1 QUICK START
This chapter will help you get started quickly regardless of whether you wish to carry out real-time kinematic
(RTK) positioning, operate in differential modes or simply log data. Each section references additional sources of
information.
1.1 INSTALLATION
For more detailed instructions on the installation and set up of your GPSCard please refer to the accompanying
MiLLennium GPSCard Guide to Installation and Operation.
The MiLLennium receiver is designed for flexibility of integration and configuration. You are free to select an
appropriate data and signal interface, power supply system and mounting structure. This concept allows OEM
purchasers to custom-design their own GPS-based positioning system around the MiLLennium GPSCard.
Installing the MiLLennium GPSCard typically consists of the following:
• Mount the GPSCard in a secure enclosure to reduce environmental exposure, RF
interference and vibration effects
• Pre-wire the I/O harness and the 64-pin DIN female connector for power and
communications, then connecting them to the OEM series GPSCard
• Install the GPSAntenna, then connect to the GPSCard
• (Optional) Install an external oscillator if additional precision and stability is required
OPERATION
Once the hardware and software installations have been completed, you are now ready to begin initial operation of
the GPSCard receiver.
Communication with the MiLLennium GPSCard consists of issuing commands through the COM1 or COM2 port
from an external serial communications device. This could be either a terminal or an IBM-compatible PC that is
directly connected to a MiLLennium GPSCard COM port using a null modem cable.
TURNING ON
The initial operating software and firmware of the MiLLennium GPSCard resides in its read-only memory. As
such, the unit “self-boots” upon power-up. The green LED indicator should blink about once per second if the unit
is operating normally. The red one lights up if an error is detected during a self-test. The self-test status word can
be viewed in the RGEA/B/D and RVSA/B data output logs.
If a persistent error develops please contact the NovAtel GPS Customer Service Department for further assistance
COMMUNICATION DEFAULT SETTINGS
COM1 and COM2 for the MiLLennium GPSCards are defaulted to the following RS232 protocol:
• 9600 bps, no parity, 8 data bits, 1stop bit, no handshake, echo off
Graphical Interface
Your GPSCard comes with a disk containing NovAtel’s graphical interface software GPSolution, a Microsoft
Windows-based program, enabling you to use your GPSCard without struggling with communications protocol or
writing make-do software.
