Differential and RTK Operations 49
Differential and RTK
The receiver uses the six-of-eight format (data bits a1 through a 6 of an eight-bit byte)
for communication between the reference station and user equipment.
When the receiver is used as remote equipment and the RTCM and RTK remote
options are enabled, it can accept any type of RTCM message. However it decodes
types 1, 2, 3, 6, 9, 16, 18, 19, 20, 21, and 22 uses only types 1, 2, and 9 for differential
corrections and types 3, 18, 19, 20, 21, and 22 for RTK corrections. For radio
communication, the receiver in remote mode can recover bit slippage.
