Miscellaneous
For some reason, for example you are using your receiver in
conjunction with older equipment, you may need to revert to
V1. This is possible using the $PASHS,ATM,VER command
(see ATM,VER: Setting the Version of ATOM Messages on
page 156).
The history of the ATOM format can be summarized as
follows:
• 2009: First official release of ATOM (V1 version)
• 2011: Second offcicial release of ATOM (V2 version).
ProMark 800 is the first commercial receiver to benefit
from this new format version.
For more information on the ATOM format, please refer to the
ATOM Reference Manual (P/N 631648).
Time-tagged RTK vs. FAST RTK Position Output
Your receiver can deliver RTK positions either in Time-Tagged
or Fast RTK mode. The default mode is Fast RTK.
If you wish your receiver to operate in Time-Tagged mode, use
the appropriate serial command to switch into that mode (see
CPD,FST: RTK Output Mode on page 170).
In its standard version, the receiver features a Fast RTK mode
with an output rate of 2 Hz. With the FASTOUTPUT firmware
option, the output rate is 20 Hz. After purchasing this option,
use the $PASHS,OPTION command to install it. See
OPTION: Receiver Firmware Options on page 209).
