accessing internet via satelite

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.

Software GPS Driver for Tomtom or Similar

Hi,
I wonder if anyone out there knows if anyone is developing a software GPS driver that could be used with Tomtom or similar route software.
Basically it would not need a hardware GPS receiver as the software would use triangulation of the mobile signal to supply the co-ordinates, i know this would not be as accurate as a proper GPS but it might be a useful thing to have!?
Dan.

Pretty sure that sort of thing is allready out there. The issue is, it would be useless for moving Satellite Navigation, especially at car speeds.
This sort of thing is only viable for the kind of "Wheres my nearest bank/ shop/ post office" etc.
The other side of this is that this system is currently commercially marketed for tracking peoples whereabout, for example employers to keep tabs on their employees or parents to have a system of knowing roughly where their children are.

XDA mini exec to GPS device dev

Hi all,
I am for Uni looking into using a GPS device (just a receiver) to pass your location to a PDA and with some work on some software on the device do some calculations and useful stuff re where you have gone, how fast etc. But the app on the PDA must be custom written
All i need from the GPS device is location (in longitude+latitude?) and this would be queried about every second.
a) how easy is it to get such an output from a receiver without a lot of premade software overhead?
b) just how accurate can GPS be? i read about 10m but down to 2/3m with WAAS?
c) anyone know of any good documentation on using GPS output for a PDA app?
d) any advice on good GPS devices that can do just this but as accurately as poss. i hear about the ability to get down to a few inches but this isnt publically available? (maybe wrong there)
any help or pointers would be very, very much appreciated.
Andy

Most GPS units send navigation data using the NMEA 0183 protocol, which is text-based (and thus easily parsable). Since you mention the XDA mini exec, I assume you're looking at Bluetooth GPS units -- these units will look like a COM port to the XDA, so you can use standard serial comms code to receive the NMEA data.
If you look around the net (e.g. google, sourceforge.net) you should be able to find a number of Windows applications that do what you want. Most of them will have been written for big Windows, but should be easily portable to the XDA platform.

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

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
