accessing internet via satelite

[lanky]

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 :P

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 :P

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 :-)
