GPS System & Address Validation For Delivery Companies

By Adriana Noton

Can you be sure that the package you sent to a client was delivered as promised? If the company you choose for delivery has a GPS System & Address Validation program, you can know for certain. This system is designed to allow a delivery person to use a device that is about the size of a cellular phone to enter the package identification and make a GPS location stamp as well as a time stamp of the package and its delivery. This is an efficient way for the company to ensure that your delivery is always on time.

GPS service allows for very precise location on the face of the earth. Some units are precise enough that they can be used in land surveying. A unit can give a very precise location of the delivery truck when it is in front of a home making delivery or even at the door of the place where the unit is being delivered.

This system can put an end to customer complaints of never receiving the equipment when the delivery company claims to have made the delivery. The driver has GPS documentation of the address where the unit was delivered. If delivery is made to a wrong address, the carrier has the option to return to the address and reclaim equipment delivered to the wrong place.

Another use of this equipment is in the delivery of court papers to an individual. In addition to the manual address verification, the person serving the papers can have GPS address validation that the papers were served to the correct address.

The GPS system was first used experimentally by the US navy in 1960. Since that time several other satellites have been launched. These satellites have been used for airplanes and ships in navigation for years. In more recent times hand held units have become popular and today, many cell phones have included a GPS locator. These much smaller units have made it possible to allow GPS technology to be used for such things as address verification.

One thing that should be taken into consideration is that the US government has a built in error in the system that can cause it to be off as much as 100 meters (over 300 feet or the length of a football field). This error was included in order to prevent take over of the system by enemy forces and use in directing munitions sent by forces attacking the United States. This error must be taken into account in the address verification system. Thus it may not be possible to determine if a package was delivered to your home your next door neighbors, simply due to the fact of the built in error.

GPS address verification is overall a good system, but the driver will still need to use visual clues to make the delivery to the correct place. In addition, the system is very good at giving the driver directions to the next stop.

The technology is available to make this system work very precisely. However, there are still a few bugs to work out and one of those bugs is the error that was built into the system by the US government.
