the:
- Number of satellite constellations enabled on the base,
- Number of RTCM3 messages types enabled on the base,
- Frequency of those messages,
- The update date of the base.
