GPS Utility is the software program used to download the data from the GPS machines. GPS Utility is a public domain software that is available for download from the Internet. One license is registered for each DHS survey. Generally, the manager should make sure the software is shipped with the GPS units.

how to use GPS unit: the basics of using the gps unit should be covered: on/off, initializing the unit and adjusting settings (datum, coordinate system, measurement units), acquiring a position, checking satellite coverage, marking a position with point averaging, changing the waypoint name, renaming and deleting waypoints, as well as adjusting contrast, light, and time/day. most popular brand gps devices are easy to use,like garmin etc.

there are some drawbacks with GPS receivers. The accuracy of the GPS receiver’s calculated position depends on the strength and number of signals that it receives. The gps receiver will always collect data from as many satellites as it can, and will choose the best four according to angle and strength of signal from which to compute a position (see previous section on GPS accuracy). But obstacles such as buildings, mountains, and tree canopies can distort the signals and introduce error to the reading. Even more serious, user mistakes such …

GPS receivers accuracy comparison. There are several types of GPS receivers in use. the GPS receivers accuracy depend on its grade.
Survey grade gps receivers are the most accurate and the most expensive. Typically these receivers have sub-centimeter accuracy and cost in the tens of thousands of US dollars. Mapping grade gps receivers typically can produce sub-meter accuracy and cost between US$1,000 and US$5,000 and are designed for high-end cartographic activity. Recreational grade GPS units are designed for use when hunting, hiking, boating etc. Of the three types described, recreational receivers …

bluetooth enabled GPS advantages. it means that you will have both features of bluetooth and gps. Bluetooth is simply a way of transferring data over a very short distance between 2 devices with Bluetooth enabled,usually several meters. So the advantage is if you can transfer data between your mobile phone or laptop or other device with bluetooth to your GPS device. if you need it, you should pay more than an extra $15-$30 for a bluetooth enabled GPS over non-bluetooth GPS systems.
Bluetooth will also allow you to answer your …

GPS is “Global Positioning System”. it is a satellite-based radio navigation system. GPS itself is made up of three component groups – the satellite constellation, ground control segment, and user equipment. The satellite constellation is often referred to as NAVSTAR (Navigation Satellite Timing and Ranging) and currently consists of 30 satellites. Groups of five satellites loop around the earth in one of six different orbital paths. This allows a system user with a clear view of the sky to have access to a minimum of four satellites at any …
