Models GPS-100 and GPS 200, Yes. Do not leave batteries in the unit while using the optional power cord.

GPS units operate on UTC time. UTC is the Universal Coordinated Time or Greenwich Mean Time (GMT). Your local time is behind or ahead of Universal time depending on where you are in relation to Greenwich, England. In the U.S., you will subtract the hours difference to arrive at a correct local time reading. You can input a local offset (or difference) from UTC so that the unit will display your local time. This setting can be changed from the Trip page menu - Change Time option. A chart is provided in the owner's manual to help you select the appropriate offset for your area.
GPS receivers do not adjust for daylight savings since the GPS satellite circle the globe and can be received anywhere on earth.

Galileo Specs
You can expect horizontal accuracy of 16' to 45' (5m to 15m) in good reception conditions. For altitude you can expect accuracy +/- 105' (35m)for 12 parallel channel units in good reception conditions. There are a number of environmental conditions that can affect GPS accuracy due to varying satellite signal reception conditions and can therefore lead to better or worse accuracy than listed above.

The external antenna jack provides connection for an active external GPS antenna. Models GPS-100 and GPS-200 requires a straight male MCX connector as a right angled connector may not fit into the unit. WGPX series models require a MMCX external antenna type connection.

The life of the batteries depends on a number of factors. First and foremost is the quality of the batteries you are using. Be sure to select a high quality alkaline or Ni-MH rechargeable batteries. Using the Power Save feature whenever possible and keeping the backlight off when not needed will assure maximum battery life. Switching to simulation mode when satellite reception is not needed (planning routes for example). Depending on how you are using the unit, your average battery life will be between 8 and 14 hours.

High capacity alkaline batteries are recommended. Same capacity recommended for digital cameras and portable CD players. Do not use no name or bargain type batteries. The bargain type batteries will work but will not provide long battery life that the high capacity alkalines and rechargeable Ni-MH offer. Note for GPS-100 and GPS-200 Models: Make sure that the batteries are removed from the unit when using the optional power cord. Damage to the batteries and/or the unit will result.

Ni-Cd batteries can be used but this type of rechargeable battery does not offer long battery life. Cold weather note: Lithium batteries are recommended for use in cold temperatures. Note: DO NOT to mix battery types as this can damage the batteries.

Yes. Note for GPS-100 and GPS-200 models: Since the unit is in simulation mode, it is not actively searching for satellites. When the unit is not active the gauge is not updated. Pressing any button will refresh the battery gauge reading.

Yes. All major interstates, US routes and major cities and roads are programmed into the unit.

Generally, a satellite will be weak if it is very low on the horizon. This means the radio signal has further to travel and is more likely to bounce off of obstructions such as buildings. Satellites less than 5 degrees above the horizon are ignored because they are too unreliable.

Performing the Cold Start function clears the unit's memory of old satellite information. Cold start means that the Galileo has no reference to use as a guide to tell it what satellites should be overhead. Without a reference, the Galileo will have to search the sky trying to find any satellite that may be overhead. This takes time and can increase the time it takes to get its first satellite lock. (Can take 10 minutes in severe conditions.) So where does this reference come from? Under normal operating conditions, the last satellite lock computed before the unit was turned off is stored into memory and will be used as the reference the next time the unit is turned on. Also, if you travel for more than 500 miles with it turned off, it will still have the reference point but it may be too inaccurate to be useful. In this case you may want to perform a cold start.

On models GPS-100 and GPS-200 it means Dilution of Precision(DOP): an indicator of satellite geometry for a unique constellation of satellites used to determine a position. Positions tagged with a higher DOP value generally constitute poorer measurement results than those tagged with lower DOP.
The ideal orientation of four or more satellites is to have one satellite directly overhead and the other three evenly spaced around the receiver. In the diagram at the right, all the satellites are clustered together in one quadrant of the sky. This would result in a poor DOP value. A low DOP value represents a good satellite configuration, whereas a higher value represents a poor satellite configuration. The DOP changes with time as the satellites move along their orbits.

First you must obtain our GPS Accessory Upgrade Pack that allows you to download detailed mapping information and the ability to upload and download waypoints, routes and tracklogs to and from Galileo. This package includes the detailed map, PC interface cable and a Compact Flash card. Next you must find a USB connection on the back or front of your PC and connect the download cable to your PC. Once you have made a connection to your computer then plug in the other end of the download cable to the unit. Now start the Whistler Map program and turn on Galileo. Choose "Loading" from the main menu and select the information you want to download or upload. If you have trouble connecting then check and verify that NMEA output is turned "OFF" on the unit.

You must purchase the GPS Accessory Upgrade Pack which allows you to download detailed mapping information along with more POI's. This package includes the detailed map CD, PC download cable and a Compact Flash card.

Galileo models GPS-100, GPS-200 uses standard type II Compact Flash (CF) Memory Cards. Memory cards come in 16, 32, 64 MB and higher configurations (All Galileo models have a 512mb memory card limit). The addition of a memory card to the unit allows data to be uploaded/downloaded to/from the Whistler Map program. Memory cards can be added to the Galileo GPS receivers through the battery compartment.

If your PC is using an early version of Win98, it may not have the proper drivers to understand signals from the USB port. Upgrade to Win98SE 2nd edition or if your PC is compatible, to XP.
Sorry, Whistler Map does not support Win95 or any Mac OS.

You can refer to the Whistler Map manual. Download a copy of this manual here. Note: You can only save maps to Galileo units with the use of Whistler Map software.

National Marine Electronics Association. A professional organization that defines and maintains the standard serial format used by marine electronic navigation equipment and computer interfaces. Additional information on NMEA can be found at on the internet at www.nmea.org.

This output is used to relay GPS information to NMEA 0183 ready devices. Note: NMEA output will not work in simulation mode. Galileo is not compatible with DGPS devices. NMEA messages are: GGA, GSA, GSV, RMC (standard output)GLL and VTG (optional).

Galileo models GPS100 and GPS200 do not have these capabilities. WGPX Series models do have WAAS capability however.

Initialization can take up to 10 minutes with a clear view of the sky. On WGPX series models, make sure that the antenna is flipped up and "looking" up towards the sky.

The GPS satellites may on rare occasion broadcast a signal error (Selective Availability) that can account for up to 2.5 mph of movement.

GPS elevation will vary up to 150 meters due to Selective Availability. Now that SA has been turned off, (status as of 2005)the accuracy of GPS elevation may vary +/- 15-20 meters (50-65 feet) due to random errors caused by atmospheric delay, incorrect satellite positioning or poor geometry in the satellite constellation.

If you want a record of the track history, leave your GPS turned on. Otherwise, it is not necessary.

No, the GPS satellites are owned by the United States Department of Defense and have been funded by U.S. taxpayer's dollars. Reception of satellites signals is free to anyone.

SA is an intentionally introduced degradation in the accuracy of civilian GPS by the United States Department of Defense. SA errors can degrade the GPS accuracy up to 100 meters. However, this error is adjustable and random. Typically, errors of 30 meters or more are not unusual. Now that SA has been removed, typical GPS position accuracy is approximately 15 meters (50 feet).

GPS works 24 hours a day, anywhere in the world and is not affected by clouds, storms or weather. This is one of the advantages GPS has over Loran C.

A datum is a mathematical model of the Earth. Map makers may use a different model to chart their maps, so position coordinates will differ from one datum to another. Lines of latitude and longitude on a map or chart are referenced to a specific map datum. Every chart has a map datum reference. The datum for the map you are using can be found in the legend of the map. If you are comparing the GPS coordinates to a chart or other reference, the map datum in the Galileo should be selected to the same map datum that is listed as the datum used to generate the chart or other reference. If the datum setting on the Galileo is different than the chart used, your coarse could very well be off. This can be dangerous. The common datum used is WGS84 and this is Galileo's default datum and one of 221 datums in memory.

A waypoint is a marker, shown on the map, to a location you would like to come back to another time. This waypoint could be a POI, intersection or a favorite fishing spot for example. Up to 500 waypoints can be stored in Galileo model GPS-100 and GPS-200.

For models GPS-100 and GPS-200, make sure that the waypoint icon is turned on. To check, press the Menu button and select "Display Icons". Make sure that there is a check mark next to the waypoint icon.

A route is a series of waypoints entered in the order that you want to navigate them.

Think of track logs as simply "bread crumbs". Leaving a trail behind so that you can find your way back. The track log is shown on the Map page by dots along your route. TIP! To help make the "bread crumbs" more visible, you can turn off the type of road you are on in the "Display Icon"menu item or simply turn off all roads by pressing and holding the zoom out button.

On models GPS-100 and GPS-200, NO. You need to make all your map selections at one time. Adding additional maps to the memory card will cause the GPS unit to ignore one or more of the maps placed on the card.

On models GPS-100 and GPS-200 when a set location is choosen simply pressing the "OK" button returns the map to the current position.
