A TRIMBLE STANDARD INTERFACE PROTOCOL (TSIP)
146 Copernicus GPS Receiver
Report Packet 0x4B - Machine/Code ID and Additional Status
The receiver transmits this packet in response to packets 0x25 and 0x26 and following
a change in state. In conjunction with Packet
0x46, “health of receiver,” this packet
identifies the receiver and may present status messages. The machine ID can be used
by equipment communicating with the receiver to determine the type of receiver to
which the equipment is connected. Then the interpretation and use of packets can be
adjusted accordingly.
The status codes are encoded into individual bits within the bytes. The bit positions
and their meanings are listed in the table below.

This packet provides the current value of the receiver master oscillator offset in Hertz
at carrier. This packet contains one single precision number. The receiver sends this
packet in response to Packet
0x2D. The permissible offset varies with the receiver
unit.
