SECTION ONE

Introduction

The Northstar 2201 and 2201/NMEA Installation Manual

describes how to properly mount, interface, connect, and

troubleshoot the Northstar 2201 and Northstar 2201/NMEA.

Also described are their physical, mechanical, and electrical

characteristics.

This section explains who should read this manual, how to

obtain technical support, and how to return a 2201 or 2201/

NMEA for servicing. Also described are some of the standard

features of the 2201 and 2201/NMEA, and all of their operating

modes.

In this manual, unless otherwise stated, the term “2201” refers

to the 2201 and the 2201/NMEA.

Welcome to the

Northstar 2201

and 2201/NMEA

The Northstar 2201 WAAS Pod and the Northstar 2201/NMEA

WAAS Pod are self-contained, high-performance GPS antennas/

engines that also receive WAAS (Wide Area Augmentation

System) differential correction signals. These corrections

enhance position accuracy to a degree previously unavailable

with separate beacon differential receivers.

SECTION ONE Introduction

Page 2 2201 INSTALLATION MANUAL, Revision B

Understanding the 2201

and 2201/NMEA

The 2201 is available in either of two configurations:

•2201 (binary output) — for interfacing with new and

existing Northstar 941X/XD, 951X/XD, and 952X/XD units

in order to provide WAAS differential corrections. (In the

future, the 2201 will be able to interface with Northstar’s

961X/XD and 962X/XD.)

•2201/NMEA (NMEA) — for interfacing directly with

autopilots, plotters, components of integrated or

standalone marine navigation systems that accept NMEA

0183 data, or NMEA 0183-compatible laptop PC’s, in order

to receive WAAS differential-corrected GPS position data.

Understanding WAAS

satellite differential

As with Coast Guard radiobeacons, WAAS satellites use

surveyed reference stations to monitor GPS signals from each

visible satellite and determine if errors exist, and then develop

corrections. However, unlike Coast Guard radiobeacons or

other land-based transmitters on other frequencies, WAAS uses

a network of geostationary communication satellite

transponders, in fixed positions at approximately twice the

distance from the earth’s surface as the orbiting GPS satellites,

on the same frequency as GPS.

These satellite-based transmissions provide consistent position

corrections over a much greater contiguous geographic

location than the other radiobeacons. WAAS differential

corrections maintain a position accuracy of better than 3

meters 2dRMS, without the signal interference problems

periodically experienced with low-frequency, shore-based

radiobeacon differential signals.

NOTE: For the binary 2201 to provide WAAS corrections to

a Northstar 941, 951, or 952, these units must be

running software version 3.18 or higher. To obtain

an Upgrade CD and a PC loader cable (Northstar

part number 1100-LC), dealers should contact the

Northstar Sales Department. End users should

contact their local Northstar dealer for upgrading.

For the complete listing of the 2201’s specifications, see

Appendix A at the back of this manual.

2201 operating

modes

The 2201 has seven automatic operating modes:

•Self-test

•Initialization

•Acquisition

•Navigation (includes three sub-modes: Differential 3-D,

Differential 2-D, and 3-D Nav)

•WAAS/beacon differential

•Dead-reckoning

•Fault

The 2201 automatically switches between modes, and reports

through its host port the current operating and navigation

modes. The seven operating modes are described in detail

below.

Self-test mode The 2201 enters self-test mode upon a host’s request, using an

NMEA or binary message, via the GPS primary port. This test

requires no more than 15 seconds. When the self-test is

completed, the 2201 reports the test results on its host port

through another NMEA or binary message, and then either

proceeds to initialization mode if the test was passed or to fault

mode if a problem was detected.

Initialization mode The 2201 enters initialization mode automatically when power

is applied or after completion of the self-test mode. While in

initialization mode, the 2201 retrieves satellite orbital data

(ephemeris or almanac) stored in its EEPROM memory.

Integrity checking is performed on all data retrieved from the

EEPROM to ensure accuracy. After initialization, the 2201

enters acquisition mode.

SECTION ONE Introduction

Page 8 2201 INSTALLATION MANUAL, Revision B

Acquisition mode The 2201 enters acquisition mode whenever sufficient

real-time satellite data is available to produce an initial

navigation solution. Acquisition mode can be entered from

initialization, navigation or dead-reckoning mode. The 2201

exits either to navigation mode when satellites have been

acquired or to fault mode if a problem is detected.

After each satellite in view is acquired, the 2201 collects new

ephemeris data by decoding the satellite downlink data

message. When a sufficient number of satellites are being

tracked, position, velocity and time are computed, and the 2201

enters navigation mode. If the 2201 can’t acquire signals

normally due to an absence of valid almanac data, it initiates a

“Search the Sky” acquisition, attempting to acquire any and all

satellites in the GPS constellation. After a satellite has been

acquired, ephemeris data is decoded from the satellite’s

down-link message. In “Search the Sky,” the Time-To-First-Fix

(TTFF) is typically less than two minutes. After a sufficient

number of satellites have been acquired, the 2201 enters

navigation mode. For TTFF details, see Table 1, “2201 and

2201/NMEA technical specifications,” on page 31.

Navigation mode The 2201 operates in navigation mode whenever sufficient

satellite information and measurement data are available to

produce a GPS fix. Navigation mode is entered from either

acquisition or dead-reckoning mode, and exits to

dead-reckoning or fault mode.

Navigation mode has three sub-modes (the 2201 automatically

chooses the highest-performance sub-mode available for the

satellite data currently being received, and reports the current

navigation sub-mode to its host port):

•differential 3-D

•differential 2-D

•3-D nav

Differential 3-D mode

The 2201 operates in differential 3-D mode when it receives

data from at least four satellites with adequate geometry and

differential corrections, from either WAAS satellites or

radiobeacons, via SC104 data supplied on the AUX INPUT port.

This is the navigation mode with the highest performance.

SECTION ONE Introduction

2201 INSTALLATION MANUAL, Revision B Page 9

Differential 2-D mode

The 2201 operates in differential 2-D mode when it receives

data from only three satellites with adequate geometry and

WAAS or external radiobeacon differential corrections. This is

the navigation mode with the highest performance when

differential 3-D mode can’t be used.

3-D Nav mode

The 2201 operates in 3-D nav mode when it receives data from

at least four satellites with adequate geometry, but no

differential corrections. This is the preferred navigation mode

when sufficient WAAS or external radiobeacon differential

corrections aren’t available.

WAAS/beacon differential

mode

The 941/951/952 has four options for setting the binary 2201’s

WAAS and radiobeacon differential operations:

•auto (the default setting) - for automatically using WAAS,

but the 2201 will revert to beacon differential if WAAS

becomes unavailable and external beacon corrections are

applied through the port.

•WAAS - forces WAAS only

•radiobeacon - forces beacon differential only

•disabled - turns off differential corrections

After connecting the 941/951/952 with the 2201, to select one

of these options, see “SECTION FOUR Using WAAS with

Northstar’s 941/951/952” beginning on page 25.

For information on using the 2201 with external SC104 data,

contact the Northstar Service Department.

Dead-reckoning mode The 2201 enters dead-reckoning mode when navigation mode

can’t be maintained. The speed and direction are assumed

constant, based on the last-known data, to allow the 2201 to

provide an estimated position.

Fault mode The 2201 enters fault mode if it determines that the its outputs

are affected by one or more critical system faults. This mode

supersedes all others and remains active until the next

power-down/power-up cycle. Fault mode can be entered from

any other mode (except initialization) whenever an

unrecoverable fault is detected. Fault mode prevents inaccurate

data from being transmitted.
