NOTES

Trimble SCOUT M GPSReceiver

The Trimble SCOUTM receiver is a small, hand-held,battery-powered GPS receiver with three channelscapable of tracking up to eight satellites simultaneously.With the receiver you can determine position, navigate,and store positions. Positions are stored individually (aswaypoints) in memory. The receiver holds up to 100positions in battery-backed up memory. The SCOUTM+

can store up to 250 waypoints, with 26 routes of 20 legseach.

The receiver contains all the position and navigationfunctions expected in a full-featured GPS receiver. Itsupports Military Grid Reference System (MGRS),Universal Transverse Mercator (UTM), Ordnance Surveyof Great Britain (OSGB), and Latitude/Longitudecoordinate systems. It provides navigation functions suchas range, bearing, and cross-track error. The receivercontains 123 datums, including two additional user-defined datums.


2 22370 - Rev. C

The SCOUTM receiver operates in seven languages:English, French, Italian, German, Japanese, Norwegian,and Spanish.

Your receiver has a built-in antenna (above the displayscreen underneath the Trimble Navigation "sextant"logo) that receives signals from all GPS satellites that arevisible from your position. Hold the receiver so that thelogo is flat to the horizon, with a clear view of the sky.The receiver will automatically sort through and lockonto the strongest signals in view from horizon tohorizon. (See Appendix E for an illustrated parts list foraccessory kits.)

The signals received from the satellites allow thepowerful microprocessors in the SCOUTM receiver tocompute the precise distance from the best satellites toyour location, and through basic geometry, locate you inthree dimensions: your exact earth coordinates andaltitude. The exact time for your location is alsocalculated.

In addition, when moving, your receiver preciselycomputes your speed of advance and direction of travel.Simply insert the coordinates of important map positionscheckpoints, targets, obstaclesinto the waypointmemory, and you are ready to start navigating. TheNavigation screen (NAV) incorporates a CourseDeviation Indicator (CDI) as a steer-to indicator, givingyou a visual representation of your position in relation toyour desired track.

The Global Positioning System

The Global Positioning System (GPS) is a major militarysatellite-based, radio navigation system developed by theU.S. Department of Defense (DoD). GPS consists of24 satellites in 12-hour orbits. The satellites emit signalswhich can be tracked by receivers for positioning andnavigation. The GPS system provides day and night, all-weather, worldwide, 24-hour navigation capability.


22370 - Rev. C 1

Equipment Care

The Trimble SCOUTM receiver has a robust design andshould serve you well in all climates and militaryenvironments. As with most electronic instruments, youshould exercise prudent care and treat this precisionnavigation device with respect. Here are a few helpful hintsfor care and handling.

• When not in use, secure the Trimble SCOUTM receiver inthe carrying case and slip it into your pocket, or otherprotected location.

• Use the lanyard provided to avoid accidentally dropping thereceiver.

• Do not immerse in water or solvents. Use a damp cloth toclean the unit. Use a lens brush to clean the window of sandor other material that could cause scratches.

• Keep charged batteries installed at all times to maintainthe waypoint and satellite almanac memory.

• Cut out the Quick Reference Card, found in the front of thismanual. Fold and place in the carrying case pocket.

• Fill out and mail the warranty card, found in the front of thismanual. The serial number of your receiver is located insidethe battery compartment.


2 22370 - Rev. C

Batteries

Four AA batteries power the SCOUTM receiver. Batteries canlast up to 20 hours at four position fixes per hour (intermittentoperation), and up to 5 hours continuous use when using themaximum update rate.

Replace batteries whenever you see the Batteries lowreminder and before storage.

It is important to store the receiver with fresh batteries to savememory. If the receiver is left without batteries for more than30 minutes, all memory may be lost. When storing theSCOUTM receiver for an extended period of time, install afresh set of batteries. If unused, the batteries will maintain thememory for over a year.

NOTE: Because battery life is variable, it's a good idea tohave an extra set of batteries on hand wheneverplanning extended use of your SCOUTM receiver.


22370 - Rev. C 3

To install batteries:

1. Turn the receiver over.

2. Press the battery pack latch down while sliding out thebattery pack.

3. Install new batteries by following the diagram inside thebattery pack. (If batteries are installed incorrectly, thereceiver may malfunction or be permanently damaged.)

Battery Installation

4. Slide the battery pack in until the lock engages.

5. Reset the battery timer. See Reset Hours in the MoreUses Screen section.

SCOUTM GPS Keypad

Keypad

The Trimble SCOUTM receiver is operated from a simple,eight-position keypad. The receiver is self-initializing; that is, itwill automatically locate its position anywhere outdoors in theworld, without user inputs. So, just turn it on. The SCOUTM

does the rest.


22370 - Rev. C 5

Power On and OFF

Power On

The SCOUTM receiver ON/OFF key, located at thebottom of the keypad, has a unique tactile feel for low-lightoperation. One press powers up your receiver.

information which can be viewed at any time. (Just makesure that you hold down the ON/OFF key less than4 seconds.) The bottom left side of the screen shows howmany satellites are being tracked, each satellite indicated bya symbol.

The battery usage is shown on the bottom right. You shoulduse the Reset Hours command to reset this each timebatteries are changed. See the procedure in the More UsesScreen section. Also shown on this line is the almanacwarning, which is covered later in this section.

If the key is released during the countdown, the SCOUTM

receiver returns to the previous screen.

To skip the 4-second countdown, press W while pressing theON/OFF key.

When the SCOUTM is turned off, all user-input settings,waypoints, and the satellite almanac are maintained involatile memory. If batteries have been removed for morethan 30 minutes, memory may be lost.


22370 - Rev. C 7

Satellite Almanac Collection

The first time you use your Trimble SCOUTM receiver, or ifthe batteries are dead, or if it has been a long time since usingthe receiver, you may have to allow the receiver to read thelatest almanac of information from the satellites. It takes atleast 12.5 minutes of continuous reception to collect theentire almanac from scratch, but almanac updates areregularly read and stored in memory whenever the receiver isbeing used.

2D or 3D solution and accuracy

In normal operation, the SCOUTM uses signals from four satellitesto provide position fixes in three dimensions, including altitude. Ifonly three SVs are available, the calculated positions are twodimensional (no altitude); the labels for data items related toaltitude flash alternately with the message 2D. In this case, theaccuracy of the fix depends

on an accurate estimate of the altitude, whether from the previous3D solution or operator entry. The altitude shown should beverified or changed by the user.

If the SCOUTM has been receiving signals from four SVsand loses contact with one of them, it switches from 3D to2D operation. When 3D fixes resume, the SCOUTM resumesdisplay of the GPS-calculated altitude.

Entering an Altitude to Aid 2D Fixes

If only three satellites are available, the calculated positions aretwo dimensional (no altitude). In this case, the accuracy of theposition fix depends on an accurate estimate of the altitude,whether from the previous 3D fix or by manual entry.

Coordinate Style

Coordinate systems are used to describe a position on eartha curved, three dimensional surfacein a way that can betranslated to the flat surface of a map. The SCOUTM

receiver offers a choice of five coordinate styles:

• MGRS - Military Grid Reference System (default setting)

• Lat/Lon Minutes (Latitude/Longitude Altitude)

• Lat/Lon Seconds

• OSGB - Ordnance Survey of Great Britain

• UTM - Universal Transverse Mercator

Because each coordinate system resolves your position towithin less than 100 meters, no particular system is moreaccurate than another. Your choice is determined by personalpreference and access to maps or other geographicalinformation.

The Trimble SCOUTM receiver prime (or default) coordinatestyle is the Military Grid Reference System (MGRS).

Once preferences are set, they remain until changed or theSCOUTM receiver is without battery power for longer than30 minutes. At this point, the receiver will automaticallydefault or reset to the prime style for coordinates and allother default settings.

UTM Coordinates - Universal Transverse Mercator

The UTM coordinate system is typically used ontopographical maps. It is a worldwide coordinate grid thatcan be used anywhere between 84° north and 80°southlatitude. Positions are shown in terms of how far north andeast they are from a given reference point. This is known asnorthing and easting.

Mapping Datums

A datum is a mathematical model of the earth's shape used bycartographers to draw maps. For the GPS-computer positionto agree with a corresponding position on your map, thedatum you select must match up with the datum used tocreate the map. This datum is usually found in the maplegend or title block on the map.

A list of the 123 datum options and two user-defined datumswithin the SCOUTM receiver is shown in Appendix A. Manymodern U.S. maps are based on the WGS-84 datum, which isthe default setting in your SCOUTM receiver.

To change your datum to correspond with your map datum

1. From the SETUP index screen, select the mapping datumscreen.

Appendix C - Glossary

2D, 3D Two-dimensional and three-dimensional positions.A 2D position fix provides coordinates in twodimensions, such as latitude and longitude. Elevationis assumed to be fixed. Only three satellites arerequired to provide a 2D position with a user-suppliedelevation. A 3D position provides the elevation inaddition to LAT/LON and requires four satellites.

Almanac A reduced-precision subset of the ephemerisparameters. Used by the receiver to compute theelevation and azimuth angles of the satellites. Eachsatellite broadcasts the almanac for all the satellites.

Azimuth Angle The angle of the line-of-sight vector,projected on the horizontal plane, measured clockwisefrom north.

Channel Receiver hardware that is required to lock to asatellite, make the range measurements, and collectdata from the satellites.

Datum or Mapping Datum A mathematical model of theearth. Many local datums model the earth for a smallregion, for example: Tokyo datum, Alaska, NAD-27(North American). Others, WGS-84, for example,model the whole earth.

Differential GPS (DGPS) A positioning technique thatuses two receivers: one (the roving receiver) at anuncorrected location, and the other (the referencestation) at a known, fixed location. The referencereceiver computes corrections based on thedifferences between its actual and observed ranges tothe satellites being tracked. These data are transmittedto the roving receiver. The coordinates of theuncorrected location can be recomputed with greatprecision by applying these corrections.

Elevation Mask The elevation angle below which asatellite is considered unusable. It is used to prevent

the receiver from searching for satellites which areobscured by buildings or mountains.

Ephemeris A set of parameters that describes a satellite'sorbit very accurately. It is used by the receiver tocompute the position of the satellite. This informationis broadcast by the satellites.

GDOP, PDOP, TDOP Geometric Dilution of Precision,Position Dilution of Precision, and Time Dilution ofPrecision. GDOP describes how much an uncertaintyin range affects the uncertainty in position. The GDOPdepends on where the satellites are, relative to theuser. A large GDOP means that a small error in rangewill translate into a larger error in the position.

GDOP has two components (TDOP and PDOP).TDOP determines the uncertainty in the clock bias;PDOP determines the uncertainty of the position.PDOP is composed of HDOP and VDOP and typicallyhas good values between 2 and 7. See HDOP.

Geoid The actual physical shape of the earth, which is hardto describe mathematically because of the localsurface irregularities and sea-land variations.

GPS The Global Positioning System, consisting of theNAVSTAR satellites in six different orbits, GPSground-control stations, and the user community.

GPS Time The length of the second is fixed and isdetermined by primary atomic frequency standards.Leap-seconds are not used as they are in UTC.Therefore, GPS time and UTC differ by a variablewhole number of seconds.

HDOP, VDOP The horizontal and vertical components ofPDOP. They describe how an uncertainty in rangeaffects the horizontal position (latitude and longitude)and the vertical position (elevation). For 2D position,HDOP is the only important component.

Latitude, Longitude A topocentric, spherical coordinatesystem, whose coordinates are latitude, longitude, andelevation. Latitude and longitude can be expressed asdegrees, minutes, seconds (DMS), or as degrees,decimal minutes (DM).

L1 The primary L-band signal radiated by eachNAVSTAR satellite at 1575.42 MHz. The L1 beaconis modulated with the C/A and P codes and with theNAV message. L2 is centered at 1227.60 MHz.

Monitor Station One of five worldwide stations maintainedby the DoD and used in the GPS control segment tomonitor and control satellite clock and orbitalparameters. Corrections are calculated and uploadedto each satellite at least once per day.

NAV Data The 1500-bit navigation message broadcast byeach satellite at 50 bps on both L1 and L2 beacons.This message contains system time, clock correctionparameters, ionospheric delay model parameters, andthe space vehicle's ephemeris and health. Thisinformation is used to process GPS signals to obtainuser position and velocity. 2

NMEA-0183 A standard established by the NationalMarine Electronics Association (NMEA) that defineselectrical signals, data transmission protocol, timing,and sentence formats for communicating navigationdata among marine navigation instruments.

Pseudorange A measure of the range from the receiver'santenna to the satellite. Pseudorange is obtained bymultiplying the speed of light by the apparent transittime of the signal from the satellite. Pseudorangediffers from actual range because the satellite and userclocks are offset from GPS time and because ofpropagation delays and other errors.

Relative Positioning The process of determining the vectordistance between two points and the coordinate of onespot relative to another. This technique yields GPSpositions with greater precision than single-pointpositioning mode.

Rise/Set Time The period during which a satellite isvisible, that is, has an elevation angle above theelevation mask. A satellite is said to rise when itselevation angle exceeds the mask and set when theelevation drops below the mask.

RTCM SC-104 Radio Technical Commission for MaritimeServices standard defined for generating pseudorangecorrections and transmitting them from referencestations to differential stations.

22370 - Rev. C F - 1

Appendix F - SCOUT M+Enhancements

The software and hardware on the Trimble SCOUTM+ allowfor the use of a direct-connect antenna and an RS-232dataport. (See Appendix E.) The dataport responds to threetypes of protocol: NMEA-0183, RTCM SC-104, and TSIP.

NMEA Protocol

The NMEA-0183 Standard is produced by the NationalMarine Electronics Association. The SCOUTM+ receiveruses Version 2.0, published January 1991. The NMEA-0183Standard is primarily designed for marine instrumentation tocommunicate using an ASCII sentence library with oneTALKER and one or more LISTENERS. The Standard alsoimplies the use of EIA RS-422 serial protocol with TALKERand LISTENERS in parallel on a twisted pair. NMEA-0183has also been partially adopted by other industries requiring asimple data protocol. It is therefore possible to findNMEA-0183 sentences being used for data transmission ofposition and direction using either RS-422 or RS-232electrical protocols, as well as other more specializedtelemetry links.

RTCM SC-104 Protocol

The RTCM SC-104 protocol is a standard for sending andreceiving differential GPS corrections developed by the RadioTechnical Commission for Maritime-Special Committee 104.Your SCOUTM+ is differential-ready; that is, it utilizesdifferential corrections to calculate Differential GlobalPositioning System (DGPS) positions. For more informationon this subject, please contact Trimble Navigation for a freecopy of Differential GPS Explained, part number 23036.

TSIP - Trimble Standard Interface Protocol

TSIP is a binary hex data protocol that is used with thebi-directional channel in the SCOUTM+. This protocolallows the receiver to interface with other Trimble equipmentand allows development of advanced computer programs forwaypoint and route transfer between a personal computer andthe SCOUTM+.
