accessing internet via satelite - Networking

I am curious to know as I use my pda for the main purpuse of road navigation but would like to know if also I can access the internet through the gps receiver.

Sorry but that cannot be done, the gps receiver is a receiver only unless its bluetooth in which case it receives the gps signals and transmits them over bluetooth to the phone/pda, it has no capability of satellite communication for internet.

if the gps satelite had access to the internet and would send data and the gsp module had support for recieving data i guess it could be don
but since gps was invented by the us army and they still use it i doubt they would add too much internet support in that system
also it would be a bad thing for all people who were using gps when the whole system would crawl to a halt when little timmy were downloading powerranger mpg's

It couldn't work, how would the satellite receive the page request? To do this, the GPS module would have to be a transceiver...which it isn't.
I guess for this to be possible, you need a satellite chip like in a sat. phone....I wonder if anyone will produce one to go in a CF slot anytime soon? Would be pretty cool!

A GPS Receiver mainly receives clocking signals from different sattellites and calculates your position based on the timedrift between the different clock feeds.
These clockfeeds are actually broadcasted on a singal transponder and single channel for each sattellite... in other words, everyone receives the same stream... so no luck there
Regardless of that fact, a GPS receiver is usually pretty dump and doesnt have the brain to maintain Layer 2 (let alone 3) cohesion for a data stream.
Anyways... my 2c

Navi using GSM Cell ID Info

Hi people,
Everyone is so excited with GPS navi solution, I was wondering if there is currently a software that allows basic navi using the Cell ID Broadcaseted from our current GSM network. I know that it may not be as accurate as a GPS navi system but it should be more that enough to tell the navi software to load the correct map and allow one to see what is around your area.
Well there are other advantages over GPS:
- Able to use the navi system undergound where GPS signal is not reachable. Eg, basement carpar, underground highways, etc. You will be able to use it whenever there is GSM coverage!
- No expensive GPS hardware required. The idealised situation is that the PDA is able to pair a bluetooth enabled handphone and the phone will feed the navi software with the current cell ID. If one have a XDA, that would be even better! You can then use your blue connection for your BT headset!
I have come across this software called Agis Navfone. Too bad it runs on Symbian Phones only... Does anyone out there have any ideal? If not, why not we can start some development in this direction? I'm a hobbist programmer, maybe someone can point to some info that shows me how to extract CellID in PocketPC. There's another what is to programme a virtual GPS device which will actually convert the CellID of the current network at translate it to something which most navi software will understand. THanks.

GPS on Hermes without receiver. Possible?

Hi guys n girls,
I'm kinda new here and I have a question I've been dying to ask since I got hold of my HTC hermes. I'm currently using Vodafone's version of HTC Hermes, which is the V1605.
Is it possible for HTC Hermes to use GPS navigation without an external GPS receiver such as a bluetooth device? I learnt that HTC Hermes has no GPS chipset so it will definitely need a receiver, but I'm just curious and I wanna confirm. Thanks
Afaik, it got a GPS Chipset but no antenna
http://forum.xda-developers.com/showthread.php?t=292466
http://forum.xda-developers.com/showthread.php?t=291181
thanks for the clarification.
so, it will need a receiver to act like an antenna?
I'm not sure if you search for GPS or looked at the Wiki on the Hermes but its been covered a few times. The only thing you can really do is get a bluetooth GPS receiver or something along those lines.
Read and Search

I use a Holox bt-321 GPS receiver, works fine!
I was going to link to an ebay auction for one but its possibly the ONLY day when there isnt an auction for one!
I bought here from a user a Holux M-1000. Works fine and without any problems.
Give Navizon a go - > http://www.navizon.com/
its a virtual GPS for phones without GPS, Goes on Phone Cell info and Wifi AP Signals, you have to use wifi but it does pinpoint where you are better with wifi on
also out puts the data via a com port so you can use Satnav an other GPS enabled apps with it
Garmin GPS 10
I'm using an older Garmin GPS 10 that I purchased a few years ago, but it stills works great. It is rechargeable and the battery seems to last forever. I also using the Beta version of Garmin's Mobile XT, which gives my 8525 the same look and feel as "modern" GPS-only devices.
Some of the cool "toys" the software uses is:
2-D or 3-D map view
PeerPoints (sending GPS coords via SMS or MMS)
Local gas prices near you
Real time traffice
Weather
POIs ( you can have up to 4,000 waypoints/favorites/locations)
Voice prompts
Hotels.com info
etc.
Of course, some of the features depends on whether or not you have a data plan or WiFi access. I also like it because it is very small, works via bluetooth and is very accurate. I also use BeelineGPS because I also like to Geocache.

P.S. The current version of my GPS is the Garmin Mobile 10 for PDAs/Laptops
im using a "54 channel Holox" (Fake Holux) but i havent seen a quicker connecting device

Use external BT GPS receiver?

Apparently my cars GPS radio is accessible via BT. Is there a way to get my N1 to use that rather than the internal GPS radio? Reports from users of other phone OSs seems to indicate it locks faster and holds signal better so I'd like to give it a try.

[Q] BT Serial Port SPP (rfcomm) maybe someday?

I can't post this in development because I an still a nobody ...
Would it be possible to add in rfcomm for Bluetooth SPP serial port? The Nook would make a great tablet for telescope mount control over BT. You can't do it with the iPad due to the security around the BT stacks. It would also allow NEMA GPS modules to be read for different applications.
I'm running CM7 7.0.2 and this isn't yet available.
Just a dream?
Not sure if this is what you're talking about, but you can send the GPS data to the Nook form a GPS device like a Cell phone or GPS receiver. I use a stand alone GPS receiver and sometimes my Droid cell phone to send my location to the Nook to use CoPilot and Google Maps on the Nook. That's at least half of what you're talking about right?

Hmm, you got me pondering...
I got out my trusty Garmin GPS 10 and I can pair but it's not connected. That could be for a couple of reasons (the Nook only connects on demand maybe.) But if what you are saying is correct, maybe it does support SPP since it uses a comm port for the GPS.
But, when I connected from my notebook and checked the services, SPP wasn't one of them (just OPEX and AD2P.) I will keep playing but I half expect that part of the SPP stack requirements are missing.
On the plus side, if the GPS will work too, that is a second plus since it's nice to be able to ask the GPS for the specific time and location during the telescope setup (it matters.)
I'll look for an app in the Market that might read an external GPS devices and show the location. I notice most apps are for reading the phone GPS (which we don't have.)
Thanks!
Android does not support SPP, but there are multiple apps in the market which do, Bluetooth GPS Provider is the one which I prefer as it works very well and just works no matter what.
Thanks folks,
I fired up the Garmin GPS 10 and it works using Bluetooth GPS. That means an application can add in the SPP. That is perfect and gives us hope!
I really appreciate the responses!

Yes, apps can directly talk with a Blutooth GPS. There are a handful which do this, or again, Bluetooth GPS Provider will provide the BT GPS to every app that asks for GPS.
This isn't only about GPS. GPS is just one aspect. I want to communicate with any serial device over BT. My understanding from reading it that rfcomm and the applications can supply that function.
What I did notice last night is that even without an application that supplies rfcomm, the Nook would still discover the devices unlike the iPad. I could pair to pretty much anything I wanted but it wouldn't connect. That's normal from my perspective.
At least I know it can be made to work.

Well, the XOOM does at least. Not sure whether it was Motorola's or Google's doing though. I use a Bluetooth to Serial adapter from Roving Networks quite successfully with it. I'm unaware of any other devices that do it.
I agree that native Android doesn't support SPP but the rfcomm library does and if it's linked into the application, SPP works.
Now if I can only find a way to use VNC to control my PPC from the Nook without going through a remote server (maybe via adhoc or BT ...)
Any device at API level 5 (2.0) or above may support BluetoothSocket, RFCOMM and therefore SPP unless the OEM did something to screw it up.

Help with using navigation on an Xtrons HU

Posting here as I think I used the wrong secrtion previously
I recently installed a Xtrons PQS90MTVL head unit in a skoda superb. I have a couple of questions on how to get it to work correctly when navigating.
1) It seems that you can set the navigation sounds to be a percentage of the radio volume but cannot set it to play at a given volume regardless. The problem is that the radio seems to be constantly on and there is no way to turn it off. The 'on/off' button simply mutes the radio - and the navigation sounds.
Often I am in an area where I cannot pick up a decent radio signal on the programme I want and just get static. In these situations I want to turn the radio off but still hear navigation sounds. I don't want to listen to loud static just so I can have the nav sounds play at a percentage of that static. Is there a way to turn the radio off but still get navigation sounds? (a workaround I have found is to play a media file instead of the radio and then pause playback. The nav sounds are then still a percentage of the - non existent - playback volume. However this should not be necessary)
2) It also seems that a Internet connection is needed for any navigation. even google maps won't do a search without it as it says I am offline. (is this true?)
I have bought the 4G wifi dongle but have a question about its use. Does the HU connect to the dongle, as far as data is concerned, via the USB socket that comes out of the back of the unit or is that socket simply powering the dongle and the HUI is actually connecting to it over wifi using the dongle as a hotspot? If so then I don't have to use the wired usb socket from the unit (which I suspect is underpowered) and can plug the dongle into an ordinary 2A USB socket that I have in the car, positioning the dongle near the roof for a better signal
Incidentally I did try using Android Auto with my phone using wired connection. That seems sort of OK but is not very reliable. Often when starting the car it hangs at the 'connected' screen, or even at the 'trying to connect' screen, although other times it seems OK
3) There is a small socket on the left hand side of the HU that looks like a slot for a small memory card or a sim card. It is labelled 'GPS'. What is that socket used for? it is not mentioned in the manual as far as I can see. - The manual is generally a bit hand waving though, excitedly telling you what you can do but not how to do it.
(I did try the xtrons forum but not only are the last posts there around January 2022 but there seems to be no way to register for it. Hence posting here)

First of all you need to fix your FM reception. You need to use a phantom power adapter to get some voltage to the OEM antenna.
There are some navigation apps which don´t need a internet connection. TomTom as example and others using offline maps. But you won´t get traffic messages if you don´t have an internet connection.
That would fix your white noise.
The FM radio can be closed if you use the back button on top right. If that does not help, chose the recent apps button on top and swipe the radio app away as for each other app... You really should learn how to use Android.
The navigation loudness can be set in the system settings. Depends on the unit where you can find it. In this case the navigation software needs to be registered as navigation in settings /Apps/Standard apps.
Regarding your 4G-WiFi dongle... The name itself shows the functionality.
It connects via 4G to the internet and provides the connection via WiFi to anyone in the car.... even too to the radio.
The GPS slot on your radio is nothing else as a micro-SD slot, which also can be used to store music on it or whatever else you want.
BTW: Seems that you are not that familiar with car electronics. May be a good idea to ask someone who can help you with some knowledge what has to be done.
Might be an easy task to just swap a radio, but there are more things behind than just swapping.
May I recommend 'Magic Earth' navigation, works fine with no internet but no live data of course.
At least there are a lot more offline navigation apps...
Out of memory:
Google Maps (partially with downloaded segmented maps)
HERE WeGo
Navmii GPS World
OsmAnd
MAPS.ME
Magic Earth

But without internet... no traffic data..

Thanks for a helpful reply. I have already fitted a power injector for the FM antenna which made some difference but I like to listen to radio 4 and there are parts of the country (along the M11, on the A5 in North Wales), where you cannot pick it up on any radio - and of course in Europe where I have just been for a few weeks where I usually don't want the radio on at all. That's why having the nav sound set as a percentage of the existing volume seems a bit odd as it implies you already have some other sound on. Better to have a dedicated channel for it or have the nav mute any other sound.
I'll look at doing all the swiping etc to turn off the radio by closing recent apps although this doesn't seen like a very safe thing to start doing when you drive into a area of poor reception. I was hoping the unit would have a simple press button like in the good old days!
The dongle info is also useful thank you. Xtrons do not make this clear at all. They imply that by plugging it into the socket on the unit you have made a (wired) data connection. If the HU is still only connecting over wifi anyway then I can install the dongle wherever I like in the car so that it gets a good 4G signal, instead of it having to be in the driver footwell at the end of the short USB cable xtrons supply and I can use a dedicated 2A usb adaptor to supply decent power .
I guessed the 'GPS' socket might have nothing to do with GPS. Shame Xtrons couldn't say what it was for instead of just mis-labelling it.
Incidentally. The SIM in the dongle would only ever be used for the navigation to receive traffic updates or bits of map or whatever it needs i.e I don't intend to be surfing the net or downloading Utube videos. Do you have any idea what sort of data requirements this would mean. Would a 250Mb a month sim be enough?
I'll experiment with your suggestions.

I'll look into those thank you. I use maps.me on my phone but couldn't get google maps to work on the HU as it said I was offline. Of course I still need an internet connection to download any of those apps and install them on the HU but I could just park near my house and using the house wifi.
Data plan for using navigation online data depends on the app you use and the amount of mileage per month.
You can use your smartphone first to see what you need in a "normal usage" month and then decide what you need.
If you use any offline map solution, it´s also some sort of usage dependency.
BTW... If you would invest into a higher data plan (2GB), you could use the app Radionator to use Online radio. BBC Radio4 should be in there too. Radionator is the best alternative if you want to listen to one specific radio station. Just needs a stable internet connection, nothing else... and the sound is mostly better than FM.
May be you can use the Navradio+ as alternativ solution for receiving FM radio. Depends on the MCU of your unit. Search for it in MTCD software forum.

I would recommend to use HERE WeGo, it served me very well for the years I didn't have mobile internet connection. Also it shows the max allowed speed in most countries, whereas Google Maps doesn't do that.
Sure, Here WeGo is a good choice, even without internet connection.
