Question about Lowrance Lms 520c 5" Screen Color External Gps And 200 Khz Sonar System

3 Answers

Lake map is locked up-same position as turned off on prior trip.

No apparent GPS signal on screen since last trip out 2 weeks ago. GPS seems always slow to pick up and often loses signal but does retain signal or position eventually, until now(last trip out). Help

Hi TBS,

When you power up a GPS, it assumes it's still at the same position it was when powered down. If that position has changed, it will normally take at least three sat-locks to triangulate the new location and begin registering motion vectors.

Unit location and/or Antennae location are major factors in signal acquisition speed. When I plan on using my portable unit, I'll power it up outside the car. I get acquisition in half the time. Once it locks on, no problems. I just get impatient..

From what you have described, it sounds like normal (if not slower than normal) operation. If there are other symptoms, please reply with details.

Thanks for using Fixya

This is completely normal, particularly if the phone's environment restricts satellite visibility or signal quality in any way. It takes time to lock the satellites and assess the quality of signal.

Great weather conditions start flight in GPS mode few 3-5 minutes into flight the RTL failsafe turns on


Updating firmware is always a good start. My question would be, is it losing satellite contact due to positioning or surrounding materials blocking the signals from one of the 33 satellites that make GPS work.

Since a few weeks ago, when turned on, "GARMIN"


GPS SYSTEMS HAVE A TENDENCY TO LOSE CONNECTIVITY TO SATILLITES BECAUSE OF BAD WEATHER, CLOUD COVER, TUNNEL ENTRANCE, BAD OR NO POWER, BATTERY LIFE HAS BEEN EXPENDED, HAZARD OF ELECTROMAGNETIC INTERFERENCE TO GPS SYSTEMS, AND IMPROPER VEHICLE MOUNTING AND HAND HELD POSITION. FREE SOLUTIONS 1. ALWAYS PLACE YOUR GPS DEVICE IN THE UPPERMOST PORTION OF YOUR VEHICLE SO THAT THE GPS SIGNAL MAY EASILY LOCATE YOUR DEVICE EVEN WHEN THE WEATHER IS BAD 2. KEEP YOUR BATTERY CHARGED ONLY WHEN IT NEEDS IT MOST AND AVOID CHARGING OFTEN 3. IF YOU OVERCHARGE YOUR GPS DEVICE, YOU WILL EXPERIENCE BATTERY LEAKAGE, WHICH CAN EAT AWAY AT YOUR CLOTHING, DESTROY YOUR DEVICE IN SECONDS, AND CAUSE DAMAGE TO YOUR VEHICLE SEATS 4. YOUR GPS DEVICE HAS A TENDENCY TO FREEZE BECAUSE OF THE SIM AND MEMORY CHIPS LOCATED WITHIN IT 5. YOU CAN FIX THE FREEZING PROBLEM BY REMOVING THE SIM CHIP AND MEMORY CHIP AND RESTARTING YOUR SYSTEM 6. OTHER FREEZE PROBLEMS OCCUR BECAUSE THE DEVICE IS COLD WHEN IT IS KEPT IN THE VEHICLE AND CHIP CREEK OCCURS WHERE THE DEVICES MICROCHIPS BECOME LOOSE AND TIGHTEND BECAUSE OF WARM AND COLDER AIR FLUCTUATIONS. IT IS BEST TO KEEP THE DEVICE IN A PURSE OR ON A TABLE WHERE IT IS NOT SUBJECT TO CONSTANT TEMP. CHANGE 7. PREVENTION OF ELECTROMAGNETIC INTERFERENCE IS BEST SOLVED BY: interference from devices located nearby, and even a radio turned on and located really close to your unit. This is normally known as electromagnetic interference to electronics and is very common

Garmin nuvi 760 loses the road that I am on for no apparent reason. Car icon is visible but no road image. I am not going off-road. The road graphic will be displayed but during the trip it will just...


Are your maps updated?

If so the road you on a new road that hasn't been programed into the maps yet?

Could be a few things going on, lost satelite, or a new road.... word to the wise Always carry a road map in your vehicle, GPS is a great tool but not always 100% right especialy if your on a new road, Maps are updated I believe every 6 months or more.

Love my 760

I want to use the gps and navigator on my nokia 5800 can you please help


The Nokia 5800 has a built-in GPS satellite navigation receiver, which can tell you where you are anywhere on the planet. The 5800 also has cell-tower-positioning technology, which finds your location using the position of the nearest phone network mast if a satellite signal is unavailable. GPS is more accurate but can take a while (from 10 seconds to a few minutes, depending on how obstructed the sky is) to find your position ('Assisted GPS' is also present, to download the expected GPS satellite positions from the Internet and help speed up your fix.)
The 5800 also has a built-in mapping application called Nokia Maps, which shows you your location on a street map, tells you exactly how to get to another location by driving or walking, and can give details of nearby amenities such as shops, fuel stations, museums, etc. Nokia Maps uses both GPS and cell tower positioning to tell you where you are: the latter gives an instant rough position, while GPS data is used after the phone has locked onto enough satellite signals calculate its position. You'll know the phone is locked onto a satelite as the lock indicator at the bottom of the screen will turn green.

Other phone applications can also use the GPS receiver if required. For example the camera application can optionally "geotag" photos with your current location using the GPS receiver to work out where you are (click here to see our camera tutorial and find out more about geotagging). If you switch to the standby or menu screens while an application is using the GPS receiver, you'll see a little satellite icon in the top right corner of the screen to indicate that GPS is active.

How does the 5800's GPS work? Like all satellite navigation systems, the 5800 receives signals from many different GPS satellites in the sky, and calculates your position based on those signals, using a combination of triangulation, signal delay calculation and a lot of very heavy maths that you really don't want to know about.

Important Note: Satellite signals cannot penetrate buildings, so GPS satellite signals will be difficult or impossible to receive if you are indoors and away from windows. If you want to speed up the process of GPS showing your location, take the phone outside or place the phone next to a large window with a good view of the sky.

The 5800's GPS aerial is inside the top left side of the phone. If you want to get a good GPS lock make sure this part of the phone is uncovered

Tom Tom XL shows me 200-300 yards from my actual


1- Signal strenght loss is a common problem, has to do with how often they refresh, whats on your dash and how good the line of sight is to the gps sattelites. Ironically the window mount that they give you can in some cases place the gps unit too far back from the window to get good clear reception.
2- You are out in the field because of the maps that you are using. Maps while mostly accurate are not exact and road changes that are made to sections of road may take years to show up in the map or might never show up. There are only two or three actual companies that do the gps survey work for the roads, and gps manufacturers like Tom Tom buy user rights to use these maps, so if a particular section of road has changed or been moved and nobody has been out to recalcute the changes then your gps will be off the mark.
Hope this information helps you out.

MapCreate Topo does not have lake maps. There are 'some' maps on Lowrance's web site (Free Enhanced Lake Maps) but you may need to purchase lake maps on SD cards for the area you're interested in.

Garmin summit hc seems to be off by more than 300 feet


First of all make sure your etrex is not set up to follow roads (if it has that facility). Maps are not always accurate particularly edges of lakes and forest boundaries. If your etrex can only see a few satellites then accuracy will be degraded. Make sure your body is not shielding the view of the satellites by holding the unit away from you. The accuracy of any GPS is affected by the relative position of the satellites with respect to each other. If they appear (at your location) to be in a straight line then your GPS cannot perform the trigonometrical calculations to determine your position with any accuracy. In GPS speak this is called DOP - Dilution Of Precision and can result in variable accuracy from +/-5m at best to +/-30m or worse.

Topo maps a mess of meaningless lines


Sorry for late reply. You need to select an area on your topo map prior to downloading it. For example, if you plan to go to Algonquin Bice Lake (access point 4), then you need to select the map around the area (starting from) Kearney upto the Magnetawan Lake and beyond. Mark waypoints from the put-in to the campsite on Bice Lake (best to compare of the topo and Algonquin canoeing map). Then you can click Transfer, click Send to Device (GPS 76cs should appear) to download it. On the GPS, enter the Find Waypoint button and you should be able to see those waypoints. Good luck for your next trip.

No GPS Signal in TomTom One XL all of a sudden


I suddenly lost the GPS signal today and could not get it back. All I got was the "No valid GPS signal". My solution was to tap on the GPS satellite bars when in the route map. this brought up the "Status summary page of the TOMTOM.

I then again tapped the satellite bar which brought up the "GPS Status" page. I then tapped the bar labeled "configure".

The radio button next to the option titled "Minutes (dm.m') was selected. I then moved the selection to "Degrees (d.d) and it started working.

I had just downloaded the GPS fix 5 days ago so it is not like this suddenly caused it to stop working.

This may not work for everyone but this is what it took to get mine working.

Cheers

Coordintates seem to ALWAYS be off by 20-50 feet


How are you determining your error? If you are comparing your position to a map and you are getting error consistently, it could be that your map datum does not match the datum set in the GPS. Without WAAS turned on, your error should be @15'. With WAAS on it should be @ 6 to 9'. If you are using the Sattelite screen to determine your error, remember that is just estimated error. Higher estimated errors can be caused by satellites that are blocked or not visible to the GPS, or poor satellite geometry. It is normal for example, to have more error in high northern or southern latitudes due to less satellites being visible. With good reception you should be able to see 8 to 12 satellites on your satellite page. Signal strength is also important, You can have a lot of visible satellites but if the signal is weak your error wil increase. The signal can be weakened by heavy tree cover or high objects such as buildings or mountains. Such interference is called signal path error. Another form of signal path error is when the signal gets reflected off something before it gets to your GPS. For example; you're in a canyon and satellite 1 is to the east of you. The eastern rim of the canyon blocks the signal from satellite 1, however the signal bounces off the western rim and your GPS then picks it up. Because it took longer to get to your GPS, the GPS thinks that the satellite is farther away than it really is, causing a postion error. (This would not show up on your estimated position error shown on the satellite page because the GPS does not know this is happening.)

When WAAS is turned on it takes a channel that would normally be dedicated to a GPS satellite. It's possible that turning off WAAS helped you because having an extra GPS satellite improved your geometry which improved your accuracy more than the corrections WAAS is designed to make. The next time your error seems high, check how many satellites are being tracked and how strong the signal is.
