whitewater rafting

A fun activity where you put on PFDs (layman; "life jacket"), jump in a rubber raft with little PVC paddles and float down the river....no big deal...until you get flipped over, hit on the head with a rock, hit in the teeth with a paddle, flipped out of the raft, pushed out of the raft, or are simply scared out of your mind and go into fight-or-flight mode with those class 5 rapids coming around the bend.

I was having a fun time whitewater rafting until we hit this class 4 sideways, our raft flipped over, I got sucked into the rapid and popped out about 40 feet away (still holding on to my paddle)...After whitewater rafting (which was a real rush) driving on the beltway doesn't seem so bad.

GPS

Global Positioning System

Complex network of satellites that transmit signals to ground receviers in cars, boats, airplanes (see also VOR). The GPS receiver uses the signals from the satellites (which are over 15,000 miles away!) and uses them to find your location, anywhere in the world, with incredable accuracy.

Without GPS, countless losers who can't use a VOR would be lost"

GSM

Global System for Mobile communications.

The most common digital cellular system in the world. GSM is used all over Europe, plus many countries in the Middle East, Asia, Africa, South America, Australia, and North America. GSM's air interface is based on narrowband TDMA technology, where available frequency bands are divided into time slots, with each user having access to one time slot at regular intervals. Narrow band TDMA allows eight simultaneous communications on a single radio multiplexor and is designed to support 16 half-rate channels. GSM also is the only technology that provides incoming and outgoing data services, such as email, fax, and internet surfing. GSM makes use of a SIM card that allows memory portability between dumb GSM phones.

The GSM system allowed for both internet surfing and digital voice communications over 1900 MHz radio networks.
