INTRODUCTION
The 3200LR12 receiver consists of both a 12-channel GPS receiver
and a L-Band differential receiver built into a single unit. It provides
differentially corrected positions at update rates up to 5 times a
second through two independently configurable RS-232 I/O ports.
Position accuracy is typically less than one metre and the receiver is
suitable for both ground and air applications. Three LED indicator
lights give operational status at a quick glance. The receiver can
have a one-pulse-per-second output signal synchronised to GPS
time.
The 3200LR12 receiver is easily configured using TSIP commands.
Baud rate, position update rate, common NMEA string output and
binary data output are among the variables which can be controlled
using the TSIP commands. More detail on these commands is
provided in a later section and in the View 3200 software Manual.

GPS/DGPS Introduction
The Global Positioning System (GPS) is a reliable, continuous, all-
weather navigation system, which is operated by the United States
Government. At the time of writing, the space segment of GPS
includes a constellation of 28 satellites, which orbit the earth at an
altitude of approximately 22.000 km.
These satellites (Space Vehicles or SV’s) transmit radio signals
containing precise satellite time and position information. By
receiving four or more of these signals a 3-dimensional position can
be computed.
Although GPS provides an acceptable level of performance for
some users, many applications demand a more reliable and precise
position than GPS alone can provide. In such cases Differential
GPS (DGPS) must be used.
The purpose of DGPS is to minimise the effects of atmospheric and
satellite errors on the position determination. In order to achieve this
areference GPS receiver must be installed at a point of known co-
ordinates. This receiver uses the radio signals from each of the GPS
satellites, which are in view to measure so-called pseudo-ranges to
these satellites. Because the exact locations of the satellites and the
reference receiver are known, it is then possible to determine the
difference between the actual and the expected pseudo-ranges
(pseudo-range correction or PRC).
In order to provide compatibility for exchanging this correction data,
astandard has been developed by the Radio Technical Commission
for Maritime Services Special Committee 104. This standard is
commonly known as RTCM SC-104.
When RTCM version 2.0 correction data from the reference receiver
is applied to a nearby GPS receiver, the position accuracy will be
substantially better than if stand-alone GPS were to be used.

The OmniSTAR system
The 3200LR12 is one of several DGPS receivers which have been
designed to work with the world-wide OmniSTAR service.
The OmniSTAR DGPS system delivers corrections from an array of
reference stations, which are located all around the world (see
appendix C). The RTCM correction data from these reference
stations is provided to OmniSTAR’s three Network Control Centres
(NCC), where the corrections are decoded, checked, and
repackaged in a highly efficient format for broadcast.
The OmniSTAR data is broadcast over a series of L-band
communication satellites. The signal transmitted over each of these
satellites contains the corrections from the reference stations in and
close to the region in which this satellite can be received.
When a receiver with a valid subscription receives data through one
of OmniSTAR’s satellite channels it will output a differentially
corrected position. The way in which the correction data from each
individual reference station will be used in the position calculation
depends on the user’s OmniSTAR subscription.
Subscription type
The 3200LR12 supports the following OmniSTAR service:
•Virtual Base Station (VBS), where the data from multiple
reference stations is used in the processor software to
produce enhanced corrections for the user's location. This
service provides optimal position accuracy with a minimum
dependence on the user’s location. The VBS service can be
obtained on a continental, country or regional basis.
