Quick Start

MiLLennium GPSCard Software Version 4.50 Command Descriptions Manual Rev 1

Establishing differential mode of operation at the rover receiver is primarily a one-step process whereby the accept
command is used to enable reception of observation data from the reference station.

ACCEPT COMMAND

The accept command is primarily used to set the GPSCard’s COM port command interpreter for acceptance of
various data formats (see the

command in Chapter 2, Page 23 and Appendix C, Page 79).

Syntax

Example:

accept com2 rtcm

Once intitialized, the rover GPSCard receiver will operate in single point mode until the differential messages are
received. If the data messages are lost, the GPSCard will revert to single point positioning until the pseudorange
correction messages are restored.

NOTE:

Ensure that the GPSCard

RTCMRULE

settings agree with the bit rule being transmitted by the

RTCM

reference station. Unless otherwise set, all GPSCards default to 6CR.

LOG POSITION DATA AND OTHER USEFUL DATA

The GPSCard remote receiver has many options for information data logging. To monitor position status, the user
may find the

PRTKA

logs to be the most informative. Other options exist, such as

POSA

and

GPGGA

. As well,

velocity data can be found in the

VLHA

SPHA

and

GPVTG

logs. It is really up to your specific applications as to

the full range of logs you require.
