// That means if you DON'T change the timestamp, many implementations will simply
// discard subsequent packets that have an identical timestamp. Also, if they
// receive a PDU with an timestamp lower than the last one they received, they
// may discard it as an earlier, out-of-order PDU. So it is a good idea to

// coordinate system with the origin at the center of the earth, the x
// axis out at the equator and prime meridian, y out at the equator and
// 90 deg east, and z up and out the north pole. To place an object on
// the earth's surface you also need a model for the shape of the earth
// (it's not a sphere.) All the fancy math necessary to do this is in
// the SEDRIS SRM package. There are also some one-off formulas for
// doing conversions from, for example, lat/lon/altitude to DIS coordinates.
// Here we use those one-off formulas.
// Modify the position of the object. This will send the object a little
// due east by adding some to the longitude every iteration. Since we
// are on the Pacific coast, this sends the object east. Assume we are
// at zero altitude. In other worlds you'd use DTED to determine the
// local ground altitude at that lat/lon, or you'd just use ground clamping.
