0x5c - RTK Base Position - 25 bytes
SF-3050 Sapphire SF-3040
Message 0x5c, the NCT Proprietary RTK base position block, is extended to provide additional
precision and new information to support certain survey applications. W7 and W8 are added to
this block. The length of the block indicates the availability of W7 and W8.
On the rover side:
 NCT-2000D Products: If W1, B4 is set to “1”, the message is computed to W6. This shorter
message provides for backward compatibility.
 Sapphire and NCT-2100D Products: If W1, B4 is set to “0”, the message is computed to W8.

NCT-2000D Products: Software v3.2.10 and earlier will receive the older message where
W7 does not exist.
