CSC - GPS accuracy connection (??) - Samsung Galaxy Watch

Hello!
My Galaxy Watch showed perfect GPS-accuracy when using Smart Caddy for measuring distances in Golf (compared with a Garmin watch and the markings on the course, +/- 1 meter).
Since I changed my CSC from ATO (on firmware DSL1) to XAR I have big deviations from up to 30 meters in GPS measurement (when I get closer to the hole the accuracy inreases).
Can there be any connection between CSC and GPS-accuracy?? I found this issue with firmare CSE1, CSI1, DSL1 and DTC1.
Any ideas??
Thanks!

Nobody an idea regarding this topic?

Fantastic Holux GPSlim236
I made the jump to a new GPS mouse, as I was tired of waiting up to 10 mins for acquiring a signal.

Hi LinuxGeek,
I recently bought a 'inter-active information' BT GPS off eBay and it works a treat with both my M5000 and Symbian 60 mobile. In reality all GPS are much the same. You only need a 12 channel receiver for SatNav etc as only 3 sats are needed for 2D nav and 4 sats for 3D nav but 8 sats will give you a good accurate fix so don't be tempted to get a 32 channel receiver. I've been recommended to get a GPS receiver with RFMD or SRIF III chipsets due to the cold & warm aquisition times.
Hope this helps...
Gavin.
That is incorrect. They are not 'all the same' although most SSIII receivers offer sim ilar excellent performance.
If at all possible, choose a SirFStarIII (SSIII) receiver.
I have a very commun GPS named, socket BT GPS, I bougth in Expansys (Spain) almost a year ago. The price, 113,00 €. It is the first global standard for short-range wireless communication. Bluetooth also provides low power, standardized connections between a wide range of consumer, enterprise, and industrial devices. The Socket GPS receiver will track up to 16 satellites and provide position accuracy down to 2.5 meters and with the removable, rechargeable battery provides up to 9 hours of continuous use.

The best is Garmin GPS10. Very tiny, magnetic support inside and woks fabulous, till 5 meters in deep water and is the only one that works inside a airplane, because measures velocity till 1280 Km/h. The others when the plane reachs 400-500 Km/h stop sync....It´s not cheap, but is the best...

Ehhh......where on earth do you get the deep water info from? Garmin states: "submersible in one meter of water for up to 30 mins". They also mention "Waterproof — so it can be mounted outside the car for a clear view of the sky". I find the Holux quite amazing, it even keeps a signal captured when I put it in the stowaway area located behind the handbrake, in-between the two front seats! No outside mounting required here ;-)

Yes, they all work in aeroplanes....near a window...till 400-500 km/h... But at 900-100Km/h in a comercial airplane how many work? Have you tried? or is just theory? I´ve tried MANY "cheap" gps receivers (ex. Holux 230...) and work till 400-500Km/ my friend... Read the complete specifications and give a try...it´s the best way to achieve acknolege...
It's the same underwater. I use My garmin GPS10 till 25 meters in deep water without capsule... I´ve logs from my underwater computer...So, give it a try

Yes I have tried! All consumer GPS are limited to 1000Kts and 60,000ft altitude. I don't know of any commercial aircraft that fly above those limits!

I also find that claim impossible to believe. The high frequency signals will not propagate through a few mm's of water let alone 25m! Are you using a surface antenna?
fslunatic:
I bought the same GPS device, but my Exec is not able to identify it.
I would appreciate it if you could you tell me if you made any changes to the registry and which COM port are you using (in fact it would be execellent if you could list all of the setup details); Or could you please reffer me to the relevant forum pages.
Thanks

Did you read the posts before yours?
You have the full specs for hollux gpslim 236 where it states clearly 700 knots do you know how many 700 knots is? You're right it's 1300 km/h
Hi techDot,
I didn't do anything unusual really. I switched on the GPS device and then activated Bluetooth on my MDA-Pro. I then let the MDA-Proi look for Bluetooth devices. It found the GPS and then I set up a standard partnership....it took less than 2 mins.
I believe I am using COM0. What navigation software are you using? What particular steps are you going through?
I didn't touch the registry or anything....all very straight forward. Hope we can help you and get it working.

LOL! Hehe......
Assuming i were to by the one suggested by fslunatic, what would be the best navigation software? i don't know a great deal about this subject. I have been looking at the tomtom software but, a) can't find somewhere that just sells the software / maps and b) find anywhere that says it is compatible with the HTC universal (XDA Exec in my case) windows mobile 5 software.
Anyone shed any light?
P.S. How much did you pay for yours fslunatic?
I use an O2 Exec with TomTom 5 and it works superbly.
Excellent did you manage to just by the software from somewhere or did you buy the 'tomtom kit' they mention on the website that includes the GPS unit and all? i'd rather by the GPS unit mentioned by fslunatic and buy tomtom software separately, assuming it's all compatible of course (anyone know?).
gratz: Try looking here: http://www.tomtom.com/products/product.php?ID=109&Language=1
EDIT: Doh! They don't sell it on their website! Try here: http://www.pdamods.com/proddetail.asp?prod=X1TTSOFT for UK on an SD card or here: http://www.pdamods.com/proddetail.asp?prod=X2TTSOFT for the rest of Europe.
£120, just for the software? That's ridiculous :shock:

Do you guys all have your own planes? It's just that I've never had the need for Sat Nav on a commercial plane before. I find they rarely take a wrong turn ("At the next fluffy cloud, turn left") and no matter how many times I enter my post code they always take me to a flippin airport! :wink: :lol:
On a serious note, is there a plug and play packege that needs no clever programming or other jiggery-pokery to get working?

GPS psoition not exactly 25 to 50m difference

Hello,
my gps has no right position i think the difference is between 25 to 50 m
Is there a tool to correct this issue ?
Thx
Nochmal in deutsch falls mein Englisch nicht so gut zu verstehen ist
Mein GPS im Artemis hinkt etwa 25 bis 50 m hinterher was sehr nervig ist
Kennt jemand dieses Problem und weiß wie man Abhilfe schafft ?
From what I recall no civilian GPS is precisely correct.
Only Military GPS is precise to the metre.
Not sure what the exact varience is though.
Regards
i have navigation systems before the p3300 and on all when the street cross comes it brings exactly the position when it says turn left at 50m then it was correct, i believe the military difference is only 1m or lower not 50m ???
For external PC gps receiver there is a software for correct some options for the inbuild gps.
I have no glue for a in built gps.
Sorry for the English this not my normal language, i hope you can understand what i mean thanks
Also, better accuracy depends on the number of satellite signals the device can get. Signal strength is weaker in the urban areas.
What software application are you using when you notice the discrepancy? I have found my Artemis GPS position to be equal to some of my other units. For example using a topographical map when out walking the unit is very good, certainly not 25 to 50 M out. It could be low signal strength and reflections off other building that is causing a problem (if in built up area)
One other consideration, how many other applications do you have running at the same time as your Nav software, your device might be struggling under load, check settings/ system tab Memory icon/ running programs and stop all before trying the nav software Mike
My device, which is still the Magician is running the ROM 1.13 with BS. Additional software which are all installed in the Storage are; Pocket Informant, Photo Contacts Pro, Resco Suit, SK Tools, TT6, WorldMate Pro, Ring tones. All TT maps (WEU, USA+Canada), voices, schemes, zip codes, POIs and IE Temporaty files are installed in a 2GB SD. What's left in available memory are Storage = 0.7 of 26.72 MB, Storage Card = 105 MB of 1935GB.
The programs that are running (being memory resident) while TT6 is active are Photo Contacts Pro and Pocket Informant. I have BT on all the time since I use a BT headset for calls while driving. TT audio is via my Seidio active car holder.
The programm ist TT6 and only jetware, and ilauncher active nothing more, the area is no big city good sight to the air.
I checkt this with tt5 and a hp2210 with bluetooth sirfIII this combination is near perfect
I've never used those programs. The inaccuracy might come from any of the two.
Civilian GPS is officially (from the provider of the GPS System - US Forces) something about 10 metres unexact. Of course this number can be smaller if you have more satelites "in sight" However, GPS Navigation Programs do not need accurate positions, they calculate the position on the map with old data and then extrapolate it, showing the dot where you should be now, according to your speed and heading 1 second or two seconds ago. Of course it can control its calculation because more data streams in. It is funny to see Navigationsoftware Confused, when you ride a train. It gets a signal in a certain direction, with a certain speed, so it puts the dot on the street next to the Rails, because this is the only logical position where your car can be so it says "turn left now" but the train goes straight. Then it searches another street you could be on. just funny
But in short: GPS Software compensates missing GPS accuracy, mostly well, sometimes not so good. Try using another Software or newer map ,maybe that will fix the problem. On my MDA Compact III The Built in Receiver works just great together with TT6. Maybe there is a way to shorten the interval between two data sets. That would give the Software more information, resulting in a more accurate position. But i don't know if a program like GPS Maus can manipulate Built-In receivers that easy.
I once reprogrammed a T-Mobile Receiver with this program, so it received also NMEA data and the intervall between two data sets could be set randomly.
In the UK, the BBC send out a spoiling signal which reduces the accuracy of the GPS. It is also sent out from National stations in other Countries. I heard it was sent out with the atomic clock signal. This is to stop "undesirables" buying civilian GPS units and fitting them to military equipment and sending something directly to your letterbox - the same way a US military GPS unit can if they want to! You used to be able to buy a box that would correct the error signal, but that got stopped ages ago.
The GPS also becomes slightly more inaccurate depending on the speed you are travelling, travel under 30 mph / 50 kph and the "you have arrived" will be within a few yards/metres of the real arrival point. Travel at 70 mph / 120 kph and the "take the exit in 200 metres" is very inaccurate - maybe by a couple of hundred metres - you can work out why!
Also GPS signals are "secondary" and can be turned off at any time in the event of a military requirement - which is why you can use the signals free of charge.

Are you confusing the selective availability that was used to degrade the GPS accuracy up to a few years ago? - The US reserve the right to switch it back on again should they need to, but under normal conditions the signal is not de-graded any longer. If you want to send something to a letterbox the Post Office offer quite a good service

The issue of position inaccuracy relative to speed won't give a major difference to position - the software maybe responsible for the apparent degradation though.

Static Navigation in Artemis
In Artemis is a Sirf-III-Chipset. One of the "features" of this chipset is a Parameter called "Static navigation".
This gives a more or less "static" position if the device is moving rather slow, like a pedestrian does.
Useful for car navigation because your car is not "dancing in front of the traffic light".
But it gives a more or less not accurate position when standing or moving rather slow. You need to move with 5 Km/h at least.
No tool for switching off "Static Navigation" in Artemis seems to be working.
BBC jamming the gps signal..?
Selective Availability:
"SA works, for the most part, by intentionally dithering the clocks in the 24 satellites that make up the GPS system. The clocks are steered by an algorithm, known to the control station and military receivers and transmitted in encrypted code over the satellite signals."
http://www.exn.ca/FlightDeck/News/story.cfm?ID=20000502-53
The BBC does what??? I don't believe that for a moment!
The GPS signal I get on my Orbit and previously on my Fortuna Clipon has been extremely accurate, using different software Tomtom 5 & 6, pocket streets and Vito all have been down to a couple of meters at most.
I have also used in the US, Cyprus and Spain all with the same accurate results.
Yes the US can turn off civilian GPS if they wish, which is why the EU is building Galileo.
duh... SA has been switch off 7 years ago!
interesting to see people still talking about SA, it has been switch off since year 2000!

GPS working but very wrong position

Hello, for about 2 weeks my gps has been working and has been taking a little bit longer than normal to lock. but thats not the problem.
the problem is when it does lock the position will be off by 1/4th mi to about 3 miles and its usually connected to 8 or 9 sats and says position within 10-20 meters
im not very good with the metric system but im pretty sure that 20 meters does not equal 3 miles and the little blue circle is not that big
and keep in mind this is outside clear weather and no big buildings around
i was wondering because i heard that there will be no more funding for the gps sats and would slowly start failing because they wont get the upgrades they need and also i heard about a month ago that there will be some big solar flares that could mess up the sats
another thing is using gps test. is showing that the sats that are connected are lower signal than they usually are. mostly in the yellow. but i see no reason for that...
this only started happening for about a week or 2.
anyone else having this problem? can a radio update fix this? if so which would be the best one for t mobile usa (link if you can)
Radio ver: 4.49.25.57
thanks for your support,
Darian
turn off your agps, as it uses cell tower signals to locate you, and can over ride the gps signal you are getting. the agps is triangulating your position and is generally only accurate to 300 to 1300 meters.
i thought agps was only used to get a faster lock on the sats

GTab 3: poor GPS performance? How to improve it?

Hi people,
I have recently bought a Galaxy Tab 3 7.0, brazilian version T211M with 3G and digital TV.
The idea was to use it as an in-car multimedia and GPS device using Waze. I made some tests using my Nexus 7 2013 for this purpose, and it worked flawlessly. So I bought the GTab 3 to be a dedicated tablet for this.
The thing is: the GTab 3 GPS is nowhere near the Nexus 7 GPS performance. My N7 is able to find three or more GPS satellites and lock position in a couple minutes inside my car's garage (which, BTW, is not underground, it's the building's third floor). And without A-GPS (it doesn't have 3G connection, it's the wifi version). In the same situation, the GTab 3 keeps looking, looking... and nothing. Yesterday I went out driving, and it took 15 minutes for the GTab 3 to finally lock GPS position.
Another funny thing that happens is when I stop, for example, in a traffic signal. The GTab 3 GPS gets confused somehow, it's not sure if I'm moving or if I'm stopped. Its speedometer marks 0 km/h, then 2 km/h, sometimes even 10 km/h, then 0 km/h again, the speed keeps going a little bit up, then down. Again, different from my N7, which was very precise.
As a last test, I put both tablets in my place (I live on the 9th floor), over my sofa, right beside a window and a door to the balcony. Using GPS Status (you can get it from Google Play), I tried to find GPS satellites and lock position. The N7 could do it in a couple minutes. The GTab 3 couldn't do it. I had to go outside to the balcony, stood in its end, and then finally the GTab 3 got a GPS lock. But when I go back inside, it loses the GPS signal.
I'm very disappointed about GTab 3 GPS performance, it really ruined my car tablet experience. But before I sell it and lose some money, I have to ask: is there a way to improve it's GPS performance, so that those issues are gone? Or that's the way it is, and I can't do anything about it?
I recently bought one too, haven't tested the gps yet, but comparing with my Note 3 with AGPS, it´s surely much worse.
This post talks about a gps bug?: http://www.gpspassion.com/forumsen/topic.asp?TOPIC_ID=138317

Distance measurement is wrong

I run a distance that is approximately 800m and i do like 5 rounds, so overall i run 4 km. The thing is that the band shows that i have ran only 2.5km. Why is that? Is calibration wrong?
I choose the outdoor running function.
Mi Fit/Mi Band uses standard step lengths - based on your height, weight and maybe even age. If your step length is too much below/above average, it could impact the distance calculation. To have accurate distance, you have probably only two options:
1. use phone GPS to track the distance - but you must have the phone on you during running.
2. use app like Notify & Fitness and adjust your step length to your real value
I have exactly the same problem as described.
The interesting fact is that the difference between real and shown distance is always 1,6. And that equals the conversion factor from miles to km.
So the 2,5 km are actually 2,5 miles which equals 4 km.
Changing the units in the app didn't make any difference for me. So I think it's "just" a software bug.
If you change units in the app, do you see a change in Mi Fit and status menu on the band? For me it changes correctly between km and miles. Also the distance in Mi Fit and Notify & Fitness is roughly the same 4.29km vs 4.49km (N&F uses own step length to calculate the distance), so the information should to be real.
For "stuck" Mi Band it's usually recommended to perform band reboot and if it doesn't help, then re-pairing in Mi Fit. Have you tried it?
apologies for bringing this one up from the grave, but did you manage to fix the problem?
I have the mi band 5 and the same problem. It shows 6.1 km but the distance (I measured it with google maps) is about 9 km in real. What is wrong?
I am having the same problem with Miband 4. I use turn on the function walking when trekking in the mountain and when making 16 000 steps, the app shows that I have walked 15.8km which is completely impossible. GPS on the phone is turned on.
I have they same problem, Mu band is 4000 steps and realy are 2500
Enviado desde mi LM-G710 mediante Tapatalk
I'm facing a similar issue in mi band 6 after the latest software update. It tracks 9kms when I actually do 10kms.
