Satellite Email via GPS?
mtm_king asks: "Has anyone had any experience with Magellan GSC 100 Satellite Communicator? It is a GPS that does email. (Their web site pricing and info is out of date.) The GSC costs $850 unit, $130 for case and antenna, another $50 in sign up fees, then it is $30 a month for the service. My parents live full time in Mexico (outside of Todo Santos, cool place) and just have a cell phone which is expensive and flaky ($1.00 a minute+ from the US) . Trying to communicating with them is really frustrating. I am thinking about buying one of these units for them,but it is getting close to some 'serious money' considering I do not know how well it works. I know I could try to get their PC on the internet through the cell phone but considering that they have to stand by a window or go outside to use it, and the cost of an ISP and more minutes on the cell phone...well, I am looking for cheaper/more reliable alternatives than that." Would the GSC really work better in this case than using the cell phone modem?
A iridium phone costs (after hidious federal taxes) between $1000 and $1800 depending on model. Their cheapy plan, cost $20 per month for service and $1.50 per min - they have a cradel for $150 that makes the thing behave like a slow serial modem. With a good ISP, it you get 4800 baud. They give you a Windows CD that you can use that will compress the stream and use their ISP. I threw it away - and just use SSH for it's compression on a BSD laptop.
The cool thing - is that most plans charge by ten second increments. Volume plans can get you down to $.60 a min.
Also they work greay in an emergency - I had no trouble getting a line on Sep11, but cell and land line diden't work.
Curious thing though - after Sep11 (around the 25th or so) - Iridium calls took an extra five seconds to connect. I think shady people were being monitered by our frinds at the NSA. Or I could just need to re-adjust my foil hat.
Sorry 'bout the rambeling. I need coffee.
Oh - the best thing about Iridium VS Garmond: You family can use it in an emergency, when communiction is a life saver and not just a novilty for email.
Good luck - sounds like a cool project and I admire you for trying to keep in touch with family.

An email sender must first find a satellite than will pass above you in the next 36 hours (IIRC) and send it the message. When the satellite passes above you, if your unit is on it squirts the data down. Otherwise it's lost. You need a separate program to compute satellite passes and there's no inter-satellite communication. Long delays. It's so complex, there's no way Joe Schmuck can send you an email.
From a moving unit to a ground based station is a little easier: keep your unit on until a satellite passes overhead, that's all.
