Reference Station Health - ashtech DG16 Reference Manual

Reference Station Health

You may set the reference station to unhealthy, which causes all remote
receivers to ignore the messages they receive from that base station.
Other RTCM Messages
Partial Differential corrections: Message 9
These are alternatives to messages 1. They should only be used if you have a
low bandwidth data link (~100bps). Use of high-bandwidth data links, and
messages 1 are recommended.
Message type 1 cannot generate at the same time as type 9.
Message 2
These are automatically generated when the base station is transmitting
differential corrections and a new ephemeris is downloaded from the
satellites.
Filler: Message 6 Null Frame
This message is provided for data links that require continuous transmission
of data, even if there are no corrections to send.
Special Message: Message 16
This message allows you to transmit an ASCII message from the base
station.
Using a PC Interface
If you are using the Thales Evaluate™ software to interface to your receiver
you may use initialization files (
commands for you.
To monitor the corrections from a PC, turn on the MSG message
$PASHS,NME,MSG,y,ON
This generates an ASCII representation of the RTCM messages transmitted
by the base station and decoded by the rover. Use different receiver serial
ports for MSG and the actual transmitted RTCM messages.
The DG16 can accept differential corrections from a SBAS satellite, through
the beacon receiver, and/or through a serial port input. You can select the set
of corrections you want to use in the navigation solution (Integrated
Differential Optimization or a single type of correction data).
