GPS Comparison : Kaiser Qualcomm vs Mio SiRFstarIII - Tilt, TyTN II, MDA Vario III General

There have been recurring questions on how the Qualcomm GPS intergrated chip compares to a SiRFstarIII chip on a PDAPhone like the Mio A501/A701, so I spent a lot of time comparing them in this article http://www.gpspassion.com/fr/articles.asp?id=237

3. Signal/Conclusion : http://www.gpspassion.com/fr/articles.asp?id=237&page=6
Bottom line is that the Kaiser does fine for car use , less so on foot. In any case a huge improvement over the Trinity !

How about comparing Kaiser against P3300, and then also against new chipsets that are even better than Sirf III ?

I appreciate the work done, Thanks! It confirms what I see in use, it's a very decent GPS mapper in the car. I use it all the time and it's very reliable and very stable and sensivity compares to all my previous standalone BT receivers. I'me sure there's better, but this is perfectly good enough.

Anyone with GPS Holux BT 236 sirf III

Hi,
I am thinking to bye a GPS, an my decission is between GLOBALSAT BT-338 Sirf III or HOLUX BT-236 Sirf III. It seems that Holux detects EGNOS.
Sorry for my English.
Did anyone have experience in QTEK 2020i and Holux?
Thanks
Hi,
I have a Holux GPSlim236 working with my Qtek2020i and it does the work. It installed simply on the Qtek and worked well with TTN5.
However, i wonder if i really needed to spend the extra bucks for a Sirf III chipset GPS, as i see no difference in performance between this 20 channel device and other less expensive (with fewer channels) devices.
I Think a 12 channel GPS is good enough for most of the applications (at least for use with TTN5).
This device has something i like (i've seen it on other brands too), which is the battery that is compatible with some Nokia Phones (like the 6600), so you can use the phone's battery if the GPS runs out of battery or use the GPS batery as a replacement battery for your mobile phone ... neat
I have no experience on the globalsat.
My advice is --> Buy the less expensive one!!!

TYTN II, worth to buy?

Hello everybody,
I have a question, maybe somebody can help me here?
I am using an Artemis and consider to buy a TYTN2. Is it worth to change? I know, this is a strange question but maybe somebody had a Artemis before and is now using a TYTN2.
I guess iGO will work on the TYTN2 as well, is somebody using this SW?
Thanx in advance,
Ralf
If you look at GPS, yes, unnlike the P3600 Trinity, you are ok with the Tytn II GPS: it has a working quick GPS program. According to GPSPassion.com, the GPS quality is significantly improved, equivalent to the SirfIII (which you have in Artemis). The unit is slightly fatter and heavier though. You also have no FM radio. I like the one-hand navigation possible through the jog wheel on the side and the ok button on the side, which opens the windows menu when pressed. The tilt is nice when you keep the unit on your office linked to the PC, because it's not lying flat on the desk, you can see on it very well. Also when you use it as an alarm clock near your bed. Last but not least: WM6 without overclocking...
funny that you visit a Kaiser/TyTN II forum and ask that question
iGO do work on the device ... it's basically the OS that you should referred to when dealing with SW
I use it without any problem ... infact, I preferred it over TomTom !!!
yes i know, sorry for that
i think i will go for the tytn2, i was just looking for opinions and for the confirmation that iGO is working without problems. i need iGO for eastern europe, tomtom is here not very strong in map availability
thanx to all
ralf
If the weight is not an issue for you
If you can survive to the lack of VGA screen for surfing...
Then go and buy one
It's all great !

Differences between Kaiser and Hermes

Apart from 128/256mb RAM/ROM, 3d accelerator, GPS, and 3 px camera... what it is included in Kaiser that differs from Hermes?
I'm planning on buying a N95 8gb or switching my Hermes to a Kaiser... but things that mainly are most important to me (HSDPA and WM6) are already included.
Anything else to comment?
Regards.
From a hardware prosepective, its completely different components in a similar case. The Kaiser uses a different processor (of the same speed). The Kaiser has different radios (although they do the same things as the Hermes Radio, bluetooth, wifi, 3G/GSM). The Kaiser has USB2.0 instead of 1.1. The Kaiser has a scroll wheel. Of course the Kaiser also has a screen tilting mechanism, which is quite handy.

How to make it beep-beep

Hi.
I've used 4-5 GPS apps and I couldn't find option to set a sound (in my case beeping sound) when I gain vertical speed. I wanna use my tilt like a paragliding variometer cause i can't look at the phone and enjoy the view .
So is there app that have that option or could you make one plz.
You can search on youtube to see how variometer works.
A paragliding variometer can have up to three ways of letting you know your vertical speed. Audio sound, digital readout or analog clockface. Some varios are quite basic, like the simple audio-only vario with nothing but an Off/On switch.
Let's have a quick look at each type in turn.
The audio sound indication. If you are going up faster than a pre-set value, you hear a beep-beep tone which increases in pitch the stronger the lift is. Different models have different sounds. Some of them have a sink-alarm as well, warning you with another sound that you are sinking faster than some pre-set value.

The TyTN II is missing the hardware required

Firstly welcome to XDA-DEV arminf! I know exactly what you're after but the HTC TyTN II (and consequently also the Tilt) isn't equipped with enough hardware to be able to do that. There's no Barometric capsule to sense changes in air pressure and no accelerometer so it's no can do using just the phone. Interestingly the Tomtom Navigator version that came with my TyTN II has a setting for which units pressure is to be displayed in (but it has no way of getting that info). Maybe with future products if you let HTC know you'd like this capability included, they may listen (oh, and don't forget to ask for complete driver support while you're at it ). The Touch Pro has an accelerometer but I don't know if it's capable of sensing acceleration in the right plane and whether it can be harnessed using software for this specific purpose.
Surely it should be doable. GPS gives your 3d position, so all software has to do is give compare the positions and times of two subsequent positions to work out the vertical speed.
It should be quite simple for someone who actually has a clue how to program for Windows Mobile

Wow you are really into variometers , and i know that Tilt doesn't have Barometric capsule, but I was trying to improvise with GPS. So i just need that beeping sound on some GPS app when I'm going up

Keep in ming though that the GPS inside the TILT uses a perfect sphere model for the planet (AFAIR). So it is possible that you will get a number of false posities/negatives on an extremely uneven terrain...
But yes, in principle it should work.
TyTN II hardware still not up to the task
Whats needed for the intended purpose is something that reacts instantaneously (or very close to it) and with imense accuracy to sense when it's rising or decending and at what rate. If the device is to slow or not accurate enough (and I believe relying solely on the TyTN IIs GPS would present these issues) then you'd end up flying right through the thermal and out the other side or through the ridge lift and into the rotor etc.
When I first bought my bicycle and was looking for a GPS device to go on it (before I bought my TyTN II) I was looking at Garmin pocket GPS units one of which had an aneroid capsule built in. I checked their website and this model is still being sold and this is what it says "For extra-precise climb and descent data, Edge 305 also incorporates a barometric altimeter to pinpoint changes in elevation." Having used the TyTN II's GPS with TomTom Navigator, Google Maps and Microsoft Live Mapping, and seen how it sometimes struggles with basic 2 D mapping, I definitely wouldn't trust it to be up to speed in what the OP wants - irrespective of what software is coupled up to it.

TMC-receiver (BT) for HD2?

Hi,
Does anybody know about a working bluetooth TMC-receiver for Leo? I need only TMC but I'm not really sure what I should buy. Maybe anybody of you has a working one - please tell me which one.
Big THX in advance!

HI, it´s possible to use the inside radio to recive tmc signal. But only with the cableheadset.
Is it already possible also with HD2? Last time I tried (3 days ago) hyperGPS was not suitable for HD2.
No, it is not yet possible to do so... I am waiting for this too...
De Wolfe: check gns-gmbh.com/index.php?id=80
GNS TrafficBox Plus FM9BT-C or its identical clone Navilock NL-324BTR (comes a little cheaper). Tested with HD2 + Navigon 7.3.6 and 7.4.0 PDA.
No HyperGPS/proprietary TMC yet.
I've tried Hypergps with my HD2 with no success
The starnge think is that Igo8 discovered TMC when Hypergps was set to port com 7 and GNS protocol. Unfortunately there was no way for me to set the correct FM frequency for RDS
TMC working with external BT GPS/TMC receivers
I got my new HTC HD2 a week ago. Igo8 runs exceptionally fast. I wanted to still use TMC data as well as I have paid for it (naviextras) and am used to it on my Pocket PC's (ipaq 3970, 5450, 5550 and 4700). I tried the HyperGPS route with the headset lead (you definitely need to plug a lead in to act as FM aerial). The only way I get TMC information working is to use either the GNS BT GPS/TMC receiver (GNS5843) or the Royaltek (RTG1001). I can either use internal GPS of HD2 (port 4 baud rate 57600) and get TMC from the BT GPS on port 2 at baud rate 57600. Port 2 seems to be the only option you get when you add (pair) the BT GPS devices and pick an external GPS port. I intend to generally use the internal GPS, but when in the car and going some distance or in bad weather if necessary will switch on the GNS 5843 go to igo8 setting/TMC pick GNS (protocol) port 2 and baud rate of 57600 (even though the manual says 38400). I get the message TMC Hardware detected and off It goes searching for RDS signals of the FM transmissions and extracts the TMC codes to integrate with your map and route. I have my GPS/TMC device semi permanently in the car (using velcro pads) by the windscreen or sun roof to get a better view of the sky for the satellites and the aerial suckered to the top of the windscreen so as not to have the FM signal blocked by the metal of the car's metal frame. Be aware that if you have a car with the 'athermic' windscreens that this will weaken all radio signals to your device (satellite, mobile & FM/RDS).
I better mention that I am in Northamptonshire in England in UK. You need to be in area that is covered by TMC carrying radio stations (non BBC), example are Classic FM and leicester sound, Heart FM, etc. etc..
Dear Mr de Wolfe
I use the "GNS TrafficBox FM9BT-C - Bluetooth TMC / TMCPro Empfänger mit KFZ zu USB Adapter" wich is a bloetooth tmc-module built in a car-charger.
It works pretty good, signal is ok with the short antenna and is very good with the cable-antenna. The charger is strong enough for the HD2 (wich is mentioned as problem in the comments of the website)
I got it from here: "http://www.pdamax.de/?art_nr=gn-003"

I can confirm the gns 5843 working. but i do have, after activating bluetooth, to connect the com2 manually. only activating bluetooth does not do the trick. the gns unit is paired but com2 does not connect. so igo does not find the tmc signal.
after manually connecting com 2 it works like a charm.
little annoyance and would like to find solution for it. if anyone knows.
example of sys.txt tmc setting for HTC HD2
I think you can get around this by adding some text to the sys.txt file under title of TMC and you state com port. Port 2 in our case.
[tmc]
port="" - comma separated port name and port number pairs for ex. "COM,1,COM,2,COM,3"
source="" - if it is not specified then the program tries to autodetect or the possible strings are
gns
royaltek
amaryllo
samsung
opentmc1
opentmc2
ngalik
eten
harman
gps_source= - 0 if the GPS and TMC receivers communicate on different ports, 1 if they share one port (for ex. GNS 5843 or Royaltek RTG1001)
But then it will always look for the BT GPS unit. Personally I prefer to switch the TMC section on only if I think I need to when in the car on a longer journey. So I use HD2's internal GPS (port 4) and external TMC (port 2 from GNS5843) Like I went to London on Friday (100miles away). Only in the centre of Canary wharf did the signal become confused. This would be because of the tall, close, glass and steel buildings making multipath GPS signals and only a small and narrow view of the sky immediately above. That is the situation when you put your BT GPS receiver at the sunroof glass looking straight up at sky instead of forward at the buildings blocking the signals from orbit.
Were you using your GNS GPS/TMC device for both signals or just the TMC? The above should cure your problem if you only use the GPS/TMC BT device on port 2.
I am using the internal GPS and bluetooth only for TMC. never had a prolem with lack of sattelite signal of the internal GPS in my car, so have no reason to use it other way.
I agree that the internal GPS receiver in the HD2 is very very powerful (sensitive). I get all 12 windows full of GPS signal even in the middle of my house and accuracy listed as 'high'. But I was just giving an insight to the worse case scenario I had the other day was in the middle of Canary Wharf because of the tall buildings . it would be the only place in the UK with the worst conditions for satellite reception.
The ideal and cheapest solution, for everyone, will be the solution for HyperGPS to work on HD2 with the 3.5mm aerial/headset lead plugged in. I even get a good FM signal through the 3.5mm to 3.5mm lead to connect HD2 to the audio input to the car system. If someone gets or sees the HyperGPS working on the HD2 for igo8 do please let us know. Thanks! in advance.
P.S. by the way ....where is this web site based? I just put this on at 1856 yet it displays at 0656. This site would therefore be ½ way around the world...... Ah! I just noticed there is the pm after it.
Just got my Navilock NL-324BTR. Paid just over £50 from Amazon.de. All is working well. The only niggle I have is that when iGO8 opens, it asks me to confirm the port that I want to use. If I do not select the port then hit "select" in time, the option screen disappears and it does not start.
Anyone any solutions?
To get that screen back you either just tap the BT button to get to that screen again or minimize Igo8 and tap start then Bluetooth then select your device. (I have moved the BT icon to the top (tap and hold) of the HD2 screen.
tomtom
Does anyone know whether there are any workarounds to use any of these tmc receivers with tomtom on the hd2. If not, can someone who used both tomtom and recent Igo give a short pros and cons of the two? I used Igo about 3-4 years ago and I did not like it plus I became used to tomtom.
what is reception quality of gns trafficbox tmc receiver?
Hi,
i am topaz (HTC touch diamond 2) owner and can use hypergps, however i find fm reception of topaz builtin tuner quite poor for tmc needs. In my citroen c5 (worst car for all sort of signals due to its athermic windscreen), tmc reception is poor. I have experimented with various antennas connected to extusb connector, however no real success.
I tried to get magnetic mount fm antena for car roof, but there isnt any available?!
Out of desperation i am now conisdering GNS traffic box (to many $$$...). As i understand there are two versions: lighter plug and external antenna version (both BT). I would buy one of these, and lighter plug seems practical, however i am afraid, that it would have poor recepetion due to athermic windscreen.
tomi
Hi tomi,
I have the GNS for the lighter-plug. The reception in my car (Ford Mondeo) is excellent with the long antenna and not bad with the short antenna - but in your case: I would buy the internal module, which is connected to the antenna of the car-radio, though you cannot take it out of your car.
Best regards
esociarius
Hi mihaid,
I have Tomtom on my second device, but I think there is no possibility to connect a tmc-module to tomtom - they want to sell their own tmc over internet-connection. This was one of the reasons, why I went back to Navigon, which works great on the hd2 (though the Navigon-support is poor).
Best regards
esociarius
For those with athermic front windscreens, place your BT GPS or TMC devices on the rear parcel shelf or attach to a sun/moon roof if you have one. An alternative position if you are a bit DIY is to place under the plastic in the aquarium between the bonnet and windscreen (usually has the windscreen wiper parts there too, needs power and insulation/ water proofing provided) tuck aerial along windscreen rubber).
