Introduction
About This Manual
This manual has been produced to assist the typical user with the installation
and operation of the OmniSTAR 8200HP DGPS Receiver.
System Features
The OmniSTAR 8200HP DGPS Receiver is part of the OmniSTAR world-wide
DGPS Service. The OmniSTAR service is a full-time differential GPS (DGPS)
broadcast system delivering corrections from an array of GPS reference
stations located around the globe. Reference stations provide industry
standard formatted corrections to Network Control Centres (NCC’s) at strategic
geographic locations, where the corrections are decoded, checked, and
repackaged in a highly efficient format for broadcast. The data is modulated
onto an RF carrier that is then up-converted for transmission to an L-band
communications satellite.
The signals are received at the user's location by an antenna, demodulated by
areceiver, and are made available, after selection of the desired individual
reference site's data set, as corrections for use in a GPS, differential-capable,
receiver.
The OmniSTAR 8200HP series of receivers support the following OmniSTAR®
services:
HP, this is the High Performance service where dual frequency GPS carrier
phase measurements are used in an intelligent and innovative way to create
wide area positioning results of unmatched accuracy and performance.
XP, this is the Extended Position service where precise orbit and clock data is
used to determine the position worldwide without using any reference stations.
VBS,this is the Virtual Base Station service where single frequency GPS code
phase measurements are used to create RTCM corrections data optimised for
the users current position.

Installation and Set Up
Installation Considerations
Before commencing installation of the OmniSTAR 8200HP in a vehicle or
aircraft, the following should be considered:
•Determine the preferred location for each unit. Consider cable length,
connector attachment space (cable bend radius), stowing excess cable,
moisture, chemical corrosion, vibration and heat exposure.
•Before drilling holes, consider using existing hardware and locations
where equipment was previously installed. Avoid drilling holes that may
damage other equipment (e.g. structural frame members, electrical
cables or fluid lines).
•High vibration and high temperature locations should be avoided
whenever possible.
•In application where vibration exceeds 5Gs acceleration, shock mounts
are required. (Refer to Customer support for mounting
recommendations).
•Vehicle primary power has voltages that may be harmful to personnel and
equipment. Disconnect the battery cable from the battery –Ve (negative)
terminal before making connection to any power terminal within the
vehicle.

Counter Electromagnetic Force (CEMF)
Apotential problem inherent in any installation of electronic systems within a
vehicle is Counter Electro-magnetic Force (CEMF).
CEMF is caused when relays or solenoids, connected to the vehicle DC power
distribution, are de-energised. The voltage produced may exceed – 400 volts.
CEMF is produced by equipment such as the following:
•Electric fan brakes
•Air conditioners
•Starter relays
•Electric pump relays
CEMF is more than sufficient to damage or cause erratic operation of any
electronic system that is also connected to the same vehicle DC power supply.
CEMF can be eliminated by installing diodes at the relays and solenoids that
cause the problem, and more importantly at the power supply cable
connections on the receiver.
A47V, 5W, Zener diode (1N5368 or equivalent) should be connected between
the receiver +ve (positive) power input terminal and ground, as illustrated in
Figure 3.

Cable Installation
Cables must be correctly installed for optimum system operation. Therefore,
the following should be noted:
•Do not route an L-Band receiver remote antenna cable with the cabling of
any other radio system. This may cause interference between both
systems.
•If at all possible, do not run L-Band receiver antenna cables parallel to
other radio system cabling closer than 30 centimetres.
•If cables must cross, ensure that they cross at an angle of
90°. This minimises the possibility of interference.
•As far as is practicable, ensure that cables and I/O connectors are unique
and fit only in their allocated location.
•Avoid routing cables along-side power generator cabling and other high
electrical noise sources. This can cause interference.
•Do not kink cables or force cables into sharp bends that may damage the
cables and cause system failure.
•After installation, ensure that excess cable is looped and clamped or tied
safely away from any control cables, fuel lines, hydraulic lines or moving
parts.
•When stowing over length cabling, form loops not less than 150 mm
minimum cable bend radius.
•Cable routing must avoid high temperature exposure
(e.g. exhaust manifold).

Features and Information
This section contains information on the features of the 8200HP receiver.
Strobes
On the 8200HP, a set of outputs that provide status and synchronisation
signals are given. These signals are called strobes. Access to the 8200HP
strobe signals can be obtained through both data ports.
The strobe available on the 8200HP is the One Pulse Per Second (1 PPS)
signal. The falling edge of this signal is synchronised with GPS time.
Receiver status
The 8200HP is equipped with an LCD display showing the status of the
receiver. Using the display and the buttons around the display, the receiver
can be configured without the need to connect a computer. The functions of
the LCD display and the configuration menus are described further on in this
manual.
Mounting the receiver
The 8200HP casing is equipped with four slotted mounting holes to facilitate
mounting the receiver to a surface. This section provides information on how
to mount the receiver.
Note: The receiver casing was not designed for mounting in high-dynamics or
high-vibration environments.
To mount the 8200HP receiver:
1. Using the slotted holes as a template, drill four holes in the mounting
surface.
2. Use screws to secure the casing to the mounting surface. When using
machine screws, tap the mounting holes to fasten the receiver to the
mounting surface. Alternatively, self-tapping screws can be used.
3. Make sure not to mount the receiver in a location where it can easily be
damaged during normal operation. Try to protect the receiver against
harsh environmental conditions.

Antenna Location
Antenna positioning is critical to system performance.
The following conditions must be met for optimum system performance:
1. Antenna must be mounted at least 1.5 metres away from transmitting
antennas of any frequency. Closer positioning may cause overloading of
receiver RF circuits.
2. The antenna should be mounted at the highest practical point that will
give a good view of the horizon and be as near level as possible.
3. The antenna must be located along the vehicle centre-line, or at a
relevant reference point on the vehicle.
4. The antenna should not be mounted in a location where it can easily be
damaged during normal operation.
Power Supply Requirements
The 8200HP can be powered by a vehicle or by a customer-supplied power
source of 10-32 VDC, capable of delivering at least 5W continuous output
power. For continued protection against the risk of fire, the power lead to the
8200HP receiver should be provided with a 10 A (maximum) fuse.
Warning: Before powering the receiver, make sure the antenna
cable and antenna are connected and the power/data
cable is connected and secured. Connecting or
disconnecting an antenna or antenna cable when the
receiver is already powered may permanently damage the
receiver’s antenna port or the antenna itself, voiding your
warranty. Connecting or disconnecting the power/data
cable to/from the receiver when the cable is already
powered may result in increased wear or an early failure of
the power/data connector.
Warning: If the voltage supplied is below the minimum specification,
the receiver will suspend operation. If the voltage supplied
is above the maximum specification, the receiver may be
permanently damaged, voiding your warranty.

Operating considerations
The 8200HP has proven to be a high-quality positioning device. The accuracy
that the user can obtain depends on several factors, including:
•Number of visible satellites
•Multipath
•Dilution of Precision (DOP)
•Satellite elevations
•OmniSTAR corrections
Number of visible satellites
Aminimum of four satellites is required to calculate a 3-dimensional position.
In general it can be said that every increase in the number of visible satellites
will result in an increase in the systems’ accuracy. As the GPS satellites orbit
the earth the number of visible satellites will change in time. The GPS
constellation has been designed to provide a minimum of 4 visible satellites at
any location at all times. The number of visible satellites can decrease due to
blockage by objects such as trees and buildings.
Multipath
It is possible for satellite signals to reflect off large nearby objects such as
buildings, cars or even the ground, thereby resulting in an erroneous
distance measurement. This phenomenon is known as multipath. Multipath
can cause significant errors in the position determination and it is therefore
important to place the receiver in an environment, which is free of large
reflective surfaces. It is also recommended to mount the receiver directly
onto a surface, while maintaining a clear view of the sky in all directions.

Position Dilution of Precision (PDOP)
The Position Dilution of Precision (PDOP) is a measure of the satellite
geometry. The closer to 1 the PDOP value, the more accurate the GPS
position will be.
Satellite elevations
The signal from a satellite that is low on the horizon will travel a greater
distance through the atmosphere. This results in a lower signal strength and a
delayed reception, thereby causing erroneous and noisy data. By default the
8200HP is configured to ignore any GPS satellites that have an elevation
angle lower than 5°for VBS and lower than 8°for HP.
OmniSTAR corrections
For accurate positioning it is essential that the differential corrections are
received. In order to ensure reception of the OmniSTAR satellite signal the line
of sight towards the satellite must not be blocked by objects such as trees and
buildings. To find out which OmniSTAR satellite(s) can be received at your
geographic position, please visit the surveyplanner website
(http://www.surveyplanner.com/).
Interference
Although the 8200HP has been designed to provide optimal system
performance under most circumstances, due to the nature of radio
communications it is possible, that the system performance degrades as a
result of local interference sources. When interference levels are too high, the
8200HP may even lose lock to either the OmniSTAR satellite or the GPS
satellites.
Interference sources include radio and television transmitters, radars,
microwave ovens, poorly shielded spark plugs and aeronautical
radionavigation systems, in short: any device producing electromagnetic
energy (directly or through harmonic frequencies) in the 1525 - 1580 MHz
band.

Operation
Before operating the receiver for the first time, ensure that you follow the
following installation instructions.
1. Mount the 8200HP receiver in a suitable place (see also page 9).
2. Mount the OmniSTAR antenna in a suitable place (see also page 10).
3. Connect the antenna cable to the antenna and the receiver, making sure
the right angle connector is connected to the antenna. Secure the
antenna cable using tie wraps.
4. Connect the data/power cable to port A of the 8200HP receiver. If
desired, also connect the data connector (9 pin sub D connector).
5. Connect the power leads to a suitable (10-32 V DC) power supply.
Getting Started
The purpose of this section is to get you started with the 8200HP as quickly as
possible. The guide will address receiving the satellite data carrier, and then
checking the functionality and status of the HP Process.
Generally, when the receiver is supplied to you it will be configured for the
mode and data link(s) you have subscribed to. In most cases getting up and
running will be a case of connecting the appropriate cables and applying power
to the system.
Communicating with the Receiver
Communicating with the receiver is possible using the receiver’s front panel
and LCD screen, the AgRemote program on a Microsoft Windows-based
computer or Viewall on a PDA. The AgRemote program will communicate with
the 8200HP through a standard serial port using the TSIP-protocol. AgRemote
will copy the front panel interface (LCD screen and buttons) to your desktop,
providing you with a familiar interface when the receiver’s front panel is hard to
reach. Because the 8200HP’s display is small, the receiver uses a number of
menus and submenus to access all of the receiver’s possible information and
configuration screens.
Starting the Receiver
The receiver’s software resides in read-only memory. As such, the unit “self-
boots” when turned on and undergoes a complete self-test. When the receiver
is first turned on, it will show the following boot sequence:
