M3 GPS INSTALLATION MANUAL Revision D PAGE 1

SECTION ONE

Technical information

Scope of this manual

This manual describes the physical, mechanical, and electrical characteris-

tics of the Northstar M3 GPS, included with the installation instructions.

Operational information is found in the Northstar M3 GPS Approach Ref-

erence Manual (Part No. GM601), which is supplied with the unit.

Equipment description

The Northstar M3 GPS consists of a panel-mounted GPS receiver-naviga-

tor, mounting tray, and GPS antenna. The unit is approved under

TSO-C129, Class A1. Use of the M3 is subject to airworthiness approvals

limited to en route, terminal area, and non-precision approach operation

under Visual Flight Rules (VFR) or Instrument Flight Rules (IFR). See

Appendix B, STC Certificate SA00464NY (as ammended), for Federal

Aviation Administration (FAA) Field Approval reference; and Appendix

C, FAA-Approved Airplane Flight Manual Supplement (AFMS, formerly

known as the Supplemental Air Flight Manual), for specific limitations

and operating procedures under the STC.

The unit receives radio signals from GPS satellites and calculates its lati-

tude and longitude from these signals. The unit’s database is contained on

a user-changeable FliteCard™. It provides the coordinates of thousands of

airports, VOR and NDB transmitters, airway intersections, and routes and

approaches.A variety of navigation functions may be performed using this

data.

Interfacing the

Northstar M3 to

other equipment

The unit may be interfaced directly to many Course Deviation Indicators

(CDIs), Horizontal Situation Indicators (HSIs), Flight Directors, and/or

autopilots. Outputs also are provided to drive panel-mounted annunciators.

The unit also may be interfaced, through its built-in serial data port, to

devices like fuel-management systems, moving map displays, or other

devices designed to meet the Northstar serial data format described in the

Northstar Serial Data Format Specification V1.19 Firmware, Revision 2.2

(Part No. GM342). This document can be ordered by calling Northstar

Avionics.

Section One—Technical Information

PAGE 2 M3 GPS INSTALLATION MANUAL Revision D

The M3 may be interfaced to an altitude encoder, either by connecting the

individual encoder wires directly to the M3 or by using a Northstar 2006

Altitude Serializer. Altitude information enhances GPS accuracy and

availability. Interfacing an encoder is recommended for all installations

and is required for IFR-approved installations. Instructions for installing

the serializer are in the specifications in the Northstar 2006 Altitude Seri-

alizer Installation Manual (Part No. GM435), which is included with the

serializer.

SECTION TWO

Installation instructions

General information

This section contains information for installing and wiring the Northstar

M3 GPS, antenna, and interfaces.

All installation procedures should follow acceptable practices, methods,

and techniques as described in Advisory Circulars (AC) 43.13-1A and

43.13-2A.

Special installation

requirements •Before inserting or removing the M3 from the mounting tray, turn off

power to the tray using the avionics master switch or circuit breaker,

even if the unit’s power switch is turned off. This will prevent inrush

current from arcing across the power connector.

•Use only a GPS antenna specified within this manual. Only the

Northstar AN120, AN135, and AN155 antennas are approved for use

with the M3. Consult the factory for special applications not covered

in these instructions.

•The GPS antenna must be mounted on the top of the aircraft.

•The GPS antenna should be located at least two feet away from any

other antennas and from the vertical stabilizer and canopy.

•Forced air cooling must be supplied to the unit for all installations.

•Electrical noise suppression of existing equipment may be required to

obtain satisfactory performance.

Make sure all parts are present and have sustained no shipping damage. If

there is evidence of shipping damage, save the shipping carton and pack-

ing materialto help substantiate your claim to the shipping company. Keep

a shipping carton on hand in case you have to return the unit to the factory

for service.

Preparing the antenna cables

Choosing the

antenna coax To connect the antenna to the GPS sensor, use RG-58 C/U coaxial cable

(Alpha No. 9058C or equivalent). The outside diameter of the cable must

be approximately 0.24 inches to be compatible with the supplied connec-

tors. For a typical RG-58 cable loss of 23 dB per 100 feet at 1500 MHz,

the cable length between the antenna and sensor should be at least 10 feet

and not more than 50 feet. If the antenna cable is routed near sources of

high electrical energy, then it is recommended that double-shielded coax

be used to reduce radio-frequency interference. Shields should be

grounded at both ends of the cable.

Type RG-59 coaxial cable is also acceptable. For typical RG-59 cable loss

of 18 dB per 100 feet, the cable length should be at least 15 feet and not

more than 80 feet.
